Ah. I don't think this will work as described. I have a whole bunch of TextFields in a Grid. If I add a .onLongPressGesture() to the grid, I can't click on the TextFields inside the Grid.So, it is not just the gesture action dropping through the fields from front to back until it finds something, as I was thinking.

iPadOS 16.0 has 'Reference Mode'. If that came to iOS that would be most of what I am looking for.

This is a bad idea with the current gesture handling. There are many exceptions to my simple model of a gesture action dropping through the fields from front to back until it finds something that handles it. B enter question might have been 'what can replace hover when there is no mouse?'

Thanks. process launch -X false worked on my machine

process launch works for me. There is still something a bit odd as the hash was quoted in my test, which kept my zsh shell from acting as a quote, so the -X shell processing in lldb is different to the actual shell. Quote and a space works the same in both, so I will probably stick with that. But it is good to know.
