SpriteKit: node Y position and touch Y position are not consistent

Brand new to SpriteKit and iOS in general. I am following a very simple SpriteKit tutorial and noticed that the Y position of the node is not the same as the Y position of the touch when it touched the same spot as the node. For example:

import SpriteKit

class GameScene: SKScene {

  override func didMoveToView(view: SKView) {
    // add a text label at X: 100 and Y: 100
    let labelNode = SKLabelNode(text: "X:100 Y:100")
    labelNode.position.x = 100
    labelNode.position.y = 100
    labelNode.fontSize = 20.0
    addChild(labelNode)
  }

  override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    // for each touch, print the X and Y positions
    for touch: AnyObject in touches {
      println("You touched at X: \(touch.locationInView(self.view!).x) and Y: \(touch.locationInView(self.view!).y)")
    }
  }

}

      

        
        
        
      

    

This adds text at X: 100 and Y: 100 that is at the bottom left of the scene (using the default scene.anchorPoint

). And when you touch, it prints X and Y where you touched.

The weird thing is , when I touch the center of the label node , the X position of 1.) node and 2.) where I touched are consistent. But Y is not. node Y is 100, but touch Y is 266. See screenshot below:

Can someone explain why this is?
