I am trying to build the example on device model example in video WWDC26/241 (What’s new in the Foundation Models framework). I have included the coreai-models package from GitHub but the build still fails with; What’s new in the Foundation Models framework Suggestions appreciated!

I am testing an app which reads text files from the documents directory on the Vision Pro. This was working for a while. Suddenly, after some edits, renaming a file and adding new test files. I only see the old files. How can I force Xcode to use the live directory at all times for testing.
