issue when invoking findObjectsInBackGroundWithBlock() with Parse in iOS

Using Parse in my project, i have this line 

query.findObjectsInBackgroundWithBlock({ (objects:[PFObject], error:NSError) -> Void in      })

But Xcode keeps telling me : 

cannot invoke this method with an argument list `([PFObject],NSError)`.

Any idea why??

Instead of at the end of each parameter having an exclamation point at the end of it, change the ! to a ? So it would be 

query.findObjectsInBackgroundWithBlock({ (objects: [AnyObject]?, error: NSError?) -> Void in

That was what I tried and it seemed to work.

The 2 closure parameters are both optionals, declared as implicitly unwrapped:

query.findObjectsInBackgroundWithBlock({ (objects: [AnyObject]!, error: NSError!) -> Void in
                                                              ^                ^

Also, I think that the first argument should be [AnyObject]! and not [PFObject]! - not sure, so I suggest you to verify that.
