FAQ

Fatal error: "stdio.h" file not found

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

Error: SDK "iphonesimulator" cannot be located

Xcode path is not set up correctly. Run the following command to fix this: sudo xcode-select --switch <YOUR_XCODEAPP_PATH> (Change <YOUR_XCODEAPP_PATH> to the path that reflects your XCode installation, usually is /Applications/Xcode.app)

Bitcode is partially supported now (Xcode setting ENABLE_BITCODE can be set to Yes).

• Supported recipes: python3, kivy, sdl2, sdl2_image, sdl2_mixer, and libffi

You don't have permissions to run

It is due to invalid archs, search for them and check it. Maybe you targeted a simulator but have only arm64. Maybe you want to target your iPad but it is 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.

If you need to make use of multiple processes, you should consider using PyObjus to leverage native iOS functionals for this.
