How to send my score variable to another view controller?

After I click on a button I go to a new view controller.

I made it possible to make points with var score = 0 in a IBOutlet and to show to points I use Score.text = "\(++score)".

How can I pass the score to the 'Game over' screen/view controller to a label called "resultScore"?

Add an attribute secondViewController in the destination view controller, and use prepareForSegue

Current View Controller

   override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
          if (segue.identifier == "segueTest") {
               var svc = segue!.destinationViewController as secondViewController;

               svc.toPass = textField.text

           }
        }

in secondViewController you can define one variable like String

    var toPass:String!

In the secondViewController under the viewDidLoad function add this code

    println(\(toPass))

FirstViewController

@IBOutlet weak var textField: UITextField!

...

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if let vc = segue.destinationViewController as? GameOverViewController {
        vc.score = Int(textField?.text)
    }
}

...

SecondViewController

var score: Int!
@IBOutlet weak var label: UILabel!

... 

override func viewDidLoad() {
    super.viewDidLoad()
    label.text = String(score)
}

This method will call when button was pressed, and in this place you may set some properties for your second view controller

One easy way to achieve that is you can use NSUserDefault for that.

first of all in your playScene when you are increasing your score you can store your score this way:

Score.text = "\(++score)"
NSUserDefaults.standardUserDefaults().setInteger(score, forKey: "userScore")

After that in your next view controller you can get score this way:

resultScore = NSUserDefaults.standardUserDefaults().integerForKey("userScore")

Remember that type of your resultScore should be Int.
