title: Use PKRevealController with Swift
body: <p>I'm trying to add PKRevealController to my Swift Project but it doesn't work. I think this is the problem: </p>
  
  <p><strong>Setup</strong></p>
  
  <ol>
  <li><p>Instantiate.</p>
  
  <p>PKRevealController *revealController = [PKRevealController revealControllerWithFrontViewController:front leftViewController:left];</p></li>
  <li><p>Configure.</p>
  
  <p>revealController.delegate = self;</p></li>
  <li><p>Apply.</p>
  
  <p>self.window.rootViewController = revealController;</p></li>
  </ol>
  
  <p>(<a href="https://github.com/pkluz/PKRevealController/blob/master/Documentation/USAGE.md" rel="nofollow">Source of the PKRevealController</a>)</p>
  
  <p>I cannot translate this Objective C to Swift without getting an error. 
  PKRevealController was added by CocoaPods.</p>
