Part 2

I've come from the depth of hell to require from you a part 2 of this tutorial (the first part on youtube was really really good i'm looking forward to part 2 with maybe swiftdata instead of coredata and some interesting stuff)

The issue requests a second tutorial for the Swift macOS snippet app, possibly covering SwiftData instead of Core Data, but names no files, tests, or entry points. First review the repository and the first tutorial to define the intended scope and acceptance criteria; done would be a published Part 2 tutorial with the requested interesting material.
