ViewOnTouch
Detect event and coordinates of touch on SwiftUI view Inspired by https://www.hackingwithswift.com/quick-start/swiftui/how-to-detect-the-location-of-a-tap-inside-a-view
- supported events:
- started
- moved
- ended
- tapGesture
- longGestureStarted
- longGestureMoved
- longGestureEnded
Notes: Be careful when you handle touches of view located on scroll view. Simple tap on view in this case triggers tapGesture event only.

MyView()
.onTouch(type: longGestureAction == nil ? .allWithoutLongGesture : .all,
perform: { location, event in
print("\(location) - \(event.rawValue)")
if event == .started {
viewModel.isTouchHandling = true
viewModel.touchDown?(location)
} else if event == .moved {
viewModel.touchMove?(location)
} else if event == .ended {
viewModel.isTouchHandling = false
viewModel.touchUp?(location)
} else if event == .tapGesture && !viewModel.isTouchHandling {
viewModel.touchDown?(location)
viewModel.touchUp?(location)
tapAction?()
} else if event == .longGestureStarted {
longGestureAction?(location, .started)
} else if event == .longGestureMoved {
longGestureAction?(location, .moved)
} else if event == .longGestureEnded {
longGestureAction?(location, .ended)
}
