There's a lot of code here, and it's hard to read it and point out a mistake. When you run this code, it's the call tomFirebaseAuth?.signInWithCredential(credential)that will sign the user in to Firebase with their established Google auth credentials. Did you run this code in a debugger to see if it ends up at that line?

There's a lot of code here, and it's hard to read it and point out a mistake. When you run this code, it's the call tomFirebaseAuth?.signInWithCredential(credential)that will sign the user in to Firebase with their established Google auth credentials. Did you run this code in a debugger to see if it ends up at that line?
