title: Loading UIViewController "from" Nib File
body: <p>I am trying to create an <code>UIViewController</code> from a Nib file. On Google I found that I can only load an UIView from Nib. </p>
  
  <p>But some suggests that I could create a Nib file (of UIView) whose File Owner is set to our <code>ViewController</code>. </p>
  
  <p>That is what I did, I got no crashes, but the View is just not displayed.</p>
  
  <p>EDIT: 
  Tried to push the <code>viewcontroller</code> like this</p>
  
  <pre><code>self.navigationController!.pushViewController(CoolViewController(), animated: true );
  </code></pre>
  
  <p>But it still showing black screen when it is pushed </p>
