addChild after 2 seconds

I'm trying to addChild after 2 seconds the user touched the screen (it is inside touchesBegan), but it doesn't work. Am I doing anything wrong?

//show myLabel after 2 seconds
self.myLabel.position = CGPoint(x: self.frame.width / 1.1, y: self.frame.height / 2)
self.myLabel.text = "0"
self.myLabel.zPosition = 4

self.myLabel.runAction(SKAction.sequence([SKAction.waitForDuration(2.0), SKAction.runBlock({
    self.addChild(self.myLabel)
)]))

You can declare this function, where you want

public func delay(delay:Double, closure:()->()) {
    dispatch_after(
        dispatch_time(
           DISPATCH_TIME_NOW,
           Int64(delay * Double(NSEC_PER_SEC))
        ),
        dispatch_get_main_queue(), closure)
 }

and using as:

   delay(2.0) {
      self.addChild(self.myLabel)
   }

The problem is that the actions won't run on myLabel unless it is in the scene, so change the last part into :

self.runAction(SKAction.sequence([SKAction.waitForDuration(2.0), SKAction.runBlock({
    self.addChild(self.myLabel)
})]))

Or better:

self.runAction(SKAction.waitForDuration(2)) {
    self.addChild(self.myLabel)
}

Note: I assume here that self is a scene or some other node that is already added to the scene.
