Xcode Build Settings

Core Build System

  • Active Build Action ACTION

    A string identifying the build system action being performed.

    Type string
  • Additional SDKs ADDITIONAL_SDKS

    The locations of any sparse SDKs that should be layered on top of the one specified by Base SDK (SDKROOT). If more than one SDK is listed, the first one has highest precedence. Every SDK specified in this setting should be a “sparse” SDK, for example, not an SDK for an entire macOS release.

    Type StringList
  • Alternate Install Group ALTERNATE_GROUP

    The group name or gid for the files listed under the Alternate Permissions Files (ALTERNATE_PERMISSIONS_FILES) setting.

    Type String
    Default Value $(INSTALL_GROUP)
  • Alternate Install Permissions ALTERNATE_MODE

    Permissions used for the files listed under the Alternate Permissions Files (ALTERNATE_PERMISSIONS_FILES) setting.

    Type String
    Default Value $(INSTALL_MODE_FLAG)
  • Alternate Install Owner ALTERNATE_OWNER

    The owner name or uid for the files listed under the Alternate Permissions Files (ALTERNATE_PERMISSIONS_FILES) setting.

    Type String
    Default Value $(INSTALL_OWNER)
  • Alternate Permissions Files ALTERNATE_PERMISSIONS_FILES

    List of files to which the alternate owner, group and permissions are applied.

    Type StringList
  • Always Search User Paths (Deprecated) ALWAYS_SEARCH_USER_PATHS

    This setting is deprecated as of Xcode 8.3 and may not be supported in future versions. It is recommended that you disable the setting.

    If enabled, both #include <header.h>-style and #include "header.h"-style directives search the paths in User Header Search Paths (USER_HEADER_SEARCH_PATHS) before Header Search Paths (HEADER_SEARCH_PATHS). As a consequence, user headers, such as your own String.h header, have precedence over system headers when using #include <header.h>. This is done using the -iquote flag for the paths provided in User Header Search Paths (USER_HEADER_SEARCH_PATHS). If disabled and your compiler fully supports separate user paths, user headers are only accessible with #include "header.h"-style preprocessor directives.

    For backwards compatibility reasons, this setting is enabled by default. Disabling it is strongly recommended.

    Type Boolean
    Default Value YES
  • Require Only App-Extension-Safe API APPLICATION_EXTENSION_API_ONLY

    When enabled, this causes the compiler and linker to disallow use of APIs that are not available to app extensions and to disallow linking to frameworks that have not been built with this setting enabled.

    Type bool
    Default Value NO
  • Convert Copied Files APPLY_RULES_IN_COPY_FILES

    Enabling this setting will cause files in the target’s Copy Files build phases to be processed by build rules. For example, property list files (.plist) and strings files will be converted as specified by Property List Output Encoding (PLIST_FILE_OUTPUT_FORMAT) and Strings File Output Encoding (STRINGS_FILE_OUTPUT_ENCODING), respectively.

    Type Boolean
    Default Value NO
  • Process Header Files APPLY_RULES_IN_COPY_HEADERS

    Enabling this setting will cause all Public and Private headers in the target’s Copy Headers build phase to be processed by build rules. This allows custom build rules to be defined to process these headers. Custom script rules can define their outputs relative to HEADER_OUTPUT_DIR, which will be provided to that script, taking the header visibility into account. The scripts are also passed SCRIPT_HEADER_VISIBILITY (“public” or “private”). Files that should not be processed by build rules may need to be moved to a Copy Files build phase when this setting is enabled.

    Type Boolean
    Default Value NO
  • Architectures ARCHS

    A list of the architectures for which the product will be built. This is usually set to a predefined build setting provided by the platform. If more than one architecture is specified, a universal binary will be produced.

    Type StringList
    Default Value $(ARCHS_STANDARD)
  • Asset Pack Manifest URL Prefix ASSET_PACK_MANIFEST_URL_PREFIX

    If set to anything other than the empty string, every URL in the AssetPackManifest.plist file will consist of this string with the name of the asset pack appended. If not set, the URLs in the AssetPackManifest.plist will be formed as appropriate for the build location of the asset packs. The prefix string is not escaped or quoted in any way, so any necessary escaping must be part of the URL string. This setting affects only URLs in the AssetPackManifest.plist file — it does not affect where asset packs are built in the local file system.

    Type StringList
    Default Value normal
  • Built Products Dir BUILT_PRODUCTS_DIR

    Identifies the directory under which all the product’s files can be found. This directory contains either product files or symbolic links to them. Run Script build phases can use the value of this build setting as a convenient way to refer to the product files built by one or more targets even when these files are scattered throughout a directory hierarchy (for example, when DEPLOYMENT_LOCATION is set to YES.

    Type StringList
  • Strip Debug Symbols During Copy COPY_PHASE_STRIP

    Specifies whether binary files that are copied during the build, such as in a Copy Bundle Resources or Copy Files build phase, should be stripped of debugging symbols. It does not cause the linked product of a target to be stripped—use Strip Linked Product (STRIP_INSTALLED_PRODUCT) for that.

    Type Boolean
    Default Value NO
  • Enable Bitcode ENABLE_BITCODE

    Activating this setting indicates that the target or project should generate bitcode during compilation for platforms and architectures that support it. For Archive builds, bitcode will be generated in the linked binary for submission to the App Store.

    Type Boolean
    Default Value NO
  • Enable Testing Search Paths ENABLE_TESTING_SEARCH_PATHS

    Specifies whether the build system should add the search paths necessary for compiling and linking against XCTest. This setting is enabled by default if the target is a unit test target or if the target explicitly links to the XCTest framework.

    A list of patterns (as defined by fnmatch(3)) specifying the names of source files to explicitly exclude when processing the files in the target’s build phases (see also Included Source File Names (INCLUDED_SOURCE_FILE_NAMES)). This setting can be used to define complex filters for which files from the phase should be built in response to other build settings; for example, a value of *.$(CURRENT_ARCH).c could serve to exclude particular files based on the architecture being built.

    Type StringList
  • Executable Extension EXECUTABLE_EXTENSION

    This is the extension used for the executable product generated by the target, which has a default value based on the product type.

    Type String

  • Perform Single-Object Prelink GENERATE_MASTER_OBJECT_FILE

    Activating this setting will cause the object files built by a target to be prelinked using ld -r into a single object file, and that object file will then be linked into the final product. This is useful to force the linker to resolve symbols and link the object files into a single module before building a static library. Also, a separate set of link flags can be applied to the prelink allowing additional control over, for instance, exported symbols.

    Type Boolean
    Default Value NO

  • Kext Cplusplusflags KEXT_CPLUSPLUSFLAGS
    Type StringList
    Default Value $(KEXT_CFLAGS)
  • Path to Linker Dependency Info File LD_DEPENDENCY_INFO_FILE

    This setting defines the path to which the linker should emit information about what files it used as inputs and generated. Xcode uses this information for its dependency tracking. Setting the value of this setting to empty will disable passing this option to the linker.

    Type Path
    Default Value $(OBJECT_FILE_DIR_$(CURRENT_VARIANT))/$(CURRENT_ARCH)/$(PRODUCT_NAME)_dependency_info.dat
  • Dynamic Library Allowable Clients LD_DYLIB_ALLOWABLE_CLIENTS

    This setting restricts the clients allowed to link a dylib by passing -allowable_client to the linker for each supplied value.

    Type StringList
  • Dynamic Library Install Name LD_DYLIB_INSTALL_NAME

    Sets an internal install path (LC_ID_DYLIB) in a dynamic library. Any clients linked against the library will record that path as the way dyld should locate this library. If this option is not specified, then the -o path will be used. This setting is ignored when building any product other than a dynamic library. See Dynamic Library Programming Topics.

    Type Path
  • Write Link Map File LD_GENERATE_MAP_FILE

    Activating this setting will cause the linker to write a map file to disk, which details all symbols and their addresses in the output image. The path to the map file is defined by the Path to Link Map File (LD_MAP_FILE_PATH) setting.

    Type Boolean
    Default Value NO
  • Path to Link Map File LD_MAP_FILE_PATH

    This setting defines the path to the map file written by the linker when the Write Link Map File (LD_GENERATE_MAP_FILE) setting is activated. By default, a separate file will be written for each architecture and build variant, and these will be generated in the Intermediates directory for the target whose product is being linked.

    Type Path
    Default Value $(TARGET_TEMP_DIR)/$(PRODUCT_NAME)-LinkMap-$(CURRENT_VARIANT)-$(CURRENT_ARCH).txt
  • Generate Position-Dependent Executable LD_NO_PIE

    Activating this setting will prevent Xcode from building a main executable that is position independent (PIE). When targeting macOS 10.7 or later, PIE is the default for main executables, so activating this setting will change that behavior. When targeting OS X 10.6 or earlier, or when building for i386, PIE is not the default, so activating this setting does nothing.

    You cannot create a PIE from .o files compiled with -mdynamic-no-pic. Using PIE means the codegen is less optimal, but the address randomization adds some security.

    Type bool
    Default Value NO
  • Quote Linker Arguments LD_QUOTE_LINKER_ARGUMENTS_FOR_COMPILER_DRIVER

    This setting controls whether arguments to the linker should be quoted using -Xlinker. By default, Xcode invokes the linker by invoking the driver of the compiler used to build the source files in the target, and passing -Xlinker to quote arguments will cause the compiler driver to pass them through to the linker (rather than trying to evaluate them within the driver). By default, this setting is enabled. Disabling it will cause Xcode to not use -Xlinker to pass arguments to the linker. Disabling this setting is useful if the target has instructed Xcode to use an alternate linker (for example, by setting the LD setting to the path to another linker) and that alternate linker does not recognize -Xlinker.

    Type Boolean
    Default Value YES
  • Runpath Search Paths LD_RUNPATH_SEARCH_PATHS

    This is a list of paths to be added to the runpath search path list for the image being created. At runtime, dyld uses the runpath when searching for dylibs whose load path begins with @rpath/. See Dynamic Library Programming Topics.

  • Intermediate Build Files Path OBJROOT

    The path where intermediate files will be placed during a build. Intermediate files include generated sources, object files, etc. Shell script build phases can place and access files here, as well. Typically this path is not set per target, but is set per project or per user. By default, this is set to $(PROJECT_DIR)/build.

    Type Path
    Default Value $(SYMROOT)
  • Build Active Architecture Only ONLY_ACTIVE_ARCH

    If enabled, only the active architecture is built. This setting will be ignored when building with a run destination which does not define a specific architecture, such as a ‘Generic Device’ run destination.

    Type Boolean
    Default Value NO
  • On Demand Resources Initial Install Tags ON_DEMAND_RESOURCES_INITIAL_INSTALL_TAGS

    Defined a set of initial On Demand Resources tags to be downloaded and installed with your application.

    Type StringList
  • On Demand Resources Prefetch Order ON_DEMAND_RESOURCES_PREFETCH_ORDER

    Once your app is installed, this defined a set of On Demand Resources tags that should be downloaded. These tags are downloaded after the initial installation of your application, and will be downloaded in the order the tags provided in the list from first to last.

    Type StringList
  • Order File ORDER_FILE

    The path to a file that alters the order in which functions and data are laid out.

    For each section in the output file, any symbol in that section that are specified in the order file is moved to the start of its section and laid out in the same order as in the order file. Order files are text files with one symbol name per line. Lines starting with a # are comments. A symbol name may be optionally preceded with its object file leafname and a colon (for example, foo.o:_foo). This is useful for static functions/data that occur in multiple files. A symbol name may also be optionally preceded with the architecture (for example, ppc:_foo or ppc:foo.o:_foo). This enables you to have one order file that works for multiple architectures. Literal C-strings may be ordered by quoting the string in the order file (for example, "Hello, world\n").

    Generally you should not specify an order file in Debug or Development configurations, as this will make the linked binary less readable to the debugger. Use them only in Release or Deployment configurations.

    Type String

    • same-as-input
    • XML
    • binary
    Default Value same-as-input
  • Precompiled Header Uses Files From Build Directory PRECOMPS_INCLUDE_HEADERS_FROM_BUILT_PRODUCTS_DIR

    This setting allows for better control of sharing precompiled prefix header files between projects. By default, Xcode assumes that the prefix header file may include header files from the build directory if the build directory is outside of the project directory. Xcode cannot determine this ahead of time since other projects may not have been built into the shared build directory at the time the information is needed.

    If your prefix file never includes files from the build directory you may set this to NO to improve sharing of precompiled headers. If the prefix does use files from a build directory that is inside your project directory, you may set this to YES to avoid unintended sharing that may result in build failures.

    Type Boolean
    Default Value YES
  • Precomp Destination Dir PRECOMP_DESTINATION_DIR
    Type Path
    Default Value $(TARGET_TEMP_DIR)/PrefixHeaders
  • Don't Dead-Strip Inits and Terms PRESERVE_DEAD_CODE_INITS_AND_TERMS

    Activating this setting, in combination with the Dead Code Stripping (DEAD_CODE_STRIPPING) (-dead_strip) option, causes the -no_dead_strip_inits_and_terms flag to be passed to ld(1) via cc(1) to disable dead code stripping for initialization and termination routines. This option should not be used without the aforementioned Dead Code Stripping (DEAD_CODE_STRIPPING) option.

    Type PathList
  • Scan All Source Files for Includes SCAN_ALL_SOURCE_FILES_FOR_INCLUDES

    Activating this setting will cause all source files to be scanned for includes (for example, of header files) when computing the dependency graph, in which case if an included file is changed then the including file will be rebuilt next time a target containing it is built. Normally only certain types of files, such as C-language source files, are scanned.

    This setting is useful if your project contains files of unusual types, which are compiled using a custom build rule.

    Type Boolean
    Default Value NO
  • Base SDK SDKROOT

    The name or path of the base SDK being used during the build. The product will be built against the headers and libraries located inside the indicated SDK.

Additional SDKs can be specified in the Additional SDKs (ADDITIONAL_SDKS) setting.

    Type Path
  • Symbol Ordering Flags SECTORDER_FLAGS

    These flags are typically used to specify options for ordering symbols within segments, for example the -sectorder option to ld.

  • System Framework Search Paths SYSTEM_FRAMEWORK_SEARCH_PATHS

    This is a list of paths to folders containing system frameworks to be searched by the compiler for both included or imported header files when compiling C, Objective-C, C++, or Objective-C++, and by the linker for frameworks used by the product. The order is from highest to lowest precedence. Paths are delimited by whitespace, so any paths with spaces in them need to be properly quoted. This setting is very similar to “Framework Search Paths”, except that the search paths are passed to the compiler in a way that suppresses most warnings for headers found in system search paths. If the compiler doesn’t support the concept of system framework search paths, then the search paths are appended to any existing framework search paths defined in “Framework Search Paths”.

    Type PathList
  • System Header Search Paths SYSTEM_HEADER_SEARCH_PATHS

    This is a list of paths to folders to be searched by the compiler for included or imported system header files when compiling C, Objective-C, C++, or Objective-C++.

    This is a list of paths to folders to be searched by the compiler for included or imported user header files (those headers listed in quotes) when compiling C, Objective-C, C++, or Objective-C++. Paths are delimited by whitespace, so any paths with spaces in them need to be properly quoted. See Always Search User Paths (Deprecated) (ALWAYS_SEARCH_USER_PATHS) for more details on how this setting is used. If the compiler doesn’t support the concept of user headers, then the search paths are prepended to the any existing header search paths defined in Header Search Paths (HEADER_SEARCH_PATHS).

    Type PathList
  • Use Header Maps USE_HEADERMAP

    Enable the use of Header Maps, which provide the compiler with a mapping from textual header names to their locations, bypassing the normal compiler header search path mechanisms.

  • Always Search User Paths (Deprecated) ALWAYS_SEARCH_USER_PATHS

    This setting is deprecated as of Xcode 8.3 and may not be supported in future versions. It is recommended that you disable the setting.

    If enabled, both #include <header.h>-style and #include "header.h"-style directives search the paths in User Header Search Paths (USER_HEADER_SEARCH_PATHS) before Header Search Paths (HEADER_SEARCH_PATHS). As a consequence, user headers, such as your own String.h header, have precedence over system headers when using #include <header.h>. This is done using the -iquote flag for the paths provided in User Header Search Paths (USER_HEADER_SEARCH_PATHS). If disabled and your compiler fully supports separate user paths, user headers are only accessible with #include "header.h"-style preprocessor directives.

    For backwards compatibility reasons, this setting is enabled by default. Disabling it is strongly recommended.

  • Order File ORDER_FILE

    The path to a file that alters the order in which functions and data are laid out.

    For each section in the output file, any symbol in that section that are specified in the order file is moved to the start of its section and laid out in the same order as in the order file. Order files are text files with one symbol name per line. Lines starting with a # are comments. A symbol name may be optionally preceded with its object file leafname and a colon (for example, foo.o:_foo). This is useful for static functions/data that occur in multiple files. A symbol name may also be optionally preceded with the architecture (for example, ppc:_foo or ppc:foo.o:_foo). This enables you to have one order file that works for multiple architectures. Literal C-strings may be ordered by quoting the string in the order file (for example, "Hello, world\n").

    Generally you should not specify an order file in Debug or Development configurations, as this will make the linked binary less readable to the debugger. Use them only in Release or Deployment configurations.

    Type Path
  • Precompile Prefix Header PRECOMPILE_PREFIX_HEADER
    Type Boolean
  • Precompiled Header Uses Files From Build Directory PRECOMPS_INCLUDE_HEADERS_FROM_BUILT_PRODUCTS_DIR

    This setting allows for better control of sharing precompiled prefix header files between projects. By default, Xcode assumes that the prefix header file may include header files from the build directory if the build directory is outside of the project directory. Xcode cannot determine this ahead of time since other projects may not have been built into the shared build directory at the time the information is needed.

    If your prefix file never includes files from the build directory you may set this to NO to improve sharing of precompiled headers. If the prefix does use files from a build directory that is inside your project directory, you may set this to YES to avoid unintended sharing that may result in build failures.

    Type Boolean
    Default Value NO
  • Implicit ownership types on out parameters CLANG_WARN_OBJC_EXPLICIT_OWNERSHIP_TYPE

    Warn about implicit ownership types on Objective-C object references as out parameters. For example, declaring a parameter with type NSObject** will produce a warning because the compiler will assume that the out parameter’s ownership type is __autoreleasing.

    Type Boolean
    Default Value NO
  • Repeatedly using a __weak reference CLANG_WARN_OBJC_REPEATED_USE_OF_WEAK

    Warn about repeatedly using a weak reference without assigning the weak reference to a strong reference. This is often symptomatic of a race condition where the weak reference can become nil between accesses, resulting in unexpected behavior.

    Choose a standard or non-standard C language dialect.

    • ANSI C: Accept ISO C90 and ISO C++, turning off GNU extensions that are incompatible. -ansi Incompatible GNU extensions include the asm, inline, and typeof keywords (but not the equivalent ` asm , inline , and typeof ` forms), and the // syntax for comments. This setting also enables trigraphs.

    • C89: Accept ISO C90 (1990), but not GNU extensions. -std=c89

    • GNU89: Accept ISO C90 and GNU extensions. -std=gnu89

    • C99: Accept ISO C99 (1999), but not GNU extensions. -std=c99

    • GNU99: Accept ISO C99 and GNU extensions. -std=gnu99

    Default Value NO
  • Allow 'asm', 'inline', 'typeof' GCC_ENABLE_ASM_KEYWORD

    Controls whether asm, inline, and typeof are treated as keywords or whether they can be used as identifiers.

    Type Boolean
    Default Value YES
  • Recognize Builtin Functions GCC_ENABLE_BUILTIN_FUNCTIONS

    Controls whether builtin functions that do not begin with __builtin_ as prefix are recognized.

    GCC normally generates special code to handle certain builtin functions more efficiently; for instance, calls to alloca may become single instructions that adjust the stack directly, and calls to memcpy may become inline copy loops. The resulting code is often both smaller and faster, but since the function calls no longer appear as such, you cannot set a breakpoint on those calls, nor can you change the behavior of the functions by linking with a different library. In addition, when a function is recognized as a builtin function, GCC may use information about that function to warn about problems with calls to that function, or to generate more efficient code, even if the resulting code still contains calls to that function. For example, warnings are given with -Wformat for bad calls to printf, when printf is built in, and strlen is known not to modify global memory.

    Type Boolean
    Default Value YES
  • Enable C++ Exceptions GCC_ENABLE_CPP_EXCEPTIONS

    Enable C++ exception handling. Generates extra code needed to propagate exceptions. For some targets, this implies GCC will generate frame unwind information for all functions, which can produce significant data size overhead, although it does not affect execution. If you do not specify this option, GCC will enable it by default for languages like C++ that normally require exception handling, and disable it for languages like C that do not normally require it. However, you may need to enable this option when compiling C code that needs to interoperate properly with exception handlers written in C++.

    Type Boolean
    Default Value YES
  • Enable C++ Runtime Types GCC_ENABLE_CPP_RTTI

    Enable generation of information about every class with virtual functions for use by the C++ runtime type identification features (dynamic_cast and typeid). If you don’t use those parts of the language, you can save some space by using this flag. Note that exception handling uses the same information, but it will generate it as needed.

    Type Boolean
    Default Value YES
  • Enable Exceptions GCC_ENABLE_EXCEPTIONS

    Enable exception handling. Generates extra code needed to propagate exceptions. For some targets, this implies GCC will generate frame unwind information for all functions, which can produce significant data size overhead, although it does not affect execution. If you do not specify this option, GCC will enable it by default for languages like C++ and Objective-C that normally require exception handling, and disable it for languages like C that do not normally require it. However, you may need to enable this option when compiling C code that needs to interoperate properly with exception handlers written in other languages. You may also wish to disable this option if you are compiling older programs that don’t use exception handling.

    Type Boolean
    Default Value YES

  • Recognize Pascal Strings GCC_ENABLE_PASCAL_STRINGS

    Recognize and construct Pascal-style string literals. Its use in new code is discouraged.

    Pascal string literals take the form "\pstring" . The special escape sequence \p denotes the Pascal length byte for the string, and will be replaced at compile time with the number of characters that follow. The \p may only appear at the beginning of a string literal, and may not appear in wide string literals or as an integral constant.

    Type Boolean
    Default Value YES
  • Enable Trigraphs GCC_ENABLE_TRIGRAPHS

    Controls whether or not trigraphs are permitted in the source code.

    Type Boolean
    Default Value NO
  • Relax IEEE Compliance GCC_FAST_MATH

    Enables some floating point optimizations that are not IEEE754-compliant, but which usually work. Programs that require strict IEEE compliance may not work with this option.

    Type Boolean
    Default Value NO
  • Generate Debug Symbols GCC_GENERATE_DEBUGGING_SYMBOLS

    Enables or disables generation of debug symbols. When debug symbols are enabled, the level of detail can be controlled by the Debug Information Format (DEBUG_INFORMATION_FORMAT) setting.

    Enabling this option will enable increased sharing of precompiled headers among targets that share the same prefix header and precompiled header directory.

    Xcode distinguishes between precompiled header (PCH) files by generating a hash value based on the command-line options to the compiler used to create the PCH. Enabling this option will exclude certain compiler options from that hash. Presently this option will exclude search path options (-I, -iquote, -isystem, -F, -L) from the hash.

    Enabling increased sharing of PCH files carries some risk—if two targets use the same prefix header but have different include paths that cause the prefix header to include different files when they are precompiled, then subtle problems may result because one target will use a PCH that was built using files included by the other target. In this case, this option must be turned off in order to enforce correctness.

    Type Boolean
    Default Value NO
  • Inline Methods Hidden GCC_INLINES_ARE_PRIVATE_EXTERN

    When enabled, out-of-line copies of inline methods are declared private extern.

    Type Boolean
    Default Value NO
  • Compile Sources As GCC_INPUT_FILETYPE

    Specifies whether to compile each source file according to its file type, or whether to treat all source files in the target as if they are of a specific language.

    Type Enumeration
    Values
    • automatic
    • sourcecode.c.c
    • sourcecode.c.objc
    • sourcecode.cpp.cpp
    • sourcecode.cpp.objcpp
    Default Value automatic
  • Instrument Program Flow GCC_INSTRUMENT_PROGRAM_FLOW_ARCS

    Activating this setting indicates that code should be added so program flow arcs are instrumented.

    Type Boolean
    Default Value NO
  • Gcc Macosx Version Min GCC_MACOSX_VERSION_MIN
    Type String
    Default Value $($(DEPLOYMENT_TARGET_SETTING_NAME))
  • No Common Blocks GCC_NO_COMMON_BLOCKS

    In C, allocate even uninitialized global variables in the data section of the object file, rather than generating them as common blocks. This has the effect that if the same variable is declared (without extern) in two different compilations, you will get an error when you link them.

    Type Boolean
    Default Value NO
  • Gcc Objc Abi Version GCC_OBJC_ABI_VERSION
    Type Enumeration

    Default Value compile
  • Optimization Level GCC_OPTIMIZATION_LEVEL

    Specifies the degree to which the generated code is optimized for speed and binary size.

    • None: Do not optimize. -O0 With this setting, the compiler’s goal is to reduce the cost of compilation and to make debugging produce the expected results. Statements are independent—if you stop the program with a breakpoint between statements, you can then assign a new value to any variable or change the program counter to any other statement in the function and get exactly the results you would expect from the source code.

    • Fast: Optimizing compilation takes somewhat more time, and a lot more memory for a large function. -O1 With this setting, the compiler tries to reduce code size and execution time, without performing any optimizations that take a great deal of compilation time. In Apple’s compiler, strict aliasing, block reordering, and inter-block scheduling are disabled by default when optimizing.

    • Faster: The compiler performs nearly all supported optimizations that do not involve a space-speed tradeoff. -O2 With this setting, the compiler does not perform loop unrolling or function inlining, or register renaming. As compared to the Fast setting, this setting increases both compilation time and the performance of the generated code.

    • Fastest: Turns on all optimizations specified by the Faster setting and also turns on function inlining and register renaming options. This setting may result in a larger binary. -O3

    • Fastest, Smallest: Optimize for size. This setting enables all Faster optimizations that do not typically increase code size. It also performs further optimizations designed to reduce code size. -Os

    • Fastest, Aggressive Optimizations: This setting enables Fastest but also enables aggressive optimizations that may break strict standards compliance but should work well on well-behaved code. -Ofast

    • Smallest, Aggressive Size Optimizations: This setting enables additional size savings by isolating repetitive code patterns into a compiler generated function. -Oz

  • Precompile Prefix Header GCC_PRECOMPILE_PREFIX_HEADER

    Generates a precompiled header for the prefix header, which should reduce overall build times.

    Precompiling the prefix header will be most effective if the contents of the prefix header or any file it includes change rarely. If the contents of the prefix header or any file it includes change frequently, there may be a negative impact to overall build time.

    Type Boolean
    Default Value $(PRECOMPILE_PREFIX_HEADER)
  • Prefix Header GCC_PREFIX_HEADER

    Implicitly include the named header. The path given should either be a project relative path or an absolute path.

    Type Path
    Default Value $(PREFIX_HEADER)

    Reuse string literals.

    Type Boolean
    Default Value YES
  • Short Enumeration Constants GCC_SHORT_ENUMS

    Make enums only as large as needed for the range of possible values.

    This setting generates code that may not binary compatible with code generated without this setting or with macOS frameworks.

    Type Boolean
    Default Value NO
  • Enforce Strict Aliasing GCC_STRICT_ALIASING

    Optimize code by making more aggressive assumptions about whether pointers can point to the same objects as other pointers. Programs that use pointers a lot may benefit from this, but programs that don’t strictly follow the ISO C rules about the type with which an object may be accessed may behave unexpectedly.

    Type Boolean
    Default Value YES
  • Symbols Hidden by Default GCC_SYMBOLS_PRIVATE_EXTERN

    When enabled, all symbols are declared private extern unless explicitly marked to be exported using ` attribute ((visibility(“default”))) in code. If not enabled, all symbols are exported unless explicitly marked as private extern`. See Controlling Symbol Visibility in C++ Runtime Environment Programming Guide.

    Type Boolean
    Default Value NO
  • Statics are Thread-Safe GCC_THREADSAFE_STATICS

    Emits extra code to use the routines specified in the C++ ABI for thread-safe initialization of local statics. You can disable this option to reduce code size slightly in code that doesn’t need to be thread-safe.

    Type Boolean
    Default Value YES
  • Treat Missing Function Prototypes as Errors GCC_TREAT_IMPLICIT_FUNCTION_DECLARATIONS_AS_ERRORS

    Causes warnings about missing function prototypes to be treated as errors. Only applies to C and Objective-C.

    Type Boolean
    Default Value NO
  • Treat Incompatible Pointer Type Warnings as Errors GCC_TREAT_INCOMPATIBLE_POINTER_TYPE_WARNINGS_AS_ERRORS

    Enabling this option causes warnings about incompatible pointer types to be treated as errors.

    Type Boolean
    Default Value NO
  • Treat Warnings as Errors GCC_TREAT_WARNINGS_AS_ERRORS

    Enabling this option causes all warnings to be treated as errors.

    Type Boolean
    Default Value NO
  • Unroll Loops GCC_UNROLL_LOOPS

    Unrolls loops. Unrolling makes the code larger, but may make it faster by reducing the number of branches executed.

    Type Boolean
    Default Value NO
  • Use Standard System Header Directory Searching GCC_USE_STANDARD_INCLUDE_SEARCHING

    Controls whether the standard system directories are searched for header files. When disabled, only the directories you have specified with -I options (and the directory of the current file, if appropriate) are searched.

    Type Boolean
    Default Value YES
  • Deprecated Functions GCC_WARN_ABOUT_DEPRECATED_FUNCTIONS

    Warn about the use of deprecated functions, variables, and types (as indicated by the deprecated attribute).

    Type Boolean
    Default Value YES
  • Undefined Use of offsetof Macro GCC_WARN_ABOUT_INVALID_OFFSETOF_MACRO

    Unchecking this setting will suppress warnings from applying the offsetof macro to a non-POD type. According to the 1998 ISO C++ standard, applying offsetof to a non-POD type is undefined. In existing C++ implementations, however, offsetof typically gives meaningful results even when applied to certain kinds of non-POD types, such as a simple struct that fails to be a POD type only by virtue of having a constructor. This flag is for users who are aware that they are writing nonportable code and who have deliberately chosen to ignore the warning about it.

    The restrictions on offsetof may be relaxed in a future version of the C++ standard.

    Type Boolean
    Default Value YES
  • Missing Fields in Structure Initializers GCC_WARN_ABOUT_MISSING_FIELD_INITIALIZERS

    Warn if a structure’s initializer has some fields missing. For example, the following code would cause such a warning because x.h is implicitly zero:

    struct s { int f, g, h; };struct s x = { 3, 4 };

    This option does not warn about designated initializers, so the following modification would not trigger a warning:

    struct s { int f, g, h; };struct s x = { .f = 3, .g = 4 };

    Type Boolean
    Default Value NO
  • Missing Newline At End Of File GCC_WARN_ABOUT_MISSING_NEWLINE

    Warn when a source file does not end with a newline.

    Type Boolean
    Default Value NO
  • Missing Function Prototypes GCC_WARN_ABOUT_MISSING_PROTOTYPES

    Causes warnings to be emitted about missing prototypes.

    Type Boolean
    Default Value NO
  • Pointer Sign Comparison GCC_WARN_ABOUT_POINTER_SIGNEDNESS

    Warn when pointers passed via arguments or assigned to a variable differ in sign.

    Type Boolean
    Default Value YES
  • Mismatched Return Type GCC_WARN_ABOUT_RETURN_TYPE

    Causes warnings to be emitted when a function with a defined return type (not void) contains a return statement without a return-value or when it does not contain any return statements. Also emits a warning when a function with a void return type tries to return a value.

    Type Enumeration
    Values
    • YES
    • NO
    • YES_ERROR
    Default Value NO
  • Incomplete Objective-C Protocols GCC_WARN_ALLOW_INCOMPLETE_PROTOCOL

    Warn if methods required by a protocol are not implemented in the class adopting it. Only applies to Objective-C.

    Type Boolean
    Default Value YES
  • Check Switch Statements GCC_WARN_CHECK_SWITCH_STATEMENTS

    Warn whenever a switch statement has an index of enumeral type and lacks a case for one or more of the named codes of that enumeration. The presence of a default label prevents this warning. Case labels outside the enumeration range also provoke warnings when this option is used.

    Type Boolean
    Default Value YES
  • Four Character Literals GCC_WARN_FOUR_CHARACTER_CONSTANTS

    Warn about four-char literals (for example, macOS-style OSTypes: 'APPL').

    Type Boolean
    Default Value NO
  • Overloaded Virtual Functions GCC_WARN_HIDDEN_VIRTUAL_FUNCTIONS

    Warn when a function declaration hides virtual functions from a base class.

    For example, in the following example, the A class version of f() is hidden in B.

    struct A { virtual void f();};struct B: public A { void f(int);};

    As a result, the following code will fail to compile.

    B* b;b-&gt;f();

    This setting only applies to C++ and Objective-C++ sources.

    Type Boolean
    Default Value NO
  • Inhibit All Warnings GCC_WARN_INHIBIT_ALL_WARNINGS

    Inhibit all warning messages.

    Type Boolean
    Default Value NO
  • Initializer Not Fully Bracketed GCC_WARN_INITIALIZER_NOT_FULLY_BRACKETED

    Warn if an aggregate or union initializer is not fully bracketed. In the following example, the initializer for a is not fully bracketed, but the initializer for b is fully bracketed.

    int a22` = { 0, 1, 2, 3 };int b22 = { { 0, 1 }, { 2, 3 } };`

    Type Boolean
    Default Value NO
  • Missing Braces and Parentheses GCC_WARN_MISSING_PARENTHESES

    Warn if parentheses are omitted in certain contexts, such as when there is an assignment in a context where a truth value is expected, or when operators are nested whose precedence causes confusion. Also, warn about constructions where there may be confusion as to which if statement an else branch belongs. For example:

    { if (a) if (b) foo (); else bar ();}

    In C, every else branch belongs to the innermost possible if statement, which in the example above is if (b). This is often not what the programmer expects, as illustrated by indentation used in the example above. This build setting causes GCC to issue a warning when there is the potential for this confusion. To eliminate the warning, add explicit braces around the innermost if statement so there is no way the else could belong to the enclosing if. For example:

    { if (a) { if (b) foo (); else bar (); }}

    Type Boolean
    Default Value YES
  • Gcc Warn Multiple Definition Types For Selector GCC_WARN_MULTIPLE_DEFINITION_TYPES_FOR_SELECTOR
    Type Boolean
    Default Value NO
  • Nonvirtual Destructor GCC_WARN_NON_VIRTUAL_DESTRUCTOR

    Warn when a class declares an nonvirtual destructor that should probably be virtual, because it looks like the class will be used polymorphically. This is only active for C++ or Objective-C++ sources.

    Type Boolean
    Default Value NO
  • Pedantic Warnings GCC_WARN_PEDANTIC

    Issue all the warnings demanded by strict ISO C and ISO C++; reject all programs that use forbidden extensions, and some other programs that do not follow ISO C and ISO C++. For ISO C, follows the version of the ISO C standard specified by any -std option used.

    Type Boolean
    Default Value NO
  • Hidden Local Variables GCC_WARN_SHADOW

    Warn whenever a local variable shadows another local variable, parameter or global variable or whenever a builtin function is shadowed.

    Type Boolean
    Default Value NO
  • Sign Comparison GCC_WARN_SIGN_COMPARE

    Warn when a comparison between signed and unsigned values could produce an incorrect result when the signed value is converted to unsigned.

    Type Boolean
    Default Value NO
  • Strict Selector Matching GCC_WARN_STRICT_SELECTOR_MATCH

    Warn if multiple methods with differing argument and/or return types are found for a given selector when attempting to send a message using this selector to a receiver of type id or Class. When this setting is disabled, the compiler will omit such warnings if any differences found are confined to types that share the same size and alignment.

    Type Boolean
    Default Value NO
  • Typecheck Calls to printf/scanf GCC_WARN_TYPECHECK_CALLS_TO_PRINTF

    Check calls to printf and scanf to make sure that the arguments supplied have types appropriate to the format string specified, and that the conversions specified in the format string make sense.

    Type Boolean
    Default Value YES
  • Undeclared Selector GCC_WARN_UNDECLARED_SELECTOR

    Warn if a @selector(...) expression referring to an undeclared selector is found. A selector is considered undeclared if no method with that name has been declared before the @selector(...) expression, either explicitly in an @interface or @protocol declaration, or implicitly in an @implementation section. This option always performs its checks as soon as a @selector(...) expression is found, while -Wselector only performs its checks in the final stage of compilation. This also enforces the coding style convention that methods and selectors must be declared before being used.

    Type Boolean
    Default Value NO
  • Uninitialized Variables GCC_WARN_UNINITIALIZED_AUTOS

    Warn if a variable might be clobbered by a setjmp call or if an automatic variable is used without prior initialization.

    The compiler may not detect all cases where an automatic variable is initialized or all usage patterns that may lead to use prior to initialization. You can toggle between the normal uninitialized value checking or the more aggressive (conservative) checking, which finds more issues but the checking is much stricter.

    Type Enumeration
    Values
    • YES
    • YES_AGGRESSIVE
    • NO
    Default Value NO
  • Unknown Pragma GCC_WARN_UNKNOWN_PRAGMAS

    Warn when a #pragma directive is encountered that is not understood by GCC. If this command line option is used, warnings will even be issued for unknown pragmas in system header files. This is not the case if the warnings were only enabled by the -Wall command-line option.

    Type Boolean
    Default Value NO
  • Unused Functions GCC_WARN_UNUSED_FUNCTION

    Warn whenever a static function is declared but not defined or a noninline static function is unused.

    Enabling this setting allows optimization across file boundaries during linking.

    • No: Disabled. Do not use link-time optimization.

    • Monolithic Link-Time Optimization: This mode performs monolithic link-time optimization of binaries, combining all executable code into a single unit and running aggressive compiler optimizations.

    • Incremental Link-Time Optimization: This mode performs partitioned link-time optimization of binaries, inlining between compilation units and running aggressive compiler optimizations on each unit in parallel. This enables fast incremental builds and uses less memory than Monolithic LTO.

  • Base SDK SDKROOT

    The name or path of the base SDK being used during the build. The product will be built against the headers and libraries located inside the indicated SDK. This path will be prepended to all search paths, and will be passed through the environment to the compiler and linker. Additional SDKs can be specified in the Additional SDKs (ADDITIONAL_SDKS) setting.

    Type Path
  • Use Header Maps USE_HEADERMAP

    Enable the use of Header Maps, which provide the compiler with a mapping from textual header names to their locations, bypassing the normal compiler header search path mechanisms. This allows source code to include headers from various locations in the file system without needing to update the header search path build settings.

    Type Boolean
    Default Value YES

  • OpenCL Compiler Version OPENCL_COMPILER_VERSION

    The OpenCL C compiler version supported by the platform.

    Type Enumeration
    Values
    • CL1.2
    • CL1.1
    Default Value CL1.1
  • Flush denorms to zero OPENCL_DENORMS_ARE_ZERO

    This option controls how single precision and double precision denormalized numbers are handled. If specified as a build option, the single precision denormalized numbers may be flushed to zero; double precision denormalized numbers may also be flushed to zero if the optional extension for double precision is supported. This is intended to be a performance hint and the OpenCL compiler can choose not to flush denorms to zero if the device supports single precision (or double precision) denormalized numbers.

    This option is ignored for single precision numbers if the device does not support single precision denormalized numbers, for example, CL_FP_DENORM bit is not set in CL_DEVICE_SINGLE_FP_CONFIG.

    This option is ignored for double precision numbers if the device does not support double precision or if it does support double precision but not double precision denormalized numbers, for example, CL_FP_DENORM bit is not set in CL_DEVICE_DOUBLE_FP_CONFIG.

    This flag only applies for scalar and vector single precision floating-point variables and computations on these floating-point variables inside a program. It does not apply to reading from or writing to image objects.

    Type Boolean
    Default Value NO
  • Double as single OPENCL_DOUBLE_AS_SINGLE

    Treat double precision floating-point expression as a single precision floating-point expression. This option is available for GPUs only.

    Type Boolean

  • Relax IEEE Compliance OPENCL_FAST_RELAXED_MATH

    This allows optimizations for floating-point arithmetic that may violate the IEEE 754 standard and the OpenCL numerical compliance requirements defined in in section 7.4 for single-precision floating-point, section 9.3.9 for double-precision floating-point, and edge case behavior in section 7.5 of the OpenCL 1.1 specification.

    This is intended to be a performance optimization.

    This option causes the preprocessor macro ` FAST_RELAXED_MATH ` to be defined in the OpenCL program.

    Type Boolean
    Default Value NO
  • Use MAD OPENCL_MAD_ENABLE

    Allow a * b + c to be replaced by a mad instruction. The mad computes a * b + c with reduced accuracy. For example, some OpenCL devices implement mad as truncate the result of a * b before adding it to c.

    This is intended to be a performance optimization.

    Type Boolean
    Default Value NO
  • Optimization Level OPENCL_OPTIMIZATION_LEVEL
    • None: Do not optimize. -O0 With this setting, the compiler’s goal is to reduce the cost of compilation and to make debugging produce the expected results. Statements are independent: if you stop the program with a breakpoint between statements, you can then assign a new value to any variable or change the program counter to any other statement in the function and get exactly the results you would expect from the source code.

    • Fast: Optimizing compilation takes somewhat more time, and a lot more memory for a large function. -O, -O1 With this setting, the compiler tries to reduce code size and execution time, without performing any optimizations that take a great deal of compilation time. In Apple’s compiler, strict aliasing, block reordering, and inter-block scheduling are disabled by default when optimizing.

    • Faster: The compiler performs nearly all supported optimizations that do not involve a space-speed tradeoff. -O2 With this setting, the compiler does not perform loop unrolling or function inlining, or register renaming.

XPC Service

XPC Service

  • Enable Exceptions GCC_ENABLE_EXCEPTIONS

    Enable exception handling. Generates extra code needed to propagate exceptions. For some targets, this implies GCC will generate frame unwind information for all functions, which can produce significant data size overhead, although it does not affect execution.
