I think the way humans divide up design and programming are broadly correct. Working that way with LLMs seems to work well.

I vibe coded an iOS conference schedule app recently, built on top of my own rust UI framework. I started with claude design. I gave it the requirements, and showed it screenshots of other conference schedule apps I like which have features I want to use. I also gave it some visual references for how I want the app styled. It came up with some workable designs. They were a bit 'webby'. But, fine. The high level breakdown of UI screens and navigation between them was excellent.

Then I gave all the HTML files it produced to claude code, along with the documentation for my UI framework and told it to port the code to my UI framework. The first working version was rough. It copied a lot of the unintentional webby look and feel. It worked around missing features in my UI framework by rolling its own janky reimplementations of platform features. For example, instead of using UINavigationController, it rolled its own. It made its own (kinda bad) tab based navigation bar. The app didn't work properly in dark mode, because it was hard-coding a lot of colours. It took a bit of back and forth to fix all of this stuff. But I'm really happy with it now. It looks and feels great.

It's just a pity I couldn't share the app at the conference. Apple took a few days to approve the app in Testflight, and by the time they approved it, the conference was over.

I assume everyone else is playing with the same AI tools that I am, and getting similar results. But a lot of people I talk to seem to have no idea that this is possible right now. They're amazed when I show them my schedule app.
