Hi,

My macOS app's production build is crashing on start with an unhelpful crashdump. In the console, the only error in the Console is

BUG IN CLIENT OF CLOUDKIT: Not entitled to listen to push notifications. Please add the &#039;com.apple.private.aps-connection-initiate&#039; entitlement.

Adding this entitlement to my entitlements.plist breaks the app entirely (Unsatisfied entitlements). Here is how I'm loading my persisten store:

     lazy var persistentContainer: NSPersistentCloudKitContainer = {
        let container = NSPersistentCloudKitContainer(name: "ChatModel")
        guard let description = container.persistentStoreDescriptions.first else {
            fatalError("###\(#function): Failed to retrieve a persistent store description.")
        }
        if(UserDefaults.standard.bool(forKey: StoredPreferenceKey.iCloudSync)){
            description.cloudKitContainerOptions = NSPersistentCloudKitContainerOptions(containerIdentifier: "iCloud.XXXXX")
        } else {
            description.cloudKitContainerOptions = nil
        }
        description.setOption(true as NSNumber, forKey: NSPersistentHistoryTrackingKey)
        description.setOption(true as NSNumber, forKey: NSPersistentStoreRemoteChangeNotificationPostOptionKey)
&#x2F;* #if DEBUG
        do {
            &#x2F;&#x2F; Use the container to initialize the development schema.
            try container.initializeCloudKitSchema(options: [])
        } catch {
            &#x2F;&#x2F; Handle any errors.
        }
#endif *&#x2F;
        container.loadPersistentStores { description, error in
            if let error = error {
                fatalError("Unable to load persistent stores: \(error)")
            }
        }
        container.viewContext.automaticallyMergesChangesFromParent = true
        
        return container
    }()

I've set up Core Data + CloudKit following the official docs, screenshots attached.

The app works fine in development mode. I'm using Xcode 14.3, and I've tried with Xcode 14.2 too.

Any idea ? Web results (i.e. only two relevant threads) bring no answer.

Is this a standard app? Or something else?

Would you be able to install the CloudKit logging profile, reproduce the issue, take a sysdiagnose, and submit a bug through Feedback Assistant on CloudKit?

Yes, the same thing happened to me today. I forgot to add the "Capabilities" to each of my targets. I think you need to enable the "Background Modes" one, with 'Remote Notifications' and 'Background Fetch' checked in addition to just iCloud.
