There seems to be a crashing issue when you have a ListView that has custom cells and a cache strategy: ListViewCachingStrategy.RecycleElement
Attached is a sample project. When you restore the packages and run it, it will show a list of two people. Then uncomment the listview strategy and see that you get a white screen and then a crash on a device that is running iOS 10 Beta 8.
A fix is becoming urgent
Having a ContextAction on a custom cell produces the same error, regardless of caching strategy.
Agreeing with the previous comment: a fix is urgent.
Can you please try upgrade to the latest stable we issue a hotfix for a very similar issue. I think it might be the same problem.
I can confirm that the hotfix works. Tested it for RecycleElement and ContextAction.
The original issue seems to be fixed but ContextAction does not work as it should.
If you swipe so that the context menu is visible on one listview item and then swipe another item (without closing the context menu on the first item), it crashes.
It raises a System.ArgumentNullException with the message:
Value cannot be null.
Parameter name: gestureRecognizer
It originates from UIKit.UIView.RemoveGestureRecognizer, from what I can tell.
This is only on iOS10. On iOS9 it works as it should.
Ok, please open a new bug relative to that subject.
