Cast from '[PFObject]' to unrelated type 'int' always fails [Swift]

Question

I'm trying to put into a variable my PFObject (I'm using Parse):

func retrieveScore() {


    var query:PFQuery = PFQuery(className: "Score")


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


        for varScore in objects! {
            let scoreExtract:Int? = (varScore as? [PFObject]) as? Int
        }
    }
}

But it gives to me this error: "Cast from '[PFObject]' to unrelated type 'int' always fails.

How can I extract the object into a variable? I need an array?

thank you.

What you are doing is first converting varScore to an Array of PFObject and then converting that Array to an Int. How can you convert an Array to Int?

If objects contains Array of PFObject then,

func retrieveScore() {
   var query:PFQuery = PFQuery(className: "Score")
   query.findObjectsInBackgroundWithBlock { (objects:[AnyObject]?, error:NSError?) -> Void in

      for varScore in objects! {
          let score = varScore as? PFObject
          let youeIntPropertyValue = score.someIntProperty// a property in Score class/struct.
      }
   }
}

@Admit89 I can't understand what I have to write here: let youeIntPropertyValue = score.someIntProperty – Luca Alberto May 13 '15 at 18:14
I don't know the integer property inside the Score class. From reader's point of view i just wrote. You need to replace it with your Int property. – Amit89 May 13 '15 at 18:17
can you do an example of what an Int property should be? Score class contain Int value! can you please do me an example by write some codeline? – Luca Alberto May 13 '15 at 18:20
Can you post your Score class here? – Amit89 May 13 '15 at 18:23
var playerScore:PFObject = PFObject(className: "Score") playerScore["Player1"] = 1 playerScore.saveInBackgroundWithBlock { ... – Luca Alberto May 13 '15 at 18:27
@Admit89 you mean that class right? You have enough information? – Luca Alberto May 13 '15 at 18:33
No, from your above code may be you need to do like score["Player1"] or score.Player1 – Amit89 May 13 '15 at 18:49
let youeIntPropertyValue = score["Player1"] or let youeIntPropertyValue = score.Player1 – Amit89 May 13 '15 at 18:54
