Yeah, the prompt is just asking Claude to generate a SwiftUI iPhone app. The recent models have been able to generate really good Swift code, so we just have a set of best practice instructions we've been accumulating (telling it to make an app with @main, pointing it to/away from some APIs, encouraging it to persist things in UserDefaults, etc).

I think most of that would work pretty well for making SwiftUI desktop apps too.

It would be lovely if the community had this knowledge about API's to avoid and approached to adopt. SwiftUI programming is a tightrope walk of stuff that works over a chasm of time lost to testing.
