But what is the name of the process we need to do in order to validate the JWT? Because the libraries have a lot of functionality and there is no documentation from Apple to know where to start. Some libraries requires a "public key", another libraries requires a "private key", some methods requires a "passphrase", where do I get those things from the Apple?

After doing a lot of research, finally I developed a working solution: https://stackoverflow.com/a/72638944/3701102

I have the same issue using Xcode 14.0.1, I downloaded Xcode 13 and it didn't work either. Only debugging with a physical device works
