NSPersistentCloudKitContainer

I have been excited to add NSPersistentCloudKitContainer's share functionality to my app but I've noted a few thing I suspect are bugs: -When using share() on a NSManagedObject the share record is set up in a new zone. However, the root NSManagedObject's record is not being updated with the relationship linkage to the shared record. -Secondly, when you revoke a share, the cloudkit.share record is removed from iCloud, but not in the local data stores. This makes the fetchShares() method ineffective for detecting a missing cloudkit.share record. In order to re-share the root object the developer must call out to iCloud directly using the old methods to be sure if the share exists or not. I am using the code from Apple's 'Synchronizing a Local Store to the Cloud' sample. It would be nice if they added support for revoking shares into this sample and addressed these issues.

Hello. I'm trying to setup CoreData+CloudKit integration. But I receive following errors right after NSPersistentCloudKitContainer configuration. CoreData: error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _performSetupRequest:]_block_invoke(939): : Failed to set up CloudKit integration for store: (URL: file:///var/mobile/Containers/Data/Application/18992BCF-7F0C-4271-B106-947B8F52A723/Library/Application%20Support/App.sqlite) Error Domain=NSCocoaErrorDomain Code=134060 A Core Data error occurred.

When I use NSPersistentCloudKitContainer to sync data, I receive error Code=134421/134406 Import failed because applying the accumulated changes hit an unhandled exception. iOS/iPadOS 15 beta 5 - iOS/iPadOS 15 beta 7(latest) When this error appears, data can not be import/merged from iCloud. Delete app and reinstall is not working. Same momd on macOS 12(Catalyst, with full data upgrated from macOS 11) works fine. Maybe a system bug?

I wonder if anyone has managed to get NSPersistentCloudKitContainer with a public database with a pre-seeded sqlite to work. Our app has a few thousand records held in coredata that I'd like to move to cloudkit so that when we add new data it gets shared by everyone. Currently the only way to do this is by throwing up a new version to the app store with a new sqlite database embedded inside. NSPersistentCloudKitContainer seemed like the way to go. But I cannot get it to work with pre seeded data. It seems it works fine if I download it to a device with the same apple id as added the original data. The data is there ready as soon as it's installed and new data syncs with the device. But if I install the app onto a device with a different apple id than the original seeder it deletes all the data and starts downloading it fresh from the server. This would be fine but if the data is not there when the app launches it crashes as it's critical to the app and I can't pause the app launch until it's

I receive the following error in terminal in my macOS and iOS targets that crashes a universal app written entirely in swiftUI. [General] -[NSAlert runModal] may not be invoked inside of transaction begin/commit pair, or inside of transaction commit (usually this means it was invoked inside of a view's -drawRect: method.) App structure is Sidebar Menu + Master List + Details using Core Data for persistence and Cloudkit NSPersistentCloudKitContainer for backup / mirroring. There seems to be a lot of activity prior to the crash relating to IMKInputSession CFRunLoopObserver. The crash seems to be associated with a Picker view within the detail view and whether it is First Responder at the time another item in the list is selected or a new item is added to the list (from the toolbar). Apple has suggested that... It seems that the app is presenting an alert in response to SwiftUI updating views. That use of -presentError: should be deferred outside of that immediate update (e.g. adding an observer block t

Background I have an established app in the App Store which has been using NSPersistentCloudkitContainer since iOS 13 without any issues. I've been running my app normally on an iOS device running the iOS 15 betas, mainly to see problems arise before my users see them. Ever since iOS 15 (beta 4) my app has failed to sync changes - no matter how small the change. An upload 'starts' but never completes. After a minute or so the app quits to the Home Screen and no useful information can be gleaned from crash reports. Until now I've had no idea what's going on. Possible Bug in the API? I've managed to replicate this behaviour on the simulator and on another device when building my app with Xcode 13 (beta 5) on iOS 15 (beta 5). It appears that NSPersistentCloudkitContainer has a memory leak and keeps ramping up the RAM consumption (and CPU at 100%) until the operating system kills the app. No code of mine is running. I'm not really an expert on these things and I tried to use Instruments to see i

NumberFormatter does not function as expected under Xcode 13 betas or macOS 12 betas (currently up to beta 5 for both). I've logged feedback to Apple FB9423179. I'm writing a SwiftUI universal app with macOS and iOS targets using Core Data and NSPersistentCloudKitContainer. A Core Data Entity is an Observed Object in the code for a detail View. e.g. @ObservedObject var account: Account where Account is the class. NumberFormatter currently does not function in a TextField on macOS 12, so as a workaround I am currently using with great success: TextField(Sort Order, text: Binding( get: { String(account.sortOrder) }, set: { account.sortOrder = Int64($0.filter{0123456789.contains($0)})! } ) ) where sortOrder an entity attribute of type Optional. This works well for number entry and in my humble opinion is elegant in that it is immediately obvious what the TextField is expected to do to get the information it displays and set the information provided by the user. The only issue is that when the user makes
