iOS 17: Issues with gesture recognizers interfering with custom UIView animations
I tried several approaches but none seem to work. I'm facing an issue in my iOS 17 app where a custom UIView with gesture recognizers seems to interfere with its animations. I have implemented a simple tap gesture to toggle the UIView's visibility, but the animations are not smooth, and sometimes the view does not respond at all to taps. Here’s what my setup looks like: ```swift class CustomView: UIView { private var isVisible: Bool = true private let tapGesture = UITapGestureRecognizer() override init(frame: CGRect) { super.init(frame: frame) setupGesture() } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } private func setupGesture() { tapGesture.addTarget(self, action: #selector(handleTap)) self.addGestureRecognizer(tapGesture) } @objc private func handleTap() { isVisible.toggle() animateView() } private func animateView() { UIView.animate(withDuration: 0.3) { self.alpha = self.isVisible ? 1.0 : 0.0 } } } ``` I added the gesture recognizer in the initializer, but when I tap the view, sometimes the animations don’t execute, and I get a warning in the console: `Warning: Attempt to present <UIViewController> on <UIViewController> whose view is not in the window hierarchy!`. It seems like the UIView is not in the correct state to respond to the gesture, or perhaps there are multiple gesture recognizers conflicting. I have tried the following: - Ensured that the gesture recognizer is properly added and that user interaction is enabled on the UIView. - Checked if any other gesture recognizers are affecting the tapping behavior; I have no other gesture recognizers on this view. - Used `gestureRecognizer(_:shouldRecognizeSimultaneouslyWith:)` to allow other gestures to be recognized simultaneously, but it didn't help. - Tried adjusting the view hierarchy and ensuring that the UIView is actually on-screen at the time of the tap. Are there specific configurations or best practices for handling gesture recognizers in a UIView that I might be missing? Any insight into how to ensure that the view reliably responds to taps while still performing the animations smoothly would be greatly appreciated.
