NSPersistentCloudKitContainer

Hi! I'm using CoreData + CloudKit. It works well both on macOS and iOS, however, I can't make it work with extensions (share, action, keyboard). I get Invalid bundle ID for container error: error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _recoverFromPartialError:forStore:inMonitor:](2812): : Error recovery failed because the following fatal errors were found: { = ; } I checked everything 10x: profiles, bundle ids, entitlements, etc. I even removed all local provisioning profiles and recreated them, I also tried setting different CloudKit container, but nothing helps. I tested it on a real device. My setup: main app bundle id: com.org.App.dev keyboard bundle id: com.org.App.dev.App-Keyboard action extension bundle id: com.org.App.dev.Action-Extension CloudKit container id: iCloud.com.org.app.dev I keep the CoreData database in the app group container, but I also tried locally and it doesn't really matter. This is how I setup my CoreData: self.persistentContainer = NSPersistentCloudKitContainer

Hi, I'm currently developing a SwiftUI based app with Core Data and CloudKit sync with the NSPersistentCloudKitContainer. I found different solutions how to toggle CloudKit sync of the Core Data during runtime. The basic idea of these solutions is the following. instantiate a new NSPersistentCloudKitContainer set storeDescription.cloudKitContainerOptions = nil load persistence store Some solutions recommend to restart the app manually to avoid exactly my problem. Issues So far so good. How can I distribute the new viewContext through my app during runtime. In the main App I distributed the viewContext during startup via @Environment(.managedObjectContext) and it seems not be updated automatically after a reinitialization of NSPersistentCloudKitContainer. var body: some Scene { WindowGroup { ContentView() .environment(.managedObjectContext, persistence.container.viewContext) } } After deactivating the CloudKit sync I receive the following error when I try to add a new entity. [error]

Hi, I want to activate/deactivate the CloudKit Sync during App runtime in a user settings view. Basically this works fine. Every time I toggle between the NSPersistentContainer and the NSPersistentCloudKitContainer, I increase the persistence.persistenceContainerReloaded attribute and the whole view hierarchy will be reloaded. Thus all changes are passed through the whole app. During the reload phase I have to load a new persistence store by container.loadPersistentStores(...). Unfortunately, I cannot remove the old persistence store before loading the new one. The app crashes immediately, because the store and viewContext is still in use. Therefore, I just create a new one and trigger the reload. Afterwards every view is using the new viewContext. But somewhere in the background there is still the old persistence store with CloudKit Sync active and pushes every local change to the cloud. Changes on the cloud from other devices are not received anymore. Does someone has any idea, how to correctly unl

My iOS app uses Core Data for local data management and NSPersistentCloudKitContainer to sync data with user’s private iCloud storage. The app has been functioning correctly for several years, but recently, some users have started encountering a CKError.partialFailure error when the app attempts to export data to iCloud. Due to the critical nature of export errors, several features in the app have been disabled to prevent potential data duplication. Core Data Setup: lazy var container: NSPersistentContainer = { let container: NSPersistentContainer if storeType == .inMemory { // Used by unit tests container = NSPersistentContainer(name: models) container.persistentStoreDescriptions.first!.url = URL(fileURLWithPath: /dev/null) } else { container = NSPersistentCloudKitContainer(name: models) } container.loadPersistentStores { [weak self] _, error in if let error = error { self?.logger.error(Failed to load persistent store: (error)) fatalError() } } return container }() lazy var context: NSManag

My app uses SwiftData and CloudKit to store and synchronize data. This works nice. in some scenarios, I need to listen to NSPersistentStoreRemoteChange event to deduplicate data. In SwiftData, how do I get the persistentStoreCoordinator of the corresponding SwiftData ModelContainer? Or are there other APIs to achieve the same purpose? There is no relevant content in the developer documentation. In addition, in wwdc 24, there is a new API to track history (https://developer.apple.com/cn/videos/play/wwdc2024/10075/). But there is no mention of how to listen to remote data change events either.

On top of unstable CloudKit sync, we've got also extremely unstable sharing/collaboration functionality. I mean, it's quite impressive how easy it is to enable sharing, but this feature should not be released at this point. It feels like using software in the alpha version. Let's take NSPersistentCloudKitContainer.share(_:to:) (https://developer.apple.com/documentation/coredata/nspersistentcloudkitcontainer/3746834-share), the documentation says: Sharing fails if any of the following conditions apply: Any objects in managedObjects, or those the traversal finds, belong to > an existing share record. However, it's wrong... if you pass any object from the existing share, it will return the same share... It never fails in this case. Things are getting even weirder if you experiment a little bit with shares. So let's assume you share a couple of objects: persistentContainer.share([A, B, C, D], to: nil) Now you stop sharing those via UICloudSharingController and you want to share again but just C. So yo

Hello everyone, I'm currently working on an iOS app using SwiftUI and Core Data, integrating CloudKit for data synchronization. I've set up my Core Data stack with NSPersistentCloudKitContainer, and everything appears to be working correctly locally. However, I'm not seeing any records appearing in the CloudKit Dashboard. This issue started occurring after transferring the Apple Developer account ownership and changing the CloudKit container. Here's a summary of my setup and what I've tried so far: Setup PersistenceController.swift import SwiftUI import Foundation import CoreData import CloudKit class PersistenceController { static let shared = PersistenceController() let container: NSPersistentCloudKitContainer init() { container = NSPersistentCloudKitContainer(name: Model) guard let description = container.persistentStoreDescriptions.first else { fatalError(No Descriptions found) } description.cloudKitContainerOptions = NSPersistentCloudKitContainerOptions(containerIdentifier: iCl
