如何跟踪SwiftUI应用程序中的所有触摸

struct TouchTracker: View {
    @GestureState private var dragState = DragState.inactive
    
    var body: some View {
        Circle()
            .frame(width: 100, height: 100)
            .gesture(
                DragGesture()
                    .updating($dragState) { value, state, transaction in
                        state = .dragging(translation: value.translation)
                    }
                    .simultaneously(with: TapGesture().onEnded {
                        print("Tap gesture detected")
                    })
            )
    }
}
