We do not provide any binary distributions of this toolchain. You do need to compile it at least once before creating your Xcode project. The toolchain supports: - iPhone Simulator (x86_64) - iPhone / iOS (armv7 and arm64) These recipes are not ported to the new toolchain yet: - lxml ## Installation & requirements Before we start, we strongly advise to use a Python virtual environment to install Python packages. python3 -m venv venv . venv/bin/activate Install [Kivy for iOS from PyPI](https://pypi.org/project/kivy-ios) with pip like any Python package. pip3 install kivy-ios Additionally you would need few system dependencies and configuration. - Xcode 10 or above, with an iOS SDK and command line tools installed: xcode-select --install - Using brew, you can install the following dependencies: brew install autoconf automake libtool pkg-config brew link libtool ## 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 recipes audiostream master click 7.1.2 cymunk master ffmpeg 2.6.3 ffpyplayer v3.2 flask 1.1.2 freetype 2.5.5 hostlibffi 3.2.1 hostpython3 3.7.1 ios master itsdangerous 1.1.0 jinja2 2.11.2 kivy 1.10.1 libffi 3.2.1 libjpeg v9a libpng 1.6.26 markupsafe 1.1.1 moodstocks 4.1.5 numpy 1.16.4 openssl 1.0.2k photolibrary master pillow 6.1.0 plyer master pycrypto 2.6.1 pykka 1.2.1 pyobjus master python3 3.7.1 pyyaml 3.11 sdl2 2.0.8 sdl2_image 2.0.0 sdl2_mixer 2.0.0 sdl2_ttf 2.0.12 werkzeug 1.0.1 Then, start the compilation with: $ toolchain build python3 kivy You can build recipes at the same time by adding them as parameters: $ toolchain build python3 openssl kivy Recipe builds can be removed via the clean command e.g.: $ toolchain clean openssl You can install package that don't require compilation with pip:: $ toolchain pip install plyer 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, 3x over (remember, 3 archs, x86_64, armv7, arm64) will take time. For a complete list of available commands, type: $ toolchain ## Create the Xcode project The `toolchain.py` can create the initial Xcode project for you:: $ toolchain create <app_directory> $ toolchain 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. > *Did you know ?* > > Everytime you press `Play`, your application directory will be synced to > the `<title>-ios/YourApp` directory. Don't make changes in the -ios > directory directly. ## Configuring your App You can configure and customize your app in various ways: - Set the icon and launch images in XCode. Note that XCode requires that you specify these assests per device or/and iOS version. - When you first build your XCode project, a 'main.m' file is created in your XCode project folder. This file configures your environment variables and controls your application startup. You can edit this file to customize your launch environment. - Kivy uses SDL, and as soon as the application starts the SDL main, the launch image will disappear. To prevent that, you need to have 2 files named `Default.png` and `Default-Landscape.png`, and put them in the `Resources` folder in Xcode (not in your application folder) > *Did you know ?* > > If you wish to restrict your apps orientation, you should do this via > the 'export_orientation' function in 'main.m'. The XCode orientation > settings should be set to support all. ## Using recipes Recipes are used to install and compile any libraries you may need to use. These recipes follow the same format as those used by the [Python-for-Android](https://github.com/kivy/python-for-android) sister project. Please refer to the [recipe documentation](https://python-for-android.readthedocs.io/en/latest/recipes/) there for more detail. ## Reducing the application size If you would like to reduce the size of your distributed app, there are a few things you can do to achieve this: - Minimize the `build/pythonX/lib/pythonXX.zip`: this contains all the python modules. You can edit the zip file and remove all the files you'll not use (reduce encodings, remove xml, email...) - Go to the settings `panel` > `build`, search for `"strip"` options, and triple-check that they are all set to `NO`. Stripping does not work with Python dynamic modules and will remove needed symbols. - By default, the iOS package compiles binaries for all processor architectures, namely x86_64, armv7 and arm64 as per the guidelines from Apple. You can reduce the size of your ipa significantly by removing the x86_64 architecture as they are used only for the emulator. The procedure is to first compile/build all the host recipes as is: toolchain build hostpython3 Then build all the rest of the recipes using --arch=armv7 --arch=arm64 arguments as follows: toolchain build python3 kivy --arch=armv7 --arch=arm64 Note that these packages will not run in the iOS emulators, so use them only for deployment. ## Usage ``` toolchain <command> [<args>] Available commands: build Build a recipe (compile a library for the required target architecture) clean Clean the build of the specified recipe distclean Clean the build and the result recipes List all the available recipes status List all the recipes and their build status Xcode: create Create a new xcode project update Update an existing xcode project (frameworks, libraries..) launchimage Create Launch images for your xcode project icon Create Icons for your xcode project pip Install a pip dependency into the distribution pip3 Install a pip dependency into the python 3 distribution ``` ## Development Alternatively, it's also possible to clone the repository and use all the described commands in the above sections. Clone and install it to your local virtual environment: git clone https://github.com/kivy/kivy-ios.git cd kivy-ios/ python3 -m venv venv . venv/bin/activate pip install -e . Then use the `toolchain.py` script: python toolchain.py --help ## FAQ ### Fatal error: "stdio.h" file not found You need to install the Command line tools: `xcode-select --install` ### You must build with bitcode disabled (Xcode setting ENABLE_BITCODE should be No). We don't support bitcode. You need to go to the project setting, and disable bitcode. ### You don't have permissions to run It is due to invalid archs, search for them and check it. Maybe you targetted a simulator but have only armv7/arm64. Maybe you want to target your iPad but it as only x86_64. ### Why does the python multiprocess/subprocess module not work? The iOS application model does not currently support multi-processing in a cross-platform compatible way. The application design focuses on minimizing processor usage (to minimize power consumption) and promotes an [alternative concurrency model](https://developer.apple.com/library/archive/documentation/General/Conceptual/ConcurrencyProgrammingGuide/Introduction/Introduction.html). If you need to make use of multiple processes, you should consider using [PyObjus](https://github.com/kivy/pyobjus) to leverage native iOS functionals for this. ## Support If you need assistance, you can ask for help on our mailing list: * User Group : https://groups.google.com/group/kivy-users * Email : kivy-users@googlegroups.com We also have a Discord channel: * Server : https://chat.kivy.org * Channel : #support ## Contributing We love pull requests and discussing novel ideas.
