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.
