I have done lots of SwiftUI before, so it may have helped me recognize when it goes off the rails. But I definitely don't do anything fancy with my prompting.

But for stuff like TCA (Swift composable architecture), I basically created a TCA.md file and pasted in a bunch of docs and examples and would reference that.

But for the most part, it was one shotting swiftui screens that were nicer than what I had in my mind.
