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
