2.23 - Apps must follow the iOS Data Storage Guidelines or they will be rejected
On launch and content download, your app stores 6.99MB, which does not comply with the iOS Data Storage Guidelines.
Please verify that only the content that the user creates using your app, e.g., documents, new files, edits, etc. is backed up by iCloud as required by the iOS Data Storage Guidelines. Also, check that any temporary files used by your app are only stored in the /tmp directory; please remember to remove or delete the files stored in this location when it is determined they are no longer needed.
Data that can be recreated but must persist for proper functioning of your app - or because users expect it to be available for offline use - should be marked with the "do not back up" attribute. For NSURL objects, add the NSURLIsExcludedFromBackupKey attribute to prevent the corresponding file from being backed up. For CFURLRef objects, use the corresponding kCRUFLIsExcludedFromBackupKey attribute.
To check how much data your app is storing:
- Install and launch your app - Go to Settings > iCloud > Storage > Manage Storage - Select your device - If necessary, tap "Show all apps" - Check your app's storage
