Since Swift can not talk to C++ directly, we have to either use an Objective-C class as a bridge, or create a C wrapper for the C++ library. For demo purpose, we're going to wrap everything in this Objective-C class. However, we're working on providing the Swift/Objective-C API wrappers to PyTorch. Stay tuned!

### API Docs

Currently, the iOS framework uses the Pytorch C++ front-end APIs directly. The C++ document can be found [here](https://pytorch.org/cppdocs/). To learn more about it, we recommend exploring the [C++ front-end tutorials](https://pytorch.org/tutorials/advanced/cpp_frontend.html) on PyTorch webpage.
