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",
schema: schema,
url: FileManager.remoteDatabaseFolderURL.appending(path: "Remote.sqlite"),
cloudKitDatabase: .private("iCloud.com.xavimoll.abyss3"))
#if DEBUG
// Needed to create the schema on iCloud
try autoreleasepool {
let desc = NSPersistentStoreDescription(url: cloudkitConfiguration.url)
let opts = NSPersistentCloudKitContainerOptions(containerIdentifier: cloudkitConfiguration.cloudKitContainerIdentifier!)
desc.cloudKitContainerOptions = opts
desc.shouldAddStoreAsynchronously = false
if let mom = NSManagedObjectModel.makeManagedObjectModel(for: [LTRLink.self]) {
let container = NSPersistentCloudKitContainer(name: "Remote", managedObjectModel: mom)
container.persistentStoreDescriptions = [desc]
container.loadPersistentStores {_, err in
if let err {
fatalError(err.localizedDescription)
}
}
try container.initializeCloudKitSchema()
if let store = container.persistentStoreCoordinator.persistentStores.first {
try container.persistentStoreCoordinator.remove(store)
}
}
}
#endif
let localConfiguration = ModelConfiguration("Local",
schema: schema,
url: FileManager.localDatabaseFolderURL.appending(path: "Local.sqlite"),
cloudKitDatabase: .none)
return try ModelContainer(for: schema,
configurations: [cloudkitConfiguration, localConfiguration])
The logic to initialize the CloudKit schema follows the documentation found here: https://developer.apple.com/documentation/swiftdata/syncing-model-data-across-a-persons-devices#Initialize-the-CloudKit-development-schema
It looks like setting cloudKitDatabase: .none on the init for the ModelConfiguration doesn't do anything, and ends up being synced with iCloud either way. When I go to the iCloud console, I see the following:
Does anyone know if there's any workaround that would allow me to have two databases where only one of them syncs to iCloud when using SwiftData?
