- iOS 10.0+

This action is delivered only if the notification’s category object was configured with the
UNNotification option. To trigger this action, the user must explicitly dismiss the notification interface. For example, the user must tap the Dismiss button or swipe down on the notification interface in watchOS to trigger this action.
Ignoring a notification or flicking away a notification banner does not trigger this action.
