title: Storyboard uiviewcontroller, 'custom class' not showing in drop down
body: <p>I have a UIViewController I created in my apps storyboard, as well as a custom UIViewController subclass which I added to the project (and is correctly in the compile phase for my target). However when I go to set the 'Custom Class' property on the view-controller in Storyboard my custom class does not show up on the list.</p>
  
  <ul>
  <li>Checked that the class is part of my app's target, not tests'</li>
  <li>Double checked that it is correctly a subclass of UIViewController</li>
  <li>Compiled program just to make sure xcode was working with latest information</li>
  <li>Restarted xcode</li>
  </ul>
  
  <p>What would cause my class to not show up in the 'Custom Class' drop down?</p>
