Of the choices given, which one identifies the iOS app sandbox container structure, and which subdirectory is MOST appropriate for storing user-generated documents that should survive an app update?
- A.Documents/ - persists across updates and is included in backups
- B.Library/Caches/ - purged by the operating system under storage pressure and excluded from backups
- C.Library/Application Support/ - persists across updates and stays out of the backup set unless the developer opts in
- D.tmp/ - cleared by the operating system between launches and left out of the backup set the user creates through Finder or iCloud
Why A is correct
