Error updating a cell with data from Parse

Question

In Parse I have a class called "Shouts", with a string value called "wall"

I need to see how many "Shouts" I have in every "wall" using a Label inside a cell of my tableview

In my TableviewCell I have:

@IBOutlet var newWallLabel: UILabel!  // the name of the wall (cell is working)
@IBOutlet var shoutCounter: UILabel!  // using this label I want to show the number of objects I have in my "Shouts" class with the same newWallLabel (that is my "wall" String in my Shouts Class)

In my TableView I'm using countObjectsInBackgroundWithBlock. With println works, it show me the number of value I have for this "testing" String in my Shout class in Parse. But what I need is actually to use whatever text will have my newWallLabel UILabel

So I've been trying for a while to connect this "(count)" to my shoutCounter label, creating in my TableView:

  var counter:UILabel!

then this var inside the func that load all the data of the wall

       var countShout = PFQuery(className: "Shouts")
    countShout.whereKey("wall", containsString: "testing")
            countShout.countObjectsInBackgroundWithBlock { (count, _) -> Void in
                if count == 0 {
                    println("No Shouts")
                } else {
                    self.counter.text = "\(count)"
                }
    }

then when configuring my cell I've used

        cell.shoutCounter.text = counter.text

Everything looks fine without errors, but when I build the app it crash with a "fatal error: unexpectedly found nil while unwrapping an Optional value" pointing at this string

        cell.shoutCounter.text = counter.text

What I'm missing?

I can't comment on questions yet, but counter is nil because you haven't initialized it to any value. If it exist on your storyboard, then it shouldn't be nil. Perhaps you can try to recreate the IBOutlet

If you are trying to define the label programmatically, check out the sample code for defining a UILabel.

var label:UILabel!
label = UILabel(frame: CGRectMake(0, 0, 200, 21))
label.center = CGPointMake(160, 284)
label.textAlignment = NSTextAlignment.Center
label.text = "I'am a test label"
self.view.addSubview(label)

I hope this helps.
