How to dismiss popover View controller on iPad on tapping outside the view : IOS 9

i m trying to present a view controller as popoverviewcontroller using modal style of type .pagesheet. Here i m trying to add a tap gesture recognizer to dismiss this popoverviewcontroller on clicking ouside its view. But it is not detecting tap in iOS 9. Here is the code below of gesture recognizer 

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
        let recog : UITapGestureRecognizer = UITapGestureRecognizer.init(target: self, action:#selector(HandleTap))
        recog.numberOfTapsRequired = 1
        recog.numberOfTouchesRequired = 1
        recog.cancelsTouchesInView = false
        recog.delegate = self
        self.view.window?.addGestureRecognizer(recog)

    }


func HandleTap(sender:UITapGestureRecognizer) -> Void
{
    if(sender.state == UIGestureRecognizerState.Ended)
    {
        var location : CGPoint = sender.locationInView(self.presentingViewController?.view)
        //var location : CGPoint = sender.locationInView(self.view?.window)
        if(!(self.view.pointInside(self.view.convertPoint(location, toView: self.view?.window), withEvent: nil)))
        {
          self.view.window?.removeGestureRecognizer(sender)
          self.dismissViewControllerAnimated(true, completion: nil)
        }
    }
}

Set userinteractionenable to true on view on which you handle the tap. and second thing why you are doing your stuff in viewDidAppear? You should use viewDidLoad to add gesture recognizer.

Update :

self.view.window?.userInteractionEnabled = true

if you are using navigation controller then 

self.navigationController?.view.window?.userInteractionEnabled = true

hope thiw will help :)
