“NSPersistentCloudKitContainer”

Core Data with CloudKit uses a specific record zone in the CloudKit private database, which is accessible only to the current user.It's not possible to use CloudKit and CoreData with the CloudKit public database? Here is my scenario.- I have an application with two core data stores.- The first store should be synced with the public CloudKit database and NOT updated by the user.- The second store should be synced with the private CloudKit database and updated by the user.lazy var persistentContainer: NSPersistentCloudKitContainer = { let container = NSPersistentCloudKitContainer(name: MyAppName) // Create a store description for the first store let firstStoreLocation = URL(fileURLWithPath: /path/to/first.store) let firstStoreDescription = NSPersistentStoreDescription(url: firstStoreLocation) firstStoreDescription.configuration = First // Create a store descpription for the second store let secondtoreLocation = URL(fileURLWithPath: /path/to/second.store) let secondStoreDescription = NSPersiste

There are a few things about how Core Data 4 Cloud Kit initializes that I'm stuggling to understand. I've spent most of the day finally getting a schema initialized on the server, and learnt a few things along the way.Firstly, even though I have a Default configuration in my managed object model, and it has been there from day one with the option Used with CloudKit checked for true, if I create an `NSPersistentStoreDescription` and set the configuration property to Default, when I try to load the stores, it will fail, saying Unable to find a configuration named 'Default' in the specified managed object model.. If I inpsect the debug description for my ManagedObjectModel instance, it does indeed not have any reference to the string Default in it (I'm not sure if debugDescription is actually printing out the configuration names however). Why does this fail? I can only get my store loaded and the schema initialized if I remove the code that sets the configuration name to Default.The next thing that tripped me up

Trying to figure out the best way to update an CoreData app to use Cloud Kit.Right now I have a ObjectA entity defined as the top level object. There is a Photo entity that contains a Binary Data attribute for the thumbnail and a URI for the location of the full image. So bascially that setup is a lot like a CKAsset in CloudKit and CKAsset would seem to be the logical way to get the images to sync between devices.I can't find anything along those lines relating to NSPersistentCloudKitContainer though. As the model is taken from Core Data model you can't really predefine an asset attribute. So would the approach be to get the CKRecord and directly add the CKAsset that way? Would there be repercussions related to the Container if you did that?And if there is some simpler way I am missing please let me know. I am aware I can do a Binary Data attribute, I had done that earlier in the app's life and it didn't work as well as just providing the URI for the image and managing the data myself. Or would that

I am looking into using the new NSPersistentCloudKitContainer to sync some internal data for my app. Generally it works great, but I have one scenario that I cannot figure out.Here the basic scenario, there is a single record in CloudKit that created and used to keep track of some internal state. Keeping it the cloud allows for two cases: when the user open the app on another device (say an iPad) and when the user re-installs the app on the same device.If its indeed the very first time the user is using the app on any device, I need to create the record with a bunch of default initial values. I am okay with spending a little time at app startup determining if its a brand new user or an existing user installing on another device.I thought maybe observing NSPersistentStoreRemoteChangeNotification would provide a useful point in time that I can say ah ha, now I know its a new user, or an existing user. However its gets called a lot and I cannot find anything in its userInfo that gives me a definitive an

I cannot change my existing core data stack to NSPersistentCloudKitContainer because that is only a iOS 13 and later support feature but I would like to have that set for iOS 13 and later while having NSPersistentContainer for earlier versions.I have a decent amount of experience working with swift and iOS but have not ever had to do something like this for versioning and certain vars/lets on certain verions.This is my code for my coredata stack for the iOS 13 and later for NSPersistentCloudKitContainer: lazy var persistentContainer: NSPersistentCloudKitContainer = { let container = NSPersistentCloudKitContainer(name: Shopping_App) container.loadPersistentStores(completionHandler: { (storeDescription, error) in if let error = error as NSError? { fatalError(Unresolved error (error), (error.userInfo)) } }) return container }()This is my code for iOS 12 and earlier: lazy var persistentContainer: NSPersistentContainer = { let container = NSPersistentContainer(name: Shopping_App
