Here is the simple solution for this.

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    if (url.absoluteString.range(of: "oauth2callback") != nil) {
       GPPSignIn.sharedInstance().handle(url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: nil)
    }
   return false
