UNNotification object contains the initial notification request, which contains the notification's payload, and the date on which the notification was delivered.
Don't create notification objects directly. When handling notifications, the system delivers notification objects to your
UNUser object. The
UNUser object also maintains the list of notifications that were previously delivered, and you use the
get method to retrieve those objects.
