“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 work on a MacOS app (which has a companion iOS app) that uses Core Data with NSPersistentCloudKitContainer. The app also supports widgets and hence there is a need to migrate the persistent store within the core data stack using replacePersistentStore( at:.... During development I recently created a new model version and added a new entity, replaced some attributes etc... Working on the iOS app is fine because deleting the app clears all the data allowing me to work with a clean slate. On MacOS, I initially thought that I could simply navigate to the app group file location, delete the .sqlite file, along with the sqlite-shm and sqlite-wal. I also went and deleted the CloudKit related files. I did all of this out of pure ignorance - my expectation was that it would give me a clean slate, but it did not. This instead gave me some unpredictable behaviour, but the app was always in a bad state. the issues I saw were; • migration failure, • sqlite errors highlighting no such column: t0 - where all the

I am trying to build a widget for iOS 14 using WidgetKit and CoreData/CloudKit instance on a new Xcode 12 project. I have added my CoreData's File Target Membership to both my app and widget I have added an App Group to my main App Target. My Persistence.swift looks like this: init(inMemory: Bool = false) { container = NSPersistentCloudKitContainer(name: test-cd) let storeURL = URL.storeURL(for: group.test-data, databaseName: test-cd) let storeDescription = NSPersistentStoreDescription(url: storeURL) container.persistentStoreDescriptions = [storeDescription] 4. My widget looks like this: struct Provider: TimelineProvider { var managedObjectContext : NSManagedObjectContext init(context : NSManagedObjectContext) { self.managedObjectContext = context } ... } @main struct test_widget: Widget { let kind: String = test_widget var persistentContainer = PersistenceController.shared.container var body: some WidgetConfiguration { StaticConfiguration(kind: kind, provider: Provider(context: persistentContainer.v

I'm a bit lost because of a problem I never experienced before, however, I have a suspicion. 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 = AppDelegate.viewContext // Create new ComposedFoodItem (1) let cdComposedFoodItem = ComposedFoodItem(context: moc) // No existing composed food item, therefore create a new UUID cdComposedFoodItem.id = UUID() // Fill data cdCo

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

Hi, I am implementing the synchronisation of SwiftData with CloudKit as described in the Apple Documentation titled - Syncing model data across a person’s devices. My app runs fine on iPhone without activating CloudKit under Signing and Capabilities option. But when activated, I get a CoreData error with a code: 134060. My app is in development stage. The following is the code snippet for your reference taken from the main structure adopting the App protocol. init() { do { #if DEBUG let schema = Schema([ Debit.self, Credit.self, ]) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) // Use an autorelease pool to make sure Swift deallocates the persistent // container before setting up the SwiftData stack. try autoreleasepool { let desc = NSPersistentStoreDescription(url: modelConfiguration.url) let opts = NSPersistentCloudKitContainerOptions(containerIdentifier: iCloud.com.sureshco.MyFirstApp) desc.cloudKitContainerOptions = opts // Load the store synchronously so it compl

Hello! I'm using NSPersistentCloudKitContainer for storing data and UICloudSharingController for sharing. Here's how UICloudSharingController is created: func share(_ record: Record, avatar: UIImage) { let controller = shareControllerForRecord(record, avatar: avatar) controller.delegate = self controller.popoverPresentationController?.sourceView = self.view controller.popoverPresentationController?.permittedArrowDirections = [] present(controller, animated: true) } func shareControllerForRecord(_ record: Record, avatar: UIImage) -> UICloudSharingController { if let share = share(for: record) { let controller = UICloudSharingController(share: share, container: self.cloudKitContainer) return controller } else { let controller = UICloudSharingController { [weak self] (controller, completion: @escaping (CKShare?, CKContainer?, Error?) -> Void) in guard let self = self else { return } self.persistentContainer.share([record], to: nil) { objectIDs, share, container, error in if let share = share { rec

I am experiencing a crash when performing a batch delete and merging changes on a Core Data store that uses NSPersistentCloudKitContainer. The crash appears to be triggered when positive fractional Decimal values are stored in a TransactionSplit entity (those values are aggregated via a derived attribute in the AccountTransaction entity). If I store whole numbers or negative fractional decimals, deletion seems to work correctly. I suspect that the issue is related to the internal representation of positive fractional decimals in conjunction with a derived attribute. Data Model Setup: Account (1:N relationship → AccountTransaction) AccountTransaction (1:N relationship → TransactionSplit), which contains a derived attribute (e.g., “splits.amount.@sum”) that computes the sum over the “amount” attribute on its related TransactionSplit objects. TransactionSplit, which contains a stored Decimal attribute named “amount” (of type Decimal/NSDecimalNumber). Steps to Reproduce: Insert sample data where each Tra

I have a SwiftUI app. It fetches records through CoreData. And I want to show some records on a widget. I understand that I need to use AppGroup to share data between an app and its associated widget. import Foundation import CoreData import CloudKit class DataManager { static let instance = DataManager() let container: NSPersistentContainer let context: NSManagedObjectContext init() { container = NSPersistentCloudKitContainer(name: DataMama) container.persistentStoreDescriptions = [NSPersistentStoreDescription(url: FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: group identifier)!.appendingPathComponent(Trash.sqlite))] container.loadPersistentStores(completionHandler: { (description, error) in if let error = error as NSError? { print(Unresolved error (error), (error.userInfo)) } }) context = container.viewContext context.automaticallyMergesChangesFromParent = true context.mergePolicy = NSMergePolicy(merge: .mergeByPropertyObjectTrumpMergePolicyType) } func save() { do { try c

In the previous version of my app, I used this pattern for previews that depended on a NSManagedObjectContext: struct ContentView_Previews: PreviewProvider { static var previews: some View { tttt let managedObjectContext = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext return ContentView().environment(.managedObjectContext, managedObjectContext) } } With the delegate gone, I've swapped to this: class PreviewData { static var persistentContainer: NSPersistentContainer = { let container = NSPersistentCloudKitContainer(name: Structure) container.loadPersistentStores(completionHandler: { _, error in if let error = error { fatalError(Unresolved error (error)) } }) return container }() static var previewContext: NSManagedObjectContext { persistentContainer.viewContext } This works for previews some of the time. For example, I have this FilteredList: import CoreData import SwiftUI protocol StructureManagedObject { static var defaultSortDescriptors: [NSSortDescriptor] { get }

I am using NSPersistentCloudKitContainer. All data sync in iCloud. And when uninstalled the app, its sync correctly. However, it's required to encrypt sensitive data. I made my password attribute Transformable. Thus work fine locally. However when I delete the app. Install again. All other attributes(String, Int) sync correctly but transformable attribute does not export/synced.Here is my Modelhttps://i.stack.imgur.com/emA4m.pngpublic class EmployeeEntity: NSManagedObject { @NSManaged public var password: NSObject? @NSManaged public var firstName: String? @NSManaged public var lastName: String? @NSManaged public var idNumber: String? @NSManaged public var modifiedDate: Date? @NSManaged public var password: String? @NSManaged public var title: String? static var entityName: String { return EmployeeEntity }}extension EmployeeEntity { static func getListItemFetchRequest() -> NSFetchRequest<EmployeeEntity>{ let request = EmployeeEntity.fetchRequest() as!

I created a blank SwiftUI project and included Core Data and Cloud Kit. By selecting Core Data and CloudKit while creating the project, Apple already included some Core Data sample code and entities in the project, and also a Persistence.swift file that contained NSPersistentCloudKitContainer code. The sample code included a SwiftUI list in ContentView, with an Add button to add timestamp to the list when pressing. **I suppose after some basic setup to the project and created the CloudKit container, the app data will auto sync and can be viewed in CloudKit dashboard, but it didn't. ** Here is what I have setup: Created the project with Core Data and Cloud Kit Haven't touch any code from the Persistence.swift file since Apple has already set it up. Also haven't touch the app struct, content view and core data entities (left all sample code untouched) Selected Automatically Manage Signing and Development Team, with a paid developer acc.

Ok, I'm having a tough time trying to figure out the missing pieces of how to integrate Core Data with CloudKit, given in this fantastic talk WWDC19 here. The only thing missing from the talk was a demo on the CloudKit Dashboard - which is an important thing to leave out, because it's completely changed!I've downloaded the CoreDataCloudKitDemo sample code, and have logged into iCloud on the simulator and set up a container in the dashboard with the same bundle id as the sample code app.When I run it, it sets up the schema on CloudKit Dashboard as expected. This is verified when I created a post in the app on the simulator, a record type of CD_Post is in the CloudKit Dashboard. That's fine, check.What it doesn't do though is upload the data. I'm just trying to verify if the data is in CloudKit Dashboard, yet when I do a query on CD_Post I get 0 results. I'm trying on the public database, but I've also tried on the private and shared database with the same results.On that note, I'm also confused about how to ac

I have a watchOS extension that I'm trying to sync to their iPhone using CoreData and CloudKit, but it doesn't seem to want to sync. I've tried a few solutions (CloudKit + CoreData on iOS and watchOS sync not working, Core data + CloudKit - sharing between iOS and watchOS companion app), but it's still not syncing. Here's my shared (it's loading in both targets) persistence code: import CoreData struct PersistenceController { static let shared = PersistenceController() static var preview: PersistenceController = { let result = PersistenceController(inMemory: true) return result }() let container: NSPersistentCloudKitContainer init(inMemory: Bool = false) { container = NSPersistentCloudKitContainer(name: My-app) if inMemory { container.persistentStoreDescriptions.first!.url = URL(fileURLWithPath: /dev/null) } let description = container.persistentStoreDescriptions.first description?.cloudKitContainerOptions = NSPersistentCloudKitContainerOptions(containerIdentifier: iCloud.com.mydomain.my-app

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
