title: Error: 'Type of expression is ambiguous without more context'
body: <p>I'm pretty new to coding Swift, so please excuse me if this error is a simple answer! </p>
  
  <p>I keep getting an error message that says "Type of expression is ambiguous without more context."</p>
  
  <pre><code>    var findTimelineData: PFQuery = PFQuery(className: "Sweets")
      findTimelineData.findObjectsInBackgroundWithBlock {
          (objects:[AnyObject]?, error:NSError?) -&gt; Void in
  
          if error == nil {
              for object:PFObject in objects! { // ----This is the error line---
                  self.timelineData.addObject(object)
              }
          }
      }
  </code></pre>
  
  <p>Any suggestions?</p>
  
  <p>Thanks!</p>
