NSPersistentCloudKitContainer

I have Core Data setup with a NSPersistentCloudKitContainer as my container, I've added a container identifier and I see my data on CloudKit's database here when I use Act As iCloud Account. Here's what I have under capabilities in Xcode However, on my device when I go to Settings > Apple Account > iCloud > Saved to iCloud and switch off my app, all the data saved to Core Data is removed. I suspected this working as intended. When I switch it back on, all the data comes back. However (x2), the support page here says it should remain on the device: When you turn it off, the app no longer connects with iCloud, so your data exists only on your device Am I missing something in how I integrated Core Data in Xcode? Do I need to explicitly configure something with Apple's SDK to get the behavior described in the support page? I've noticed for some of Apple's apps, when you switch off iCloud there's an action sheet asking what you'd like to do with the local data. I figured this was Apple's magic wi

I'm facing a weird issue with SwiftData. I want to have one database that's local to the device and one that syncs to iCloud. In this example, LTRLink should be synced via iCloud while LTRMetadata should stay on-device only. I've it configured like the following: let schema = Schema([LTRLink.self, LTRMetadata.self]) let cloudkitConfiguration = ModelConfiguration(Remote, schema: schema, url: FileManager.remoteDatabaseFolderURL.appending(path: Remote.sqlite), cloudKitDatabase: .private(iCloud.com.xavimoll.abyss3)) let localConfiguration = ModelConfiguration(Local, schema: schema, url: FileManager.localDatabaseFolderURL.appending(path: Local.sqlite), cloudKitDatabase: .none) return try ModelContainer(for: schema, configurations: [cloudkitConfiguration, localConfiguration]) For some reason, when I create the iCloud schema, both models end up appearing as records on iCloud. I create the schema like this: let schema = Schema([LTRLink.self, LTRMetadata.self]) let cloudkitConfiguration = ModelConfiguration(Remote, sc

I'm a bit lost because of a problem I never experienced before: I create entries in 3 Core Data tables and link them. As long as the app is open, everything is fine, I can see the database entries in the three tables. Once the App is closed and restarted, however, the new entries in two of the three tables are gone. I use Core Data for data storage and DB Browser for SQLite for inspecting the database running in the Simulator. Here's the relevant function where all Core Data handling happens: /** Creates a new ComposedFoodItem from the ComposedFoodItemViewModel. Creates the related FoodItem and the Ingredients. Creates all relationships. - Parameter composedFoodItemVM: The source view model. - Returns: A Core Data ComposedFoodItem; nil if there are no Ingredients. */ static func create(from composedFoodItemVM: ComposedFoodItemViewModel, generateTypicalAmounts: Bool) -> ComposedFoodItem? { debugPrint(AppDelegate.persistentContainer.persistentStoreDescriptions) // The location of the .sqlite file let moc = A

I'm using NSPersistentCloudKitContainer to sync CoreData to CloudKit public database but I have the problem that canUpdateRecord always returns true even for objects created by another iCloud user with _icloud role permission set to Read only. Am I missing something?

Hello all! I'm porting a ios15+ swiftui app to be compatible with Swift 6 and enabling strict concurrency checking gave me a warning that will be an error when switching to swift 6. I'm initializing a persistence controller for my cloud kit container: import CoreData struct PersistenceController { static let shared = PersistenceController() let container: NSPersistentCloudKitContainer init() { container = NSPersistentCloudKitContainer(name: IBreviary) container.loadPersistentStores(completionHandler: { _, error in if let error = error as NSError? { fatalError(Unresolved error (error), (error.userInfo)) } }) container.viewContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy container.viewContext.automaticallyMergesChangesFromParent = true } } The warning is on the merge policy: Reference to var 'NSMergeByPropertyObjectTrumpMergePolicy' is not concurrency-safe because it involves shared mutable state; this is an error in the Swift 6 language mode I have no idea how to make this concur

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
