firebase-ios-sdk: Google sign in with the Firebase iOS 5.0 pods no longer works.

• Xcode version: 9.3.1
• Firebase SDK version: 5.0.0
• Firebase Component: Auth
• Component version: 5.0.0

I just updated my pods and migrated all my API’s to the Firebase iOS 5.0 API and Google Sign In no longer works. Following the Firebase iOS guide setting the GIDSignIn client ID GIDSignIn.sharedInstance().clientID = FirebaseApp.app()?.options.clientID causes a crash due to an unrecognized selector.
