Forgive me, Brian, however, the version of the project already includes push notifications and I'm yet to register with APPLE Devs license. From my past experiences, `prior to the recent download of the course source code, the app was working fine from source code. Frankly, man, I can't even begin to think straight on which line could be causing this, if it's only one line...
AppDelegate is only calling: (in regards to this)
window = UIWIndow()
window?.rootViewController = mainTabBarController()
login Method in the loginVC
is pretty much the same, except for the Strings, Firebase auth syntax(using swift 3.2 - if that makes a difference) and thats it...
