title: Show view controller from main storyboard
body: <p>I have a <code>case</code> in one of my Swift files which runs the following method:</p>
  
  <pre><code>     case .editProfile:
          vc = PoiDetailViewController()
          self.navigationController?.popViewController(vc,animated: true)
  </code></pre>
  
  <p>It doesn't seem to work when I run the code.</p>
  
  <p>The view controller is located on the main storyboard and I would like <code>PoiDetailViewController</code> to display when this case is called.</p>
