I work on an app that saves data to the Documents folder in the users iCloud Drive. This uses the iCloud -> iCloud Documents capability with a standard container.
We've noticed an issue where a user will delete the apps data by doing to Settings > {Name} > iCloud > Storage > App Name > select "delete data from iCloud", and then our app can no longer write to or create the Documents folder.
Once that happens, we get this error:
Error Domain=NSCocoaErrorDomain Code=513 "You don't have permission to save the file "Documents" in the folder "iCloud~your~bundle~identifier"." UserInfo={NSFilePath=/private/var/mobile/Library/Mobile Documents/iCloud~your~bundle~identifier/Documents, NSURL=file:///private/var/mobile/Library/Mobile%20Documents/iCloud~your~bundle~identifier/Documents, NSUnderlyingError=0x1102c7ea0 {Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied"}}
This is reproducible using the sample project here https://developer.apple.com/documentation/uikit/synchronizing-documents-in-the-icloud-environment.
Steps to reproduce in that project:
- Tap the plus sign in the top right corner to create a new document
- Add a document name and tap "Save to Documents"
- Go to
Settings > {Name} > iCloud > Storage > SimpleiCloudDocument App Name > select "delete data from iCloud" - Reopen the app and repeat steps 1-2
- Observe error on MainViewController+Document.swift:59
Deleting and reinstalling the app doesn't seem to help.
