The skill

Helps write and check SwiftUI apps for Apple devices.

Only when you ask.

Fewer bugs

Every code change is checked for old and wrong code. Fewer bugs.

↻ Runs by itselfevery time Swift code changes

How the habit works.
You don't have to.

Three questionsWhen does it start? How does it check its work? What does it remember?

01

It starts by itself

PR changes Swift files. Runs in GitHub Actions or Claude Code routine.

  • ↻ PR changes Swift files
  • pull_request paths: **/*.swift

02

It checks its work

checklist passes. If a check fails, it tells you.

  • ✓every @State and @FocusState property is private
  • ✓no ForEach uses .indices or \.offset
  • ✓every .animation call has a value parameter

03

It remembers

review findings log. The next run reads it first: soft-deprecated APIs flagged before and open findings.

loops/swiftui-review-loop/findings.md

One run, step by step.
Then it stops.

Stop ruleStops after one pull request per run.

  1. 01

    Read the change

    Read the Swift files and pick the topics that apply.

  2. 02

    Route topics

    Open the matching reference from the topic router for each one.

  3. 03

    Check APIs

    Compare against latest-apis.md, replace hard-deprecated APIs and flag soft-deprecated ones.

  4. 04

    Check gating

    Make sure version-specific APIs use #available with fallbacks.

  5. 05

    Run the checklist

    Walk the correctness checklist for state, ForEach, environment and animation.

  6. 06

    Report

    List findings and give performance ideas as suggestions only.

What it may do.
Nothing more.

Safe by defaultIt writes only in its own folder and asks you before anything goes out.

Is it for you?
Use it when it fits.

Quick checkRead both lists. If the left one sounds like you, the SwiftUI Expert Skill skill helps.

Use it when

  • ✓ You review or refactor SwiftUI code
  • ✓ You migrate deprecated SwiftUI APIs
  • ✓ You analyze an Instruments trace

Skip it when

  • – The app is UIKit only
  • – You need server-side Swift
