title: Swift - alert action handler error
body: <p>I have some strange stuff going on: trying to track if a share action was cancelled in UIAlertAction handler with FLurry Analytics SDK. The code should basically look like that:</p>
  
  <pre><code>       let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: {
              (action:UIAlertAction!) -&gt; Void in
              Flurry.logEvent("Share Cancelled")
              }
          )
  </code></pre>
  
  <p>But compiler shows an error "Extra argument "title" in call..." and highlights "Cancel" in red.
  Though if I add any variable declaration or simple function like println() than there is no error! i.e. this code is compiled correctly and considered to be working:</p>
  
  <pre><code>       let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: {
              (action:UIAlertAction!) -&gt; Void in
              let somevar = 0
              Flurry.logEvent("Share Cancelled")
              }
          )
  </code></pre>
  
  <p>Have anyone faced a thing like that? Maybe it's a Swift or Flurry bug?</p>
