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.
