Hello, I wanted to sync my Swift Data App with iCloud. I provided default values to all my models, made very relationship between my models optional. Then, at Signing and Capabilities, I finally added Background Modes (and checked Remote notifications) and iCloud (and checked CloudKit and added a container with my bundle id). Now I receive these errors every time I run my app on a device that is connect to iCloud

CoreData: error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _recoverFromError:withZoneIDs:forStore:inMonitor:](2620): <NSCloudKitMirroringDelegate: 0x302de80f0> - Failed to recover from error: CKErrorDomain:15

Here's the debug message that appears first when I start the app

Does anyone know how to solve this issue since I have done everything exactly like mentioned in multiple tutorials and blogs?

Thanks

I'm also having the the exact same issue and get the Server Rejected error while trying to follow Apple's documentation: https://developer.apple.com/documentation/swiftdata/syncing-model-data-across-a-persons-devices

Environment: Xcode 16.1 on MacOS 15.1.

Attempted solutions:

I've tried specifying the exact container in the setup:

ModelConfiguration(schema: schema, isStoredInMemoryOnly: false, cloudKitDatabase: .private("iCloud.com.MyCompany.MyApp"))

Tried reseting the container environment.
Signed out/in of iCloud and restarted computer.
Made sure iCloud storage isn't full.
Added the CloudKit framework manually to the target.
Initialized schema manually as shown in the documentation (this causes a crash with the same error).
Tried removing the CloudKit permission from the Certificates, Identifiers & Profiles in my developer account then re-adding it.

None of that has worked, and the CloudKit dashboard doesn't show that any schema was created.

Error:

Can you try changing the CloudKit container to a completely different one? I did this and suddenly it started working.
