No success/failure callbacks to ASAuthorizationController delegates after apple sign in

I have implemented apple sign in as per the doc. When I sign in with an Apple ID by providing password, it spins for a while and the password sheet gets dismissed. I don't get callbacks to success/failure functions of ASAuthorizationController delegate. I tried in simulator as well as iPhone. Would really appreciate any pointers at what might be wrong here.

Have you managed to resolve the issue? I had similar problem with not getting callback in delegate after calling ASAuthorizationController.performRequest(). Apparently my security key is not showing signal.
