title: Swift setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key
body: <p>I removed manually from my Xcode project <strong>Alamofire POD</strong> and since this time, I have errors in some <code>UIViewControllers</code> on any <code>UIButton</code> <code>IBOutlet</code> added.</p>
  
  <p>I have the following error:</p>
  
  <blockquote>
    <p>Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[
    setValue:forUndefinedKey:]: this class is not key value
    coding-compliant for the key btListOrdo</p>
  </blockquote>
  
  <p>I tried to create a new <code>UIViewController</code> and link it to my <code>StoryBoard</code> but I have the same error....</p>
  
  <p>I'm adding the following <code>IBOutlet</code></p>
  
  <pre><code>@IBOutlet weak var btListOrdo: UIButton!
  </code></pre>
  
  <p>Notice that those links worked properly before the POD removal, I may have removed something mandatory but I'm not able to find it.</p>
  
  <p>here is the screenshot of the referencing outlets of my button:</p>

  <p>I also tried to clean the project, cleaned the Build Folder, deleted Derived Data, Reset Content and Settings of the simulator but same result... </p>
