Hi,
Some of my users are experiencing synchronization issues when using the NSPersistentCloudKitContainer in CoreData.
My app is listening to any errors that occur during the synchronization with the NSPersistentCloudKitContainer.eventChangedNotification Notification.
Before I just got Cocoa-Errors 2 or 3 which indicate a bad network connection or something similar.
Now I received reports with a Cocoa-Error 134419. Does anyone know what this error code means?
Maybe someone from the Core Data team could have a look at this.
Thanks a lot,
Alexander

Starting 20th March 2025, I see an increase in bandwidth and latency for one of my CloudKit projects.
I'm using NSPersistentCloudKitContainer to synchronise my data.
I haven't changed any CloudKit scheme during that time but shipped an update. Since then, I reverted some changes from that update, which could have led to changes in the sync behaviour.
Is anyone else seeing any issues?
I would love to file a DTS and use one of my credits for that, but unfortunately, I can't because I cannot reproduce it with a demo project because I cannot travel back in time and check if it also has an increase in metrics during that time.
Maybe an Apple engineer can green-light me filing a DTS request, please.
