Hi, I’m seeing a CloudKit Production sync failure in an iOS app using SwiftData/Core Data with private CloudKit mirroring.
Sync worked correctly after release, then stopped working without any new app build being released.
Device logs show: CKInternalErrorDomain Code=1011 and Core Data reports that CloudKit mirroring was never successfully initialized.
CloudKit Production logs also show a native PRIVATE database request failing with: USER_ERROR / BAD_REQUEST involving the internal record type: _pcs_data
The Production schema, private zone, and subscription are still present. I have not reset Production or deleted any zones/subscriptions.
I have already filed a Feedback Assistant report with diagnostics.
Has anyone seen this pattern before? Is there a safe developer-side remediation, or is this typically an Apple-side CloudKit/PCS issue?
I want to avoid any destructive action that could risk existing user data.
