title: Parse load Images Swift 3.0
body: <p>I'm runnig my own parse server and all works fine but 
  I can't convert A PFFile to a UIImage, this is the error it throws at me:</p>
  
  <blockquote>
    <p>Cannot convert value of type '(NSData?, NSError?) -> Void' to expected argument type PFDataResultBlock'</p>
  </blockquote>
  
  <p>Here is the code I used:</p>
  
  <pre><code>var imageFromParse = object.object(forKey: "ProfilePicture") as! PFFile!
                          imageFromParse!.getDataInBackgroundWithBlock({ (imageData: NSData?, error: NSError?) -&gt; Void in
                              var image: UIImage! = UIImage(data: imageData!)!
                          })
  </code></pre>
  
  <p>And all of this used to work perfectly in Swift 2.3.
  thank you for the help.</p>
