Use of unresolved identifier using an alert.addAction

I'm getting an error on my alert.addAction(). Seems like my project doesn't know where to find it, am I right?

I made an alert without buttons, now I'm trying to add buttons to it.

So this is my alert window and the code to add the buttons:

func naamInModelChangedHandler ( notification:NSNotification ) {
    println("De naam in de model is veranderd naar \(model.naam!)")
    NSNotificationCenter.defaultCenter().removeObserver(
                self,
                name: "NAAM_CHANGED",
                object: model)

    let alert = UIAlertController(title: "Ola", message: "De naam is gewijzigd", preferredStyle: UIAlertControllerStyle.Alert)

    self.presentViewController(alert, animated: true, completion: nil)

    alert.addAction(okAction)
    alert.addAction(cancelAction)

}

I've made a UIAlertAction with the name AlertController with some code to make the buttons.

let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default) { (action) -> Void in
    println("Ok geklikt")
}
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) { (action) -> Void in
    println("Cancel geklikt")
}

But it seems it doesn't know where to look for I think. What am I doing wrong here?

Do like this

func naamInModelChangedHandler ( notification:NSNotification ) {
    println("De naam in de model is veranderd naar \(model.naam!)")
    NSNotificationCenter.defaultCenter().removeObserver(
                self,
                name: "NAAM_CHANGED",
                object: model)

   let alert = UIAlertController(title: "Ola", message: "De naam is gewijzigd", preferredStyle: UIAlertControllerStyle.Alert)

    self.presentViewController(alert, animated: true, completion: nil)

   let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default) { (action) -> Void in

    println("Ok geklikt")
   }

  let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) { (action) -> Void in

    println("Cancel geklikt")
  }

    alert.addAction(okAction)
    alert.addAction(cancelAction)

}
