HELP! Error with Google Sign In when following tutorial Firebase!

Hello All, I have a question on how to fix an error in my AppDelegate class that I had to make due to it not existing in Xcode 12. I had made this, and when I am more than halfway through the tutorial on how to make this with “Google Signing In” capabilties. The error is in line 51 in my SMKApp.swift file. It gives me 2 errors:

1: Cannot assign value of type ‘(Optional, _)’ to type ‘String’

2: Value of type ‘GIDGoogleUser’ has no member ‘email’

Thanks, Harri
