Hi! You can run libtorch (C++) on iOS: https://pytorch.org/mobile/ios/, which means you would have to export your model code with e.g. TorchScript (https://pytorch.org/docs/stable/jit.html) and implement a custom inference loop in your iOS app. I'm not very familiar with any tools that let you run python on iOS, a few are mentioned here though: https://www.python.org/download/other/.
