Setting UIView to Start From Upper-Left Corner (0,0)

Question

I adapted a UIPanGestureRecognizer to use pull-down to dismiss view. I made it like this, so now the view can be dragged the in y-axis and if change in y is greater than 100, it dismisses the view.

override func viewDidLoad() {
    super.viewDidLoad()

    let myPanGestureRecognizer = UIPanGestureRecognizer(target: self, action: "myPanAction:")
    self.player.view.addGestureRecognizer(myPanGestureRecognizer)
}

func myPanAction(recognizer: UIPanGestureRecognizer) {
    let translation = recognizer.translationInView(self.view)
        if let myView = recognizer.view {
            myView.center = CGPoint(x: myView.center.x, y: myView.center.y + translation.y)
        }
        recognizer.setTranslation(CGPointZero, inView: self.view)

        if recognizer.state == UIGestureRecognizerState.Ended {
            let velocity = recognizer.velocityInView(self.view)

            if velocity.y > 100 {
                dismissViewControllerAnimated(true, completion: nil)
            } else {
                // Reposition Back                   
            }
        }
}

However, I want to position the view back to its original place but, I couldn't figure out how..

Also, is my approach a good way of doing it or is it a very primitive approach?

Can you please try to add on the // Reposition Back comment the following code:

let frame = myView.frame // Get the current view frame
frame.origin = CGPointZero // Change the frame origin to x:0 y:0
myView.frame = frame // Change the myView frame to frame
