Build an IOS Application Tutorial - Trigger Authentication at Run Time

Hi, still working my way through this tutorial & have worked out that I am on the latest Xcode with IOS 15. Hence some differences. Im trying to add Signin, Signet Code in Module 3 but my build (that succeeds) doesn't have an info.plist file. Wondering where it should go know or should I just create such file?

Thanks in advance
