## What it does

The skill bundles several modules for different parts of iOS work. `coding-best-practices` covers Swift idioms, architecture such as MVVM and Clean Architecture, code quality and performance. `ui-review` checks an interface against the Human Interface Guidelines: fonts, Dynamic Type, contrast, VoiceOver. A separate `accessibility-audit` module walks through an audit step by step, including automated checks via `performAccessibilityAudit` in XCUITest and evaluation of the App Store Accessibility Nutrition Label.

Navigation and planning get their own modules. `navigation-patterns` covers `NavigationStack`, `NavigationSplitView`, `TabView`, programmatic navigation with `NavigationPath` and transitions. `app-planner` takes a concept to an architecture, or audits a project you already have. Two modules go past advice: `run-simulator` builds, installs and launches the app in the Simulator and screenshots it to verify a change, while `run-device` does the same on a physical iPhone or iPad from the command line, no Xcode GUI.

Running on hardware needs Developer Mode, pairing and code signing through `xcodebuild -allowProvisioningUpdates` — that is where people usually get stuck. The skill itself is limited to `Read`, `Glob`, `Grep` and `WebFetch`, so building and launching happen through the operational modules rather than the skill's own tools. It works in Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill ios-development -a claude-code
```
```bash
npx skills add rshankras/claude-code-apple-skills --skill ios -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ios/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ios/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill ios -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ios/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill ios -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ios/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install rshankras/claude-code-apple-skills ios
```

2. **Manually: put the files in place**
- File: `.github/skills/ios/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill ios -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/rshankras/claude-code-apple-skills --path skills/ios
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ios/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill ios -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/rshankras/claude-code-apple-skills/tree/HEAD/skills/ios/SKILL.md

## When to use it
- review Swift code against modern idioms
- check a screen against Apple HIG
- run an accessibility and VoiceOver audit
- pick a SwiftUI navigation architecture
- build in the Simulator and screenshot the result

## Example prompts
- review this screen against the Human Interface Guidelines
- run an accessibility audit on my SwiftUI code
- build the app and screenshot the screen I changed

# iOS Development Expert

Comprehensive guidance for iOS app development. This skill aggregates specialized modules for different aspects of iOS development.

## When This Skill Activates

Use this skill when the user:
- Asks about iOS development best practices
- Wants code review for iOS/Swift projects
- Needs UI/UX review against Human Interface Guidelines
- Wants accessibility audit for iOS apps
- Is planning a new iOS app
- Needs help with SwiftUI patterns for iOS
- Asks about navigation architecture (NavigationStack, NavigationSplitView, TabView)
- Wants to run/launch the app in the Simulator or screenshot it to verify a change

## Available Modules

Read relevant module files based on the user's needs:

### coding-best-practices/
Swift code quality and modern idioms for iOS.
