I'm doing something very similar but the problem is that I don't get any
mouse or touch messages at all, which is why I'm thinking it must be the
settings for my ios scroller.
Whatever the defaults are for delayTouches and canCancelTouches, I think at
least one of them needs to be changed.

I’m using this script on iOS directly inside a LC field object in order to
get a "delete button” to appear. (Ya, I know that is pretty ancient UI) But
it requires a swipe on iOS which is what you are after. I don’t think it is
responsive enough to do some of the fancy pushes that differentiate between
showing and sending things. It has been a long time since I worked on this
(and I chopped out a lot of code) so it is possible that I’ve missed
something. FYI: the field is a “List” field.
-- I use these values for swiping
put 40 into gHorizontalSwipeDistance
put 15 into gVerticalSwipeDistance

I have a tall field inside a shorter group that uses a mobile scroller. A
behavior assigned to the group handles the scrolling and checks for swipes
by capturing mouseDown and mouseUp to determine touch locations so it can
calculate the direction of the swipe. This works on Android.
On iOS I do not get mouseUp or mouseDown messages when swiping
horizontally, though I do get scrolerDidScroll when swiping vertically. But
since the group is exactly as wide as the field it encloses, it does not
scroll horizontally and so no scrollerDidScroll message is sent. I also do
not get scrollerBegin/EndDrag, touchStart or touchEnd, or any other message
I can think of to track a horizontal swipe. I do get mouseUp/Down when
tapping on the scroller but that doesn't help here.
How would I detect a horizontal swipe on a non-moving scroller? The user
can't navigate without it.
