[iOS] Touches not being cancelled when Swipe Back gesture triggers

[IainS1986]

I've seen this come up in the past, and I know it originally caused issues with crashes around the Touch IDs in dictionaries and the like. The latest nuget fixes the crashes.

However I'm wondering if there's a work around to clear out all active touches maybe?

I have a full screen skia scene, and when I do the 'swipe back' gesture but cancel it, the scene appears to have the single touch during the swipe back remain 'active' in the skia scene. This then means when I touch the skia scene again with 1 touch, it acts like there are 2 touches active with one locked at the position my finger was in during the swipe back.

Do it again, and there are 2 touches remaining active. Again and its 3 and so on.

Wondering if I need to monitor te swipe back gesture, and when it completes clear skia touches?

Hope that made sense, kinda hard to describe :/

Ok, one work around.

Originally, in ViewWillAppear and ViewWillDisappear I hookedup and unhooked various touch events on a single TouchGestureRecognizer instance that was used throughout the views lifetime.

Instead, I can unhook and dispose, then recreate a new one everytime (and a new SceneGestureRenderingResponder as it has to be passed to that). That basically 'clears' the current touch state when the swipe back gesture occurs (as the swipe back calls ViewWillDisappear and ViewWillAppear on start/finish/cancel etc).

Its not elegant though so wondered if there's a nicer work around?
