why is bringSubviewToFront() only working for panning, not tapping? - swift

Question

view.bringSubviewToFront(tappedView)
is working when I drag (pan) views but not when I tap them. My issue is that when I have one view layered over the other, I want the bottom view to come to the front when tapped. Currently it will only come to the front when dragged. Do I need some additional code to do this? Thanks.
Here's an excerpt from my code for more context:
#objc func didPan(_ recognizer: UIPanGestureRecognizer) {
let location = recognizer.location(in: self.view)
switch recognizer.state {
case .began:
currentTappedView = moviePieceView.filter { pieceView -> Bool in
let convertedLocation = view.convert(location, to: pieceView)
return pieceView.point(inside: convertedLocation, with: nil)
}.first
currentTargetView = movieTargetView.filter { $0.pieceView == currentTappedView }.first
case .changed:
guard let tappedView = currentTappedView else { return }
let translation = recognizer.translation(in: self.view)
tappedView.center = CGPoint(x: tappedView.center.x + translation.x, y: tappedView.center.y + translation.y)
recognizer.setTranslation(.zero, in: view)
view.bringSubviewToFront(tappedView)
```

Answer 1

I had this same problem, I managed to solve it this way:
Add a gestureRecognizer to your view and put this in your code. Don't forget to set the delegate as well when attaching this to the code!
#IBAction func tappedView1(recognizer: UITapGestureRecognizer) {
view.bringSubviewToFront(myView)
}
Put this in your viewDidLoad:
let tap = UITapGestureRecognizer(target: self, action: #selector(tappedView1))
tap.cancelsTouchesInView = false
self.view.addGestureRecognizer(tap)
If you want to do that from your panGesture check my question.

Thank you all. It worked when I wrote a second function in addition to didPan().
This is the additional code:
override func viewDidLoad() {
super.viewDidLoad()
configureLabel()
let panGestureRecognizer = UIPanGestureRecognizer(target: self, action: #selector(didPan(_:)))
view.addGestureRecognizer(panGestureRecognizer)
let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(didTap(_:)))
view.addGestureRecognizer(tapGestureRecognizer)
}
#objc func didTap(_ recognizer: UITapGestureRecognizer) {
let location = recognizer.location(in: self.view)
currentTappedView = moviePieceView.filter { pieceView -> Bool in
let convertedLocation = view.convert(location, to: pieceView)
return pieceView.point(inside: convertedLocation, with: nil)
}.first
guard let tappedView = currentTappedView else { return }
view.bringSubviewToFront(tappedView)
}
HOWEVER, I found out you can also just tick the "User Interaction Enabled" box in the Image View if you don't want to do it programmatically.
