Can there be multiple SKNodes in a UITapGestureRecognizer

When I'm dealing with touchesBegan, moved, etc. I am able to loop through every item at the CGPoint where the action occurred. So obviously I am dealing with everything through my GameScene.

Now when working with UITapGestureRecognizer, I can't seem to come up with the code that would tell me if there are multiple items at the point of tapping (single tap only). It's not that I want that to happen, but I fear my code may crash if it does occur.

Should UITapGestureRecognizer be handled by each SKNode that uses it? Or is there a code solution where I can handle it all through GameScene?

Here is how I deal with touches_:

Code Block 
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?){
        guard let touch = touches.first else { return }
        let location = touch.location(in: self)
        let touchedNodes = self.nodes(at: location)
        for theNode in  touchedNodes{
            if let node = theNode as? MyBall {
			.......my code,......
                }
            }
        }
      }

And here's how I handle UITapGestureRecognizer, yet unable to figure out code to see if there's more than one SKNode:

Code Block 
@objc func tappedView(_ sender:UITapGestureRecognizer) {
    if sender.state == .ended{
        let point : CGPoint = sender.location(in: self.view)
		var post = sender.location(in: sender.view)
        post = self.convertPoint(fromView: post)
        if let touchNode = self.atPoint(post) as? Ball{
		......my code.......
        }
    }
}

Code Block 
for touchNode in self.nodes(at:post){
... }
