If you have solved this problem, please let me know

It has been several months now, and it seems that Apple engineers are not very concerned about this issue. I have submitted a question to Apple's technical support, but have not received any response

I also encountered this error, have you fixed the problem? My iCloud storage space is full, but I am unable to retrieve the 'Quota exceeded' error. When I tried to add data to Core data using NSPersistentCloudKitContainer, I got an error: <CKError 0x600000c15890: "Quota Exceeded" (25/2035); server message = "Quota exceeded"; op = 1ECF73B9554DF79F; uuid = 34D12DF0-A307-49EB-AD3A-BB646FF66F54; Retry after 316.0 seconds> }>
