Apple platform
iOS
Framework version

Affected platform version
.Net 9.102
Description
If you use the binding for WillRepositionPopover at all it will cause a crash on simulators (iPhone and iPad). I have attempted to simply call base in the method and that will cause the crash as well. Physical devices seem to be unaffected by this issue.
Steps to Reproduce
- Create a tableview that presents a popover view when cells are tapped.
- Have the view implement IUIPopoverPresentationControllerDelegate
- Override the WillRepositionPopover function
- Run the app and attempt to present the popover
Did you find any workaround?
Run on a physical device to avoid crashing.
