I\'m trying to implement google+ and facebook sign ins in the same app. I followed the instructions by Parse and Google and I first successfully implemented Facebook login.
You need to combine them. The simplest way is to use an || on the return statement. Try this:
func application(application: UIApplication,
openURL url: NSURL, options: [String: AnyObject]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String, annotation: nil) ||
GIDSignIn.sharedInstance().handleURL(url,
sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String,
annotation: options[UIApplicationOpenURLOptionsAnnotationKey] as? String)
}
