Handling Push Notifications when App is Terminated

Question

When my App is not running and receives a Push Notification, if I click on that notification, the App is launched - but then it doesn\'t prompt the user with the Alert-View

Answer 1

You can retrieve notifications delivered to your app by using the getDeliveredNotifications(completionHandler:) method. Note that this only returns notifications currently displayed in the Notification Center and not the ones that have been manually cleared by the user.

UNUserNotificationCenter.current().getDeliveredNotifications { notifications in

    // notifications: An array of UNNotification objects representing the local
    // and remote notifications of your app that have been delivered and are still
    // visible in Notification Center. If none of your app’s notifications are
    // visible in Notification Center, the array is empty.

    // As said in the documentation, this closure may be executed in a background
    // thread, so if you want to update your UI you'll need to do the following:
    DispatchQueue.main.sync { /* or .async {} */ 
        // update UI
    }
}
