## README

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

### NEW!
* The toolchain now supports the new features introduced in CMake 3.14 that allows combined (FAT libraries) to be built.
    * Please see below for the "COMBINED" options that will build a static, combined FAT library by default.
* The `IOS_PLATFORM` argument have been renamed to `PLATFORM` to better align with how the toolchain will be used.
    * `IOS_PLATFORM` argument still exists, but is deprecated.
* MUCH better support for Xcode generated project on CMake 3.14+

=========

[![Build Status](https://travis-ci.org/leetal/ios-cmake.svg?branch=master)](https://travis-ci.org/leetal/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 10.2.x, iOS SDK 12.2

# Example usage 
**NOTE: The below commands will build for 64-bit simulator only. Change the `-DPLATFORM` to the applicable value if targeting another platform.**

```bash
cd example/example-lib
mkdir build
cd build
cmake .. -G Xcode -DCMAKE_TOOLCHAIN_FILE=../../ios.toolchain.cmake -DPLATFORM=OS64COMBINED
cmake --build . --config Release --target install
```

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

## Options

* Set `-DPLATFORM` to "SIMULATOR" to build for iOS simulator 32 bit (i386) **DEPRECATED**
* Set `-DPLATFORM` to "SIMULATOR64" (example above) to build for iOS simulator 64 bit (x86_64)
* Set `-DPLATFORM` to "OS" to build for Device (armv7, armv7s, arm64)
* Set `-DPLATFORM` to "OS64" to build for Device (arm64)
* Set `-DPLATFORM` to "OS64COMBINED" to build for Device & Simulator (FAT lib) (arm64, x86_64)
* Set `-DPLATFORM` to "TVOS" to build for tvOS (arm64)
* Set `-DPLATFORM` to "TVOSCOMBINED" to build for tvOS & Simulator (arm64, x86_64)
* Set `-DPLATFORM` to "SIMULATOR_TVOS" to build for tvOS Simulator (x86_64)
* Set `-DPLATFORM` to "WATCHOS" to build for watchOS (armv7k, arm64_32)
* Set `-DPLATFORM` to "WATCHOSCOMBINED" to build for watchOS & Simulator (armv7k, arm64_32, i386)
* Set `-DPLATFORM` to "SIMULATOR_WATCHOS" to build for watchOS Simulator (i386)

### COMBINED options
The options called *COMBINED (OS64COMBINED, TVOSCOMBINED and WATCHOSCOMBINED) will build complete FAT-libraries for 
the given platform. These FAT-libraries include slices for both device and simulator, making the distribution and 
usage of the library much more simple!

**NOTE: The COMBINED options _ONLY_ work with the Xcode generator (-G Xcode).** 

### 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

`-DENABLE_STRICT_TRY_COMPILE=(BOOL)` - Disabled by default, specify TRUE or 1 to enable strict compiler checks (will run linker on all compiler checks whenever needed)

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

__*To combine all platforms into the same FAT-library, either build any of the "*COMBINED*" platform types OR use the 
LIPO tool. More information on how to combine libraries with LIPO is readily available on the net.*__

## Thanks To
