iOS 10 How to view a list of pending notifications using UNUserNotificationCenter?

Question

Solution Code:

let center = UNUserNotificationCenter.current()
print(center.getPendingNotificationRequests(completionHandler: { error in
        // error handling here
    }))

My original post:

I am trying to get a list of pending notifications via UNUserNotificationCenter as UIApplication.shared.scheduledLocalNotifications was depreciated.

This is the code I'm using:

let center = UNUserNotificationCenter.current()
    print(UNUserNotificationCenter.getPendingNotificationRequests(center))

However this prints "(Function)". getPendingNotificationRequests requires a UNUserNotificationCenter parameter and I can't think of what else it could be.

Thanks

Call that function on `center`, not on the class and provide a callback handler https://developer.apple.com/reference/usernotifications/unusernotificationcenter/1649513-getpendingnotificationrequests — Paulw11, Oct 26 '16 at 19:32
First make sure you've authorization, then you can schedule notification. — Idan Moshe, Oct 05 '20 at 10:41

The getPendingNotificationRequests call passes an array of requests to the completion closure. Try something like this:

let center = UNUserNotificationCenter.current()
center.getPendingNotificationRequests(completionHandler: { requests in
    for request in requests {
        print(request)
    }
})

@Abhishek Are you sure they are being scheduled correctly? Do the notifications show properly? – Ian Kohlert Jan 25 '20 at 14:54

Notifications are getting scheduled properly. But getting requests count as 0. – Abhishek Jan 27 '20 at 06:32

@Abhishek I'm having the same issue. Have you figured it out already? – lajosdeme Jun 26 '20 at 14:45
How do you print the title? it just shows redacted for all of them – Curtis Jan 16 '21 at 06:13
Make sure your app has requested the authorization to send notifications and you have accepted. That might be the reason for some of you to see 0. – Kqtr Jan 18 '21 at 16:09

Just in case anyone needs to access notifications that are already delivered (user can see them in notification center), this can be done in the following way:

    let center = UNUserNotificationCenter.current()
    center.getDeliveredNotifications { notifications in
            // use center.removeDeliveredNotifications(withIdentifiers:requestIdsToRemove)
            // if you want to cancel some of the notifications displayed to user
        }
    }

it's not actually now, but you should allow to use notifications

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
        if !granted {
            print("user has declined notifications")
        }
    }

For ObjC:- [[UNUserNotificationCenter currentNotificationCenter] getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest*> *requests){ NSLog(@"requests: %@", requests); }];
