This is also a good option if you just want to obtain the touch position.
.allTouchGestureModifier是一个SwiftUI的Modifier。有了它，你就可以使用UIKit中最重要的几个点按手势。不仅如此，你还可以访问点按位置！ 哪怕只是为了获取点按位置，.allTouchGestureModifier也值得尝试！
| Supported Gesture |
|---|
| touchDown |
| confirm(touchUpInside) |
| touchUp |
| cancel(touchUpOutside) |
| dragging |
| dragInside |
| dragOutside |
| dragEnter |
| dragExit |

Simply copy the file Sources/AllTouchGestureModifier.swift to your project.
或者直接复制Sources/AllTouchGestureModifier.swift到你的项目。
On any View you want to detect the gestures, simply add the modifier and provide the closure you want to use.
在任何需要检测手势的View上使用Modifier并提供对应的闭包就可以了。
Note that you need to import AllTouchGestureModifier first.
记得加上import AllTouchGestureModifier .
struct AllTouchGesturePreview: View {
@State private var pos: CGPoint = .zero
@State private var states: [TouchState] = [.touchUp,.touchUp,.touchUp,.touchUp,.touchUp,.touchUp,.touchUp,.touchUp,.touchUp,.touchUp]

self.states.append(.touchDown)
