“NSPersistentCloudKitContainer”

I've set up a Core Data mirroring to CloudKit using NSPersistentCloudKitContainer. My simplified data structure consists of List and Item. List have one-to-many relationship items with many Items, Item has parentList property. When I am getting CKRecord associated with List NSManagedObject and sharing it, I expect all child Items to be shared too. I know, I can set parentRecord property for each CKRecord associated with the List childRecord.setParent(parentRecord) But I believe there is some smart way to avoid doing that manually, because everything is mirroring automatically and it looks not nice to start handling each single property manually to only set parentRecord. Is there any way to do that for NSManagedObjects? Because my custom relationship does not mean for CloudKit that the List is parent for the Item.

Hi, I am developing sharing feature with already working mirroring and need to set parentRecord to child items. I want to extend NSPersistentCloudKitContainer (or any it's component used for mirroring) in some way to get access to CKRecords it is creating before container will push records to the server. Goal — I want to set CKRecord.parent right before CKModifyRecordsOperation fires somewhere in NSPersistentCloudKitContainer. Reason — NSPersistentCloudKitContainer do not handle parent records by itself.

Hi everyone, I am very new to SwiftUi and am not sure about data collection to disclose. Does using the sign in with Apple feature and Core Data with CloudKit count as Data Collection? (if it does what would it come under) I use @AppStorage for the sign in and not the UserDeafult feature. For CloudKit I only use the inbuilt NSPersistentCloudKitContainer container and for saving the generic: viewContext.automaticallyMergesChangesFromParent = true viewContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy Thank you

Hello everyone, in the App I'm building I'd like to share an entire list of items (records) by just sharing the list itself (parent record or RecordZone). Meanwhile, I'd like to continue using the NSPersistentCloudKitContainer and therefore CoreData sync. Is it possible, with the new features Apple introduced (Sharing RecordZone and Sharing in Cloud & Local Storage), to do what I described, and combine both functions. Thank you, Carlos Steiner

Hello. I'm trying to setup CoreData+CloudKit integration. But I receive following errors right after NSPersistentCloudKitContainer configuration.

Hopefully everyone's recovered from WWDC2021 last week! I've been digging through as much of the new documentation as I can about the NSPersistentCloudKitContainer and sharing over the last couple of days (since I can't get my code working in the XC 13 Beta... looks like a couple of bugs, I think...), and have a question. It appears that this uses Sharing by Record Zone rather than Sharing by Record, which is fine, but... How does this work when you are sharing entities between multiple users? for example... My Db contains a hierarchy of entities under a single root node, and there are multiple such entities (at the moment without overlap between the sub-entities, but I feel like that's just around the corner). Lets call them Entities A, B, and C. Now: Entity A I want to share with Joe. Entity B I want to share with Joe and Sally. Entity C I want to share with Sally and Simon. So, for Entity A I presume that it (and it's sub entities) wind up being represented in a shared record zone (SRZ) of it's ow

Can the behavior of NSPersistentCloudKitContainer be described in App Extensions? I have seen Forum entries that describe its behavior in Widgets - it will save data locally, but will not sync that data until the app is opened. This is a pretty major downsides for any apps that use SiriKit Extensions to allow for quick, simple data entry -- not syncing the data until the app is opened (which could be days later) would be a deal breaker. I hope this can be clearly described, and improved (if my understanding is correct) - I've filed a feedback to document this as well: FB9170155

Hello Is there a way to share data stored in CloudKit and CoreData between iOS and watchOS in SwiftUI? I am using the same CoreData file both, and I am using the same PersistenceController file both, and I am using the same CloudKit container for both. I tried adding the App Groups capability to all the targets, but it is not working. (I already enabled iCloud capability, Push notification capability and background Modes capability for both iOS and WatchOS) PersistenceController: struct PersistenceController { static let shared = PersistenceController() static var preview: PersistenceController = { let result = PersistenceController(inMemory: true) let viewContext = result.container.viewContext do { try viewContext.save() } catch { let nsError = error as NSError fatalError(Unresolved error (nsError), (nsError.userInfo)) } return result }() let container: NSPersistentCloudKitContainer init(inMemory: Bool = false) { container = NSPersistentCloudKitContainer(name: Test7) if inMemory { container

Hi I have an app that runs on iOS and MacOS (actually they are separate apps) and Core Data from a NSPersistentContainer, is synced with iCloud using a custom solution utilising pre-NSPersistentCloudKitContainer CloudKit methods. I would like to migrate that solution to NSPersistentCloudKitContainer but am having trouble figuring out how to do it and whether it's even possible. In particular, as I cannot guarantee that all devices would migrate at the same time, there would need to be a period where both synchronisation methods are active. Moreover, they would need to be active on one device, which would need to act as some sort of translator between the two methods. Then, it would be quite hard to determine when to stop using and delete old records from the cloud as that would have to be done from the last device to migrate. And that would be quite hard to determine from the app. Finally, as each device has its own Core Data objectIDs all managed objects would end up being duplicated in iCl

I'm struggling to initialize my schema. I keep getting the error : Error Domain=NSCocoaErrorDomain Code=134060 A Core Data error occurred. UserInfo={NSLocalizedFailureReason=Couldn't initialize CloudKit schema because no stores in the coordinator are configured to use CloudKit Without the initialize it does sometimes create the record's schema. But it feels like its all half working. I have Cloudkit on and Used with Cloudkit is checked under the default configuration in my xcdatamodeld file. Here is my setup code.. _persistentContainer = [[NSPersistentCloudKitContainer alloc] initWithName:@Eco-nomy]; // Add options and make this container PUBLIC. NSPersistentStoreDescription *description = _persistentContainer.persistentStoreDescriptions.firstObject; [description setOption:[NSNumber numberWithBool:YES] forKey:NSPersistentHistoryTrackingKey]; [description setOption:[NSNumber numberWithBool:YES] forKey:NSPersistentStoreRemoteChangeNotificationPostOptionKey]; description.cloudKitContainerOptions.databas

I have a simple shopping list app that is using Core Data with Cloudkit. A user creates a list then adds items to the list. The list can be shared to other users. Core Data is first used to save the Lists and Items as NSManaged Objects. A list is then shared to another user who can add to items to the list, and both users working on the same list stay in sync with each other. This is all mostly working but I am having some trouble getting Core Data to update the locally stored NSManaged objects with changes from the Cloud Kit Share. Currently the app is dealing with a mix of NSManaged Objects and CKRecords to display in the table View that shows the items on a list. Which is a bit messy. I really want to just work with NSManaged Objects with Cloudkit doing the work of keeping things in sync between the 2 users. When User B adds an Item it successfully saves to the Shared Database and sets the parent as the list that was shared. This is where I get a bit stuck as I want User A to see the Item that User B added

Situation I'm working on an app in which the user can manually enter in data. That data gets locally stored in a CoreData database and from there automatically synced (via NSPersistentCloudKitContainer) to the user private CloudKit database and I selected CloudKit encryption for every attribute. So as the developer I definitely can't access it, but it's stored on some remote server.

Is it possible to manually fetch updates over NSPersistentCloudKitContainer? e.g. to allow users request newest data by themselves by pull refresh / some other mechanism?
