Apple Documentation Lookup
Smart router to Apple Developer documentation using the sosumi CLI.
When Auto-Activated
- Looking up Apple framework APIs (SwiftUI, UIKit, Foundation, Combine, etc.)
- Checking method signatures, availability, or deprecation status
- Exploring new iOS/macOS APIs (WWDC sessions, new frameworks)
- Verifying Swift standard library behavior
- Answering "how does X work in SwiftUI/UIKit?" questions
Tool: sosumi CLI
Installed globally via npm install -g @nshipster/sosumi.
Fetches Apple Developer documentation and WWDC video transcripts as LLM-readable Markdown.
Commands
Search for documentation
sosumi search "query" [--json]
- Returns matching docs with titles, URLs, descriptions, and types
- Use
--json for structured output when you need to pick from results
- Searches across documentation, WWDC videos, and sample code
Fetch a documentation page
sosumi fetch <url-or-path>
- Accepts full URLs or paths:
sosumi fetch /documentation/swiftui/scrollviewsosumi fetch https://developer.apple.com/documentation/swift/array
- Also fetches WWDC session transcripts:
sosumi fetch /videos/play/wwdc2024/10133
- Returns full Markdown with code examples, availability info, and API details
Workflow
Search first when you don't know the exact path:
sosumi search "ScrollViewReader" --json
Fetch the result for full details:
sosumi fetch /documentation/swiftui/scrollviewreader
Apply to implementation using project patterns from IOS_DEVELOPMENT_GUIDE.md
When to Use
| Scenario |
Action |
| Need API signature/params |
sosumi fetch /documentation/framework/type |
| Check availability (iOS version) |
sosumi fetch → look at "Available on" |
| Explore new API options |
sosumi search "topic" --json → pick → fetch |
| WWDC session reference |
sosumi fetch /videos/play/wwdcYEAR/ID |
| Verify deprecation |
sosumi fetch → check for deprecation notices |
Critical Rules
- Search before guessing - Don't assume API signatures, look them up
- Check availability - Verify minimum iOS version matches project target
- Prefer project patterns - Use sosumi for reference, but implement using project conventions (AnytypeText, Color.Text.primary, etc.)
- Cache mentally - If you fetched a doc in this conversation, don't fetch it again
