I do a lot of native iOS development using Opus 4.8 (and I used 4.7/4.6 before this). I have a very hard time with this comment, were you using Opus or something else?

Same. A few months ago I pointed Opus 4.6 at a mid-size Vue app and told it to create the iOS equivalent using SwiftUI, and it nailed it. I broke the process down to phases and reviewed each phase, but within about ten days I had a functioning iOS app that had full feature parity.

That's awesome! Did you follow any sort of framework in your phasing? We to migrate our entire app so any tips would be helpful.

UI: SwiftUI (primary), UIKit (limited), PhotosUI, WebKit, MapKit, Charts

Data/Concurrency: Foundation, Combine, Observation (@Observable)

Platform: CoreLocation, UniformTypeIdentifiers

Tests: Testing (Swift Testing)

I've done the same with DS-V4-Pro, GLM-5.2, MiMo-2.5-Pro, etc. - this is a task pretty much any agentic model can handle nowadays.

(I do the reverse currently where I implement a macOS front end natively, and then just let the agent rip on porting that to an HTTP API server + React/TypeScript/HTML/CSS frontend, because it's significantly easier to have agent loops fiddle with making macOS apps than it is to fiddle with a web browser and CSS.)

Let’s face it, there is no best model for something because the input is natural language.

Some models may fit better some users‘ way of prompting.

Yeah, I think this seems more true than "X is better at iOS than Y", the way you prompt seems a lot more important, and some models react differently to the same prompts.

It's almost like there is no replacement for human expertise when we need to make usable products for other humans.

I agree. There’s no chance Grok is better than Claude Code for this. And Claude is never so badly misaligned that it gives up and switches stacks.

Given how many users there are, I can easily believe it happened to at least one person who would then repeat it as an anecdote.
