# swiftui

This skill keeps a copy of the SwiftUI documentation inside your project so the agent can grep it instead of browsing Apple's site. Handy while you wire up a screen and need a modifier's exact signature.

## What it does

The skill runs in a forked context through the `Explore` agent. It ships a set of local `.md` files: the framework overview, the `View` protocol with its modifiers, separate pages for `@State`, `@Binding` and `@Environment`, the `@Observable` macro, plus `NavigationStack`, `NavigationSplitView`, `TabView`, `List`, `Canvas` and `GraphicsContext`.

Lookup is a grep over the downloaded pages. The agent searches this skill's files first, then the other Apple skills installed alongside it, and reaches for the web only when nothing local covers the topic. In that last case it takes a path from `swiftui-overview.md` and swaps it into the `sosumi.ai` mirror: `swiftui/button` becomes `https://sosumi.ai/documentation/swiftui/button`. Grep beats a network fetch on context budget.

One file, `swiftui-overview.md`, is a 907KB index of the whole framework. That makes it good for locating a page and bad for reading whole, so the skill is built around targeted searches. Some pages carry version limits: `@Observable` needs iOS 17+, `NavigationStack` and `Canvas` also start at specific iOS versions, so check the file header before you copy an example into an older target.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Prisma-Labs-Dev/apple-skills --skill swiftui -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Prisma-Labs-Dev/apple-skills --skill swiftui -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Prisma-Labs-Dev/apple-skills --skill swiftui -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Prisma-Labs-Dev/apple-skills swiftui
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Prisma-Labs-Dev/apple-skills --skill swiftui -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Prisma-Labs-Dev/apple-skills --path skills/swiftui
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Prisma-Labs-Dev/apple-skills --skill swiftui -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/Prisma-Labs-Dev/apple-skills/tree/HEAD/skills/swiftui/SKILL.md

## When to use it
- look up how a modifier such as `font` or `padding` is declared
- pick between `@State` and `@Binding` for a piece of view data
- set up routing with `NavigationStack` or `NavigationSplitView`
- move a view model from `ObservableObject` to `@Observable`
- draw a shape with `Canvas` and `GraphicsContext`

## Example prompts
- Grep the skill for how swipe actions on a `List` row are declared and show me the file
- According to `navigationstack.md`, how do I bind a path to `NavigationStack` and pop back?
- How do I declare an `@Observable` property that redraws the view?

| [graphicscontext.md](graphicscontext.md) | GraphicsContext — drawing API used inside Canvas |

## Fetching More Docs

1. Search this skill's local `.md` files first.
2. If the topic is not here, check the other installed Apple skills you have available by their names, descriptions, or `SKILL.md` frontmatter, then grep their local files. This is faster and uses less context than fetching new docs from the internet.
3. If no installed skill has the page, use the relevant documentation path from `swiftui-overview.md` with the `sosumi.ai` Markdown mirror. For example, `/documentation/swiftui/button` maps to `https://sosumi.ai/documentation/swiftui/button`.

### Common SwiftUI Doc Paths
