Saving any CKQuerySubscription to the private database fails in the Production environment with CKError 12 (badRequest): “attempting to create a subscription in a production container”. The same subscriptions save fine in Development. The schema, including the needed QUERYABLE index, has been deployed to Production. This looks like the same issue as FB22867235 and Developer Forums thread 826814. Container: iCloud.com.darkstardev.chorecalendar Environment: Production (TestFlight build 0.2 (5)) Device / OS: iPhone18,2, iOS 27.0.1 App: Core Data with NSPersistentCloudKitContainer (private and shared stores), sharing a zone with CKShare Database: privateCloudDatabase of the share owner’s account Zone: the Core Data share zone, com.apple.coredata.cloudkit.share.7653A214-0824-4D0D-BC02-4270E0826376 Subscription: CKQuerySubscription on recordType CD_Mark predicate CD_status == "waiting" options .firesOnRecordCreation and .firesOnRecordUpdate zoneID set to the share zone Schema: CD_Mark has a QUERYABLE index on CD_status in Production, which I verified in the CloudKit Console. All three notificationInfo variants fail the same way in Production. All three succeed in Development: An alert with titleLocalizationKey, alertLocalizationKey and alertLocalizationArgs ["CD_kidName", "CD_choreName"] A plain alert with titleLocalizationKey and alertLocalizationKey, without args A silent subscription with shouldSendContentAvailable = true and desiredKeys Because even the silent subscription is refused, the cause isn’t the alert configuration. Production refuses CKQuerySubscription creation for this container. Steps to reproduce: Install the TestFlight build, signed in as the share owner. Create and share a family record through NSPersistentCloudKitContainer. Turn on the in-app setting that saves the subscription. Expected: the subscription is saved, and a push arrives when a participant creates or updates a waiting CD_Mark record. Actual: all three saves fail. Error text: “Error saving record subscription with id check-ins-com.apple.coredata.cloudkit.share.7653A214-0824-4D0D-BC02-4270E0826376 to server: attempting to create a subscription in a production container” (CKError 12). Already tried: Deploying the schema from Development to Production. Turning the setting off and on again a day later.
