Same authentication problem here. Surely 14.2 is buggy.

I have the same problem. After changing data structure, I'm getting "SwiftData Fatal error: failed to find a currently active container". @beninzi, how do you delete the app and 'let Xcode recreate it?" Thank you

@OpExNetworks I have a similar issue. What did you do for 'Making the model container shared across the app solved the problem' ? Thank you.

Is there any progress or workaround? startAccessingSecurityScopedResource helps with files created by the app, but whenever I try to open the same file, but modified externally (by other computer) or try to open any arbitrary file, I can't. Hitting 'unknown client' with 'permission denied'.

Thank you, Barry and DMG for this input. It has literally been driven me nuts :) Helped a lot!
