title: Xcode 6 Storyboard Unwind Segue with Swift Not Connecting to Exit
body: <p>When trying to connect a Navigation Bar Button to the Exit item of a ViewController in Xcode 6 (not really sure if it's an Xcode 6 problem but worth mentioning as it is in beta) it does not find the Swift function in the custom class.</p>
  
  <p><img src="https://i.stack.imgur.com/x2CBT.png" alt="Button to Exit with whip"></p>
  
  <p>The function it should be finding:</p>
  
  <pre><code>@IBAction func unwindToList(segue: UIStoryboardSegue) {
  
  }
  </code></pre>
  
  <p>I made another button on the view just to make sure I could get an IBAction working with Swift and that I was writing it correctly. This works fine:</p>
  
  <pre><code>@IBAction func test(sender: AnyObject) {
  
      NSLog("Test")
  }
  </code></pre>
  
  <p>I have seen <a href="https://stackoverflow.com/questions/12792573/cannot-connect-storyboard-unwind-segue">this question</a> that seems like the same issue but according to the answers there this should be working.</p>
  
  <p>Xcode 6 is in beta and, of course, Swift is very new, but wanted to see if anyone has come across this before considering it a potential bug. </p>
