Desidero effettuare l'accesso automatico all'utente se è già firmato e basta andare alla vista principale ma il codice è in esecuzione due volte e si può vedere la transistione invece della vista che mostra. Come lo aggiusto?Swift: accesso automatico utente con Firebase
AppDelegate.swift
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.slideMenuController
FIRApp.configure()
FIRAuth.auth()?.addAuthStateDidChangeListener {
auth, user in
if user != nil {
// User is signed in.
print("Automatic Sign In: \(user?.email)")
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewController = storyboard.instantiateViewControllerWithIdentifier("EmployeeRevealViewController")
self.window!.rootViewController = initialViewController
} else {
// No user is signed in.
}
}
return true
}

hai registrato i dati di autenticazione? – Shubhank
segui questo documento da firebase: https://firebase.google.com/docs/auth/ios/google-signin#2_implement_google_sign-in –
