This sounds like an amazing tool/resource! Looks like I finally have a reason to try Claude Code, stoked for this!
mihaela•2mo ago
Thanks! Let me know how it goes—happy to help if you hit any issues getting it set up.

I’ve also recently been through the challenge of AI-enhanced (semantic) search. Ordering the results is very, very necessary. It’s both art and science, and absolutely requires domain knowledge.

From the article, these are the heuristics the OP applied for searching Apple documentation:

* Core types over extensions - View ranks above View+Accessibility * URL depth analysis - /documentation/swiftui/view beats /documentation/swiftui/view/some/nested/thing * Title pattern detection - Exact matches surface first * Modern over deprecated - Current APIs rank higher

mihaela•2mo ago
Totally agree—ranking is both art and science. Beyond what I listed, I'm also penalizing nested types, boosting based on query patterns ("X protocol" → boost protocols), and inferring kind from URL depth when metadata is missing.

Still actively crawling docs (at 111k now) and vector/semantic search is on the roadmap.

mihaela•2mo ago

  Update since launch:
  - 111k+ documentation pages indexed
  - 606 sample code projects (fully searchable)
  - Swift Evolution proposals, Swift.org docs, The Swift Book
  - Apple Archive legacy guides—deep conceptual docs for Core Animation, Core Graphics, Core Text, etc. that aren't in modern docs
  - 9,699 Swift packages cataloged

  Pre-built indexes available if you don't want to wait 20+ hours to crawl:
  - https://github.com/mihaelamj/cupertino-docs - Documentation archive
  - https://github.com/mihaelamj/cupertino-sample-code - Sample code mirror

Update: v0.3.0 shipped — setup is now 30 seconds

  The crawl time was the #1 friction point. Fixed it.

  cupertino setup now downloads pre-built databases from GitHub Releases. No more 20-hour crawls.

  138K+ docs pages and 606 sample projects, ready in under a minute.

  Blog post with details: https://aleahim.com/blog/cupertino-instant-setup/

This new version is awesome! I was having a problem previously where the sample projects weren't fully downloading but it's no longer an issue now! It's crazy how fast it is to setup everything in v0.3.0!
