I had push notifications from CloudKit working and I'm afraid I've done something to break them. If anyone can see something I don't, please help.

When the app launches, I call setupSubscriptions(), which has this code:

let predicate = NSPredicate(value: true)
let subscriptionID = "public-new-changes-deleted"
let subscription = CKQuerySubscription(recordType: recordType, predicate: predicate, subscriptionID: subscriptionID, options: [.firesOnRecordCreation, .firesOnRecordUpdate, .firesOnRecordDeletion])
let notificationInfo = CKSubscription.NotificationInfo()
notificationInfo.shouldSendContentAvailable = true
subscription.notificationInfo = notificationInfo

publicDB.save(subscription) { subscription, error in
if error != nil 
 print("subscription was set up")

The setup message does fire. I've also tried making the notificationInfo CKQuerySubscription.NotificationInfo, but there's no discernible difference whether it's that or CKSubscription.

In my app delegate:

application.registerForRemoteNotifications()

I do get a message from application(_ application:, didRegisterForRemoteNotificationsWithDeviceToken:) that the application has registered for notifications.

Then I have:

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) 
 print("application did receive remote notification")

Next I got to my CloudKit Dashboard and create, modify, or delete a record but nothing happens. I'd expect a message from didReceiveRemoteNotification. but nothing. This was working earlier but I can't think of what I changed to break it.

I can create records there and query for them in the app, so I'm sure it's able to see them, but I can't get a push when they're altered.

Other stuff:

In my target's Capabilities tab:

• Background Fetch and Remote Notifications are both checked under Background Modes.


• iCloud is on and it's using the correct container -- I can do fetches just fine from CloudKit using the same recordType and publicDB CKDatabase object.


• Push Notifications are turned on and my entitlements file has a flag for "APS Environment" with a value of development.

On my Apple Developer account page, under the App ID, iCloud and Push Notifications both have green lights for both "Development" and "Distribution."

I can see in the CloudKit dashboard that the subscription types are created once the app's been run.

I'm testing on a device, not in the simulator.

I've tried:

• Changing whether I create the subscription before or after I register for notifications.


• Adding a message body, alert sound, and shouldBadge, and requesting notifications using UNUserNotificationCenter, and making the App Delegate a UNUserNotificationCenterDelegate. I get the prompt when I first run the app but the notifications don't arrive.


• Splitting the subscriptions up into one for .firesOnRecordCreation and one for update and delete.


• Adding the subscriptions using a CKModifySubscriptionsOperation instead of the database's save method.

Please let me know if you have any ideas. Thank you.
