Twitter logInWithCompletion or logInWithViewController not doing anything

Question

I am trying to login to user's Twitter account. I have followed the guide at https://dev.twitter.com/twitterkit/ios/installation to integrate Twitter.

However, when I try to login, nothing happens:

[[Twitter sharedInstance] logInWithCompletion:^(TWTRSession * _Nullable session, NSError * _Nullable error) {
      //not called
       if(session && !error){

       }else{

       }
 }];

I've also tried specifying view controller explicitly:

[[Twitter sharedInstance] logInWithViewController:self completion:^(TWTRSession * _Nullable session, NSError * _Nullable error) {
   //again, not called.
   if(session && !error){

   }else{

   }
}];

Twitter app itself is logged in and perfectly working with my account.

What am I doing wrong?

UPDATE: I've also tried on simulator (which, obviously, doesn't have the Twitter app) in addition to device (which has the Twitter app and a logged in account), it's the same on both scenarios.

Answer 1

Okay I've figured out the problem. I was mishandling UIApplication openURL:options:completionHandler: method. My app was silently discarding the callback URL request. I've added a case for twitterauth scheme and now it works perfectly.
