Awesome! This works great and is so much simpler. I'll update the article.

The only problem is observing when the GestureState changes. In iOS 14, I can use .onChange(of:perform:). But in iOS 13, that's not supported.

I also tried using a custom Binding, but GestureState's set is read-only.

Did you get this working? Thanks for all your help anyway!
