On the page you link to with the video, there is a Resources section with a link to "Building a document-based app using SwiftData". This page has a download for the sample project code - https://developer.apple.com/documentation/SwiftUI/Building-a-document-based-app-using-SwiftData. Gavin

Might be too late now, but this worked for me: https://gist.github.com/JadenGeller/afb907745865052ed59c53b5ca9f8671 Update: I've just notice this Xcode debug warning when running the app: Presenting view controller <PHPickerViewController: 0x103240080> from detached view controller <UIViewController: 0x1036bcca0> is not supported, and may result in incorrect safe area insets and a corrupt root presentation. Make sure <UIViewController: 0x1036bcca0> is in the view controller hierarchy before presenting from it. Will become a hard exception in a future release. So it might not be a viable solution Cheers Gavin
