# SwiftUI Reference

This skill provides access to SwiftUI documentation via downloaded reference files.

## Downloaded Reference Files

The following Apple documentation pages are available locally (grep-friendly):

| File | Content |
|------|---------|
| [swiftui-overview.md](swiftui-overview.md) | Full SwiftUI framework index (907KB) |
| [view-protocol.md](view-protocol.md) | View protocol and all modifiers (59KB) |
| [state.md](state.md) | @State property wrapper |
| [binding.md](binding.md) | @Binding property wrapper |
| [environment.md](environment.md) | @Environment property wrapper |
| [observation.md](observation.md) | @Observable macro (iOS 17+) |
| [navigationstack.md](navigationstack.md) | NavigationStack (iOS 16+) |
| [navigationsplitview.md](navigationsplitview.md) | NavigationSplitView |
| [tabview.md](tabview.md) | TabView |
| [list.md](list.md) | List view |
| [canvas.md](canvas.md) | Canvas — immediate-mode drawing (iOS 15+) |
| [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

| Topic | URL Path |
|-------|----------|
| Text | `swiftui/text` |
| Button | `swiftui/button` |
| Image | `swiftui/image` |
| VStack | `swiftui/vstack` |
| HStack | `swiftui/hstack` |
| ZStack | `swiftui/zstack` |
| Form | `swiftui/form` |
| Sheet | `swiftui/sheet` |
| Alert | `swiftui/alert` |
| Picker | `swiftui/picker` |
| Toggle | `swiftui/toggle` |
| Slider | `swiftui/slider` |
| ProgressView | `swiftui/progressview` |
| AsyncImage | `swiftui/asyncimage` |
| GeometryReader | `swiftui/geometryreader` |
| ScrollView | `swiftui/scrollview` |
| LazyVStack | `swiftui/lazyvstack` |
| LazyHStack | `swiftui/lazyhstack` |
| NavigationLink | `swiftui/navigationlink` |
| ToolbarItem | `swiftui/toolbaritem` |
| Canvas | `swiftui/canvas` |
| GraphicsContext | `swiftui/graphicscontext` |

## Usage Instructions

1. **Check downloaded files first** - Grep the local `.md` files for your topic
2. **Use the overview as an index** - Search `swiftui-overview.md` for documentation paths
3. **Fetch only when needed** - If no installed skill has the page, use `sosumi.ai` with documentation paths from the overview

Example workflow:
```bash
# Looking for info on modifiers?
grep -i "padding" view-protocol.md

# Need full Text documentation? Check the local file first.
grep -i "font" text.md
```
