I’m trying to use the pyatv library with PythonKit in my iOS app, but I’m running into several issues. I’m currently facing problems with the cryptography module, specifically with the Rust components. Here is the error message I’m receiving:

I understand that the binary seems to be generated for macOS instead of iOS, but I’m not sure how to generate it for iOS. Has anyone successfully used pyatv with PythonKit on iOS? Any guidance on resolving these issues would be greatly appreciated!
