Nuts. In four hours I rebuilt an iOS app that I had spent months on before AI.

Still needs UX polishing but the code is good enough and a lot more consistent than my version.

Admittedly, it did help when the AI screwed up a piece here or there to tell it to consult the old app to see how I fixed it and do something similar. But I took a freaking day to do a tricky layout thing, and after I described it conceptually it one-shot it.

But I threw the SwiftUI stuff in the bin, if the AI is writing the code UIKit is better from a performance and ability to access more platform functionality perspective. It is buttery smooth now for pieces where SwiftUI was a bit choppy.

I only open up Xcode to press Command-R 🤣

Everything else happens in Claude Code.
