AppDelegate show many Error

[bhayangkara]

In sheet 4. Create Firebase console Project.

when i Configure Firebase in AppDelegate. so many error.
for example
line 24 -> mistake message (Cannot find type 'GIDSignInDelegate' in scope)
line 51 -> Cannot find 'FirebaseApp' in scope
line 52-> Value of type 'GIDSignIn' has no member 'delegate'

I was struggling with a similar issue. While I'm not sure what to do with your FirebaseApp problem, I was able to resolve the AppDelegate issues by following these instructions: https://developers.google.com/identity/sign-in/ios/quick-migration-guide

As for the "Value of type 'GIDSignIn' has no member 'delegate'" issue, I honestly just commented out that line and I was able to build the project! No clue if that's what I was SUPPOSED to do though.
