Apple Developer Documentation

by kimsungwhee

Search Apple's developer documentation, check what an API is available on, and read WWDC sessions as transcripts and code — without leaving the editor.

Framework & SDK Documentation LookupOfficial source
Summary
The API question and the availability question get answered in the same place.

What it takes off you is the tab-switching: a symbol you half-remember resolves to a documentation page, and the same set of calls tells you which OS versions it exists on, what replaced it if it is deprecated, and which types it depends on. WWDC is searchable as text rather than as video, so a technique demonstrated on stage can be quoted rather than described.

What it is

A read layer over Apple Developer Documentation and the WWDC session archive. Searches return documentation URLs; a second call reads the page, its references and the APIs around it.

What you get
  • Search across Apple's documentation for APIs, frameworks, guides and samples
  • The full content of a documentation page, optionally with its references, related and similar APIs, and a platform analysis
  • Every Apple technology and framework by category, with beta status
  • Symbol browsing inside one framework, filtered by symbol type or name pattern
  • An API's relationships: inheritance, protocol conformances, Apple's own suggested alternatives, and every type a page references, resolved in one batch
  • Availability for an API across platforms and OS versions, including deprecations and minimum deployment targets
  • Alternatives to an API, including modern replacements for deprecated ones
  • Recent platform updates, new APIs and release notes, filtered by year, technology or category
  • Technology overviews and complete sample projects, as opposed to the snippets a search returns
  • WWDC sessions by year and topic, full-text search across every transcript and code example, and one session's complete transcript, code and resources
  • Related WWDC sessions for a video — prerequisites, follow-ups and thematically close talks
  • The WWDC code examples as a set of their own, browsable and filterable rather than buried inside the session pages
Requirements

Npx on your PATH. The WWDC transcripts and code examples ship inside the npm package rather than being fetched, so those calls answer with no network at all; the documentation calls go out to developer.apple.com live.

Setup effort

One command — npx -y @kimsungwhee/apple-docs-mcp
