First of all need to say that i don\'t use CocoaPods. And it\'s first time when i use Google API.
In Google guide says that i need to configure GIDSignIn in

Answer 1

remove this line from didFinishLaunch GIDSignIn.sharedInstance().delegate = self

and in your view controller class implement GIDSignInDelegate, GIDSignInUIDelegate protocolos

and in your view controller viewDidload method write this

func viewDidLoad() {
    GIDSignIn.sharedInstance().delegate = self
    GIDSignIn.sharedInstance().uiDelegate = self
}

and don't forget to handle url in app delegate.

func application(application: UIApplication,
               openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {

var flag: Bool = false

// handle Facebook url scheme
if let wasHandled:Bool = FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation) {
  flag = wasHandled
}

if let googlePlusFlag: Bool = GIDSignIn.sharedInstance().handleURL(url, sourceApplication: sourceApplication!, annotation: annotation) {
  flag = googlePlusFlag
}

return flag
}
