SwiftUI UIKit GestureRecognizer Swift

I tried several approaches but none seem to work... I'm trying to figure out I'm having trouble with I'm experiencing an inconsistency with gesture recognizers when integrating a UIKit view into my SwiftUI app... I'm using an `UIViewControllerRepresentable` to display a custom camera view in my SwiftUI app, specifically on an iPhone 12. The issue arises when I try to add pinch and swipe gestures to the camera view. Sometimes, the gestures don't register at all, and other times they conflict with the default swipe-to-dismiss behavior of SwiftUI views. Here's the code snippet where I set up the gestures: ```swift struct CameraView: UIViewControllerRepresentable { class Coordinator: NSObject, UIGestureRecognizerDelegate { var parent: CameraView init(parent: CameraView) { self.parent = parent } @objc func handlePinch(_ gesture: UIPinchGestureRecognizer) { // Handle pinch here } @objc func handleSwipe(_ gesture: UISwipeGestureRecognizer) { // Handle swipe here } } func makeCoordinator() -> Coordinator { Coordinator(parent: self) } func makeUIViewController(context: Context) -> UIViewController { let viewController = UIViewController() let pinchGesture = UIPinchGestureRecognizer(target: context.coordinator, action: #selector(Coordinator.handlePinch(_:))) pinchGesture.delegate = context.coordinator viewController.view.addGestureRecognizer(pinchGesture) let swipeGesture = UISwipeGestureRecognizer(target: context.coordinator, action: #selector(Coordinator.handleSwipe(_:))) swipeGesture.delegate = context.coordinator viewController.view.addGestureRecognizer(swipeGesture) return viewController } func updateUIViewController(_ uiViewController: UIViewController, context: Context) { // Update logic here } } ``` I have also set the `delegate` of the gesture recognizers, but still, the pinch sometimes does not get recognized when swiping is supposed to occur. I tried implementing the `gestureRecognizer(_:shouldRecognizeSimultaneouslyWith:)` delegate method to allow simultaneous recognition, but that only leads to the pinch gesture being ignored. ```swift func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool { return true // Allow simultaneous gesture recognition } ``` But this doesn't seem to resolve the issue properly. The default behavior of the swipe gesture causes the pinch to not function as expected. I've tested it on both the simulator and an actual device, and the behavior is inconsistent. What could be causing this, and how can I ensure the gestures work reliably together? I've been using Swift for about a year now. What would be the recommended way to handle this?
