ios - 单按不能与双按组合使用

Question

为了进行图像显示，我附加了几个手势，除单击外，所有手势均按预期工作。
下面是图像以及附加的手势:

Image(uiImage: UIImage(named: "shatan_tree.png")!)
                .gesture(TapGesture(count: 2)
                            .onEnded({
                                // this code is executed as expected
                            }).simultaneously(with: DragGesture(minimumDistance: 0, coordinateSpace: .global).onChanged({ 
                               // this code is executed as expected
                            })
                            .onEnded({ (value) in
                                // this code is executed as expected
                            })))
                .gesture(TapGesture(count: 1)
                            .onEnded({
                                // this doesn't work
                                print("single tap")
                            }))
                .gesture(MagnificationGesture()
                            .onChanged({ (scale) in
                                // this code is executed as expected
                            })
                            .onEnded({ (scaleFinal) in
                                // this code is executed as expected
                            }))

有谁知道这可能是什么问题，以及如何与其他手势一起启用单击手势？
谢谢。

它由DragGesture(minimumDistance: 0...消耗，因此解决方案要么使拖动真正至少拖动一些DragGesture(minimumDistance: 1...或同时单击.simultaneousGesture(TapGesture(count: 1)
