Same issue here. XCode 16.2 MacOS 15.3.2

I turned on some more logging, and this what I am seeing: Failed to get extension to fetch descriptor MyBundleID could not resolve URL while initializing a bundle record! If that clears up anything for anyone.

Thanks, I will certainly do that, but I would like to understand what this error is supposed to be saying. It is pretty opaque.

I am a recent Sequoia upgrade, and I am having challenges getting a widget to read from an app group. I have tried methods C and D as outlined here: https://developer.apple.com/forums/thread/721701. Is there anything else I may be missing?
