+- We fixed an iOS crash in encrypted storage by correcting native error handling, so Keychain failures no longer trigger an unrecognized selector abort.
+- We changed iOS Keychain item accessibility to After First Unlock for encrypted storage and persisted session cookies.
+- We added a required one-time Keychain migration to update existing stored items; for compatibility, this Native Template version still works with older Studio Pro 10.24.x, but migration support requires Studio Pro 10.24.16 or newer plus a new iOS app build and rollout. Without migration, the original Keychain accessibility issue can still occur, although improved error handling reduces crash impact.
