My solution is a bit hacky. I added the built-in tool PKToolPicker and displayed the tools. When selecting Text("Lasso"), I set self.toolPicker.setVisible(true, forFirstResponder: context.coordinator) so that PKLassoTool can be used. When selecting other tools, I set self.toolPicker.setVisible(false, forFirstResponder: context.coordinator). It's quite cumbersome, and I hope there is a better way. let toolPicker = PKToolPicker() func makeCoordinator() -> Coordinator { Coordinator() } class Coordinator: NSObject, PKToolPickerObserver { .... }

Why doesn't Apple pay attention to this bug? A year has passed since then.

Why doesn't Apple pay attention to this bug?

I had the same problem, and what's worse, when I changed all the buttons to “Button action” form, the “override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) ” in my UIVIEW. doesn't work. I tried to add a piece of code “ .gesture(DragGesture() .onChanged { value in } .onEnded { value in } ) ” and it gets better, but sometimes it still fails to click! #if targetEnvironment(macCatalyst) Anytools() .gesture(DragGesture() .onChanged { value in } .onEnded { value in } ) #else Anytools() #endif
