title: Cannot compose tweets with Twitter Kit 3
body: <p>I followed instruction from <a href="https://dev.twitter.com/twitterkit/ios/compose-tweets" rel="nofollow noreferrer">https://dev.twitter.com/twitterkit/ios/compose-tweets</a> to compose tweets via my Object C app for iOS 11</p>
  
  <pre><code>// Objective-C
  TWTRComposer *composer = [[TWTRComposer alloc] init];
  
  [composer setText:@"just setting up my Twitter Kit"];
  [composer setImage:[UIImage imageNamed:@"twitterkit"]];
  
  // Called from a UIViewController
  [composer showFromViewController:self completion:^(TWTRComposerResult result) {
      if (result == TWTRComposerResultCancelled) {
          NSLog(@"Tweet composition cancelled");
      }
      else {
          NSLog(@"Sending Tweet!");
      }
  }];
  </code></pre>
  
  <p>However, after clicking Connect button at [Connect your account] screen, it turned back app without composing tweet (Twitter logged in already).
  It seems showFromViewController didn't run.
  Anyone had the same problem?</p>
