A CMake toolchain file for iOS, watchOS and tvOS C/C++/Obj-C++ development

A CMake toolchain file for iOS, watchOS and tvOS development with full simulator support and toggable options!

ios-cmake

Tested with the following combinations:

• XCode 5.x, iOS SDK 7
• XCode 6.1.x, iOS SDK 8.1
• XCode 8.2.x, iOS SDK 10.2
• XCode 9.4.x, iOS SDK 11.4
• XCode 10.0.x, iOS SDK 12.0

Example usage

NOTE: The below commands will build for 64-bit simulator only. Change the -DIOS_PLATFORM to the applicable value if targeting another platform.

cd example/example-lib
mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=../../ios.toolchain.cmake -DIOS_PLATFORM=SIMULATOR64
make
make install

This will build and install the library for the given IOS_PLATFORM.

Options

• Set -DIOS_PLATFORM to "SIMULATOR" to build for iOS simulator 32 bit (i386) DEPRECATED
• Set -DIOS_PLATFORM to "SIMULATOR64" (example above) to build for iOS simulator 64 bit (x86_64)
• Set -DIOS_PLATFORM to "OS" to build for Device (armv7, armv7s, arm64, arm64e)
• Set -DIOS_PLATFORM to "OS64" to build for Device (arm64, arm64e)
• Set -DIOS_PLATFORM to "TVOS" to build for tvOS (arm64)
• Set -DIOS_PLATFORM to "SIMULATOR_TVOS" to build for tvOS Simulator (x86_64)
• Set -DIOS_PLATFORM to "WATCHOS" to build for watchOS (armv7k, arm64_32)
• Set -DIOS_PLATFORM to "SIMULATOR_WATCHOS" to build for watchOS Simulator (x86_64)

Additional Options

-DENABLE_BITCODE=(BOOL) - Enabled by default, specify FALSE or 0 to disable bitcode

-DENABLE_ARC=(BOOL) - Enabled by default, specify FALSE or 0 to disable ARC

-DENABLE_VISIBILITY=(BOOL) - Disabled by default, specify TRUE or 1 to enable symbol visibility support

-DIOS_ARCH=(STRING) - Valid values are: armv7, armv7s, arm64, arm64e, i386, x86_64, armv7k, arm64_32. By default it will build for all valid architectures based on -DIOS_PLATFORM (see above)

The resulting binary will consist of only one platform. To combine all platforms into the same fat-library, use the LIPO tool. More information on this is available on the net.

Thanks To

• natbro for adding tvOS support
• MSNexploder for adding OS64 and arm64e support
• garryyan for adding watchOS support
