What's UserNotification framework's equivalent of didReceive notification: UILocalNotification?

Question

I already knew about this code which can be used before iOS 10:

func application(_ application: UIApplication, didReceive notification: UILocalNotification) {

}

However, it's depreciated so I just want to ask is there any method that is equivalent to the UserNotifications framework or I just have to get by with this warning?

Note that I want the app to do something when app is in the background or is terminated.

Answer 1

The deprecated method was notifying delegate when the app received notification while in foreground. Now UNUserNotificationCenterDelegate does the same thing:

func userNotificationCenter(
    UNUserNotificationCenter, 
    willPresent: UNNotification, 
    withCompletionHandler: @escaping (UNNotificationPresentationOptions) -> Void
)

Called when a notification is delivered to a foreground app.
