Local Storage Diagnostics for iOS FAQs

Question 1

Is the iOS file system unreliable for saving data?

Accepted Answer

No, the iOS file system is battle-tested. 99% of storage issues stem from incorrect location choices, protection level mismatches, or missing backup exclusions.

Question 2

How do I fix 'No permission' errors for background tasks?

Accepted Answer

Files with .complete protection are inaccessible when the device is locked. Change the protection level to .completeUntilFirstUserAuthentication to allow background access.

Question 3

When should I use the axiom-storage-diag skill?

Accepted Answer

Use it whenever you encounter 'file not found,' storage full errors, or data persistence issues during xOS app development.

Question 4

Why do my files disappear after an iOS device restart?

Accepted Answer

This usually happens when files are stored in the /tmp/ directory, which iOS purges upon reboot. Moving persistent data to Application Support or Documents resolves this.

Question 5

Why is my app's iCloud backup so large?

Accepted Answer

Large re-downloadable content in Documents or Application Support often causes bloat. Use isExcludedFromBackup = true for these files or move them to the Caches directory.
