SwiftUI Reference

This skill provides access to SwiftUI documentation via downloaded reference files and the sosumi.ai technique for fetching additional Apple docs.

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

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

Fetching Additional Documentation

The sosumi.ai Technique

Apple's developer.apple.com uses JavaScript rendering, making it inaccessible to WebFetch. Replace

developer.apple.com

with

sosumi.ai

to get LLM-friendly markdown:

# Original (doesn't work)
https://developer.apple.com/documentation/swiftui/text

# LLM-friendly
https://sosumi.ai/documentation/swiftui/text

Downloading Docs via curl

To download any Apple documentation page:

bash

curl -sL "https://sosumi.ai/documentation/swiftui/[topic]" > [topic].md

# Examples:
curl -sL "https://sosumi.ai/documentation/swiftui/text" > text.md
curl -sL "https://sosumi.ai/documentation/swiftui/button" > button.md
curl -sL "https://sosumi.ai/documentation/swiftui/sheet" > sheet.md

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`

Beyond SwiftUI

The same technique works for all Apple frameworks:

bash

# HealthKit
curl -sL "https://sosumi.ai/documentation/healthkit"

# Core Data
curl -sL "https://sosumi.ai/documentation/coredata"

# UIKit
curl -sL "https://sosumi.ai/documentation/uikit"

# Foundation
curl -sL "https://sosumi.ai/documentation/foundation"

# Combine
curl -sL "https://sosumi.ai/documentation/combine"

# SwiftData
curl -sL "https://sosumi.ai/documentation/swiftdata"

Usage Instructions

Check downloaded files first - Grep the local
```
.md
```
files for your topic
Download if missing - Use curl to fetch specific documentation
Use WebFetch for quick lookups - For single questions where a summary suffices

Example workflow:

bash

# Looking for info on modifiers?
grep -i "padding" view-protocol.md

# Need full Text documentation?
curl -sL "https://sosumi.ai/documentation/swiftui/text" > text.md

# Quick lookup via WebFetch
WebFetch("https://sosumi.ai/documentation/swiftui/text", "How to style Text?")
