Xcode 27's on-disk Apple documentation vector-search SQLite DB

Xcode 27 ships Apple's docs as an on-device vector-search SQLite DB

Xcode 27's Developer Documentation component (Xcode → Settings → Components) is not a bundle of .doccarchives. It's an on-device vector-search SQLite database, the RAG index behind Xcode's AI documentation search. You can read it directly.

Why this is interesting for agentic / AI-assisted coding:

  • It's a local, queryable corpus of the installed Xcode Developer Documentation, so you can ground a coding agent on it with no scraping and no network.
