Kivy for IOS
This toolchain is designed to compile the necessary libraries for iOS to run your application and manage the creation of the Xcode project.
Currently, we do not provide any binary distributions of this toolchain, but we aim to. Until then, you do need to compile it at least once before creating your Xcode project.
The toolchain supports:
- iPhone Simulator (x86 and x86_64)
- iPhone / iOS (armv7 and arm64)
These recipes are not ported to the new toolchain yet:
Currently, the toolchain requires a few tools for compilation. You will need:
Xcode 6 or above, with an iOS SDK and command line tools installed:
Using brew, you can install the following dependencies:
brew install autoconf automake libtool pkg-config brew link libtool
Install Cython (0.21):
# pip method if available (sudo might be needed.) pip install cython==0.21
Using the toolchain
Any Python extensions or C/C++ library must be compiled: you need to have what we call a recipe to compile it. For example, Python, libffi, SDL2, SDL_image, freetype... all the dependencies, compilation and packaging instructions are contained in a recipe.
You can list the available recipes and their versions with:
$ ./toolchain.py recipes freetype 2.5.5 hostpython 2.7.1 ios master kivy ios-poly-arch libffi 3.2.1 pyobjus master python 2.7.1 sdl2 iOS-improvements sdl2_image 2.0.0 sdl2_mixer 2.0.0 sdl2_ttf 2.0.12
Then, start the compilation with:
$ ./toolchain.py build kivy
The Kivy recipe depends on several others, like the sdl* and python recipes. These may in turn depend on others e.g. sdl2_ttf depends on freetype, etc. You can think of it as follows: the kivy recipe will compile everything necessary for a minimal working version of Kivy.
Don't grab a coffee, just do diner. Compiling all the libraries for the first time, 4x over (remember, 4 archs, 2 per platforms), will take time. (TODO: provide a way to not compile for the simulator.).
Create the Xcode project
The toolchain.py can create the initial Xcode project for you:
$ # ./toolchain.py create <title> <app_directory> $ ./toolchain.py create Touchtracer ~/code/kivy/examples/demo/touchtracer
Your app directory must contain a main.py. A directory named <title>-ios will be created, with an Xcode project in it. You can open the Xcode project using:
$ open touchtracer-ios/touchtracer.xcodeproj
Then click on Play, and enjoy.

- You need to install the Command line tools: xcode-select --install
