title: UIStoryboard Couldn't find view controller with identifier
body: <p>I have an ios application using storyboards with a bunch of view controllers.</p>
  
  <p>After Adding a new ViewController, and configured the identify (Storyboard ID)
  <img src="https://i.stack.imgur.com/vSYV3.png" alt="enter image description here"></p>
  
  <p>I try to instantiate the new ViewController with the following code:</p>
  
  <pre><code>SurveyNewViewController *newSurvey = [[self storyboard] instantiateViewControllerWithIdentifier:@"newSurveyView"];
  [self presentViewController:newSurvey animated:YES completion:nil];
  </code></pre>
  
  <p>Everything seems to be right, but when running the application on the simulator it crashes:</p>
  
  <pre><code>** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:   
  'Storyboard (&lt;UIStoryboard: 0xa340fa0&gt;) doesn't contain a view controller 
  with identifier 'newSurveyView''
  </code></pre>
  
  <p>Is there any possible explanation for this? I have used this same approach in different places on the system and it works well.</p>
