I don't know why this isn't working my Firebase is configured. Here is a Screenshot of my AppDelegate.swift file. Here is my console log:

I have tried all afternoon to get this working. Please help.

Looking in your stack trace, I get the impression you might be accessing the Firebase.Auth class too soon — maybe in the initWithCoder of your VC? Or as a VC property initial value? — which could be before your AppDelegate runs (and initializes Firebase).
As such, try moving your Auth.auth() call to the viewDidLoad method instead to see if it makes a difference at all.
