One thing to call out, in my experience Coding Agents are bad a SwiftUI. Compared to doing JS frontends or any Python Backend work the difference is obvious.

I just don't think theres enough Swift in the LLMs corpus and the "right way" to do things in Swift has changes a few times in the last few years which I imagine compounds the sparse signal.

For SwiftUI work I'd personally recommend using Opus 4.5 with Axiom. Anytime you're designing something refer to Axiom, Claude needs its skills and agents to steer designs.
