SwiftUI Pro makes Claude run an 11-step review of your SwiftUI code and report only real problems. Each step loads one reference file: deprecated API, views, data flow, navigation, design, resizability, accessibility, localization, performance, Swift and hygiene.

Findings come back grouped by file with the rule, a before and after snippet, and a prioritized summary. Call it with /swiftui-pro in Claude Code, or $swiftui-pro in Codex, and add a focus such as "Check for deprecated API". It bundles no scripts.

Good for

iOS and macOS developers reviewing AI-written SwiftUI
Teams modernizing old SwiftUI code with deprecated API
Developers who need accessibility and Dynamic Type checked

Questions

What does SwiftUI Pro do?

It makes Claude review SwiftUI code against a fixed 11-step list and report real problems with before and after fixes. It targets common AI mistakes such as deprecated API, inaccessible buttons and performance traps.

How do I install SwiftUI Pro?

Use the install box at the top of this page. The README also offers a Claude Code plugin route, and it notes the skills installer needs Node.

How do I run it?

In Claude Code type /swiftui-pro, in Codex type $swiftui-pro, or ask for it in plain language. You can add a focus, for example "Check for deprecated API" or "Focus on accessibility".

Does it change my code?

The skill is a review: it reports findings. During feature work it says to finish the requested change and suggest unrelated modernization separately, without applying it unasked.

Is SwiftUI Pro safe to use?

It bundles no scripts and is made of instructions and reference files. The review reports findings; if you ask Claude to apply the fixes it will edit your files, so review the diff.

SwiftUI Pro vs swiftui-expert-skill?

SwiftUI Pro is an 11-step review that loads one reference per step. The swiftui-expert-skill from AvdLee has review, improve and new-feature workflows plus Python scripts to record and analyze Instruments traces.
