Consider introspecting UIContextMenuInteraction

This would be useful because there is no way to know when the context menu appears.

Is there a method on UIContextMenuInteraction you can call to even do that? Unfortunately, if you can only detect that by overriding a method like didMove(to:), it's likely not possible.

I concur with @GeorgeElsham. There isn't much one can do because context menus don't have a publicly available UIView-based class. This is similar to how tab bar items are represented by an abstract UITabBarItem class. So even if we could pluck out the menu view casted as a UIView, it wouldn't be of much use because it lacks all relevant information.
