@colint ok, I'll stop with this last code, surely not perfect but, I think, sufficient to show you that you can do it like you asked. Even long swipe (where delete button width is more than half screen) is foreseen and simulates the tap of the delete button. Try the code and give me some feed-back.
I'm sure that you could ameliorate it in a better way than mine,
