title: Cannot connect View Controller to Swift file
body: <p>I created a second view controller in the storyboard. I also created a new Swift-file with <code>File - New - Cocoa....</code>. Now I want to associate that Swift-file with the second view controller. So I highlight the second view controller, and click <code>Show Identity Inspector</code>. In <code>Custom Class</code> in the <code>Class</code> field I normally would add the Swift-file in order to create i.e. outlets. However, I cannot find the newly created Swift-file in there. </p>
  
  <p>Thats the code from the new Swift-file</p>
  
  <pre><code>import UIKit
  
      class EditImageViewController: NSObject {
  
  }
  </code></pre>
  
  <p>Why is that?</p>
