I want to prompt users when their iCloud storage quota is full. My test device's iCloud space is full, and when subscribing to the NSPersistentCloudKitContainer-eventChangedNotification event, events exceeding the quota will not be passed to the application at runtime.

When I tried to add data to Core data using NSPersistentCloudKitContainer, I got an error:

My iCloud storage space is full, but I am unable to retrieve the 'Quota exceeded' error.I have written a demo, please help me fix the issue.

I posted about the same issue before and also filled feedback. But this is still an issue: https://developer.apple.com/forums/thread/830420

Thanks for reporting the issue. Yeah, this is a known issue: (CKError 25/2035: "Quota Exceeded") is nested inside the CloudKit operation's internal partial failures dictionary, and NSPersistentCloudKitContainer does not preserve or populate partialErrorsByItemID (or CKPartialErrorsByItemIDKey in userInfo) on the public Event.error object delivered through eventChangedNotification.

I’d still suggest that you file your own feedback report to voice the impact, which may help the framework folks to prioritize the issue.

Before the issus is fixed from the framework side, the only workaround I can see is that you use CloudKit API directly to write data to the CloudKit database, detects and handle the CloudKit error, if any, and then remove the data. This is obviously far from ideal, however.

Best,
