# HIG reference lookup

Generated by `scripts/pull-hig.mjs` on 2026-09-22 from developer.apple.com. Do not edit by hand; re-run the script instead.

123 guideline files live in `references/hig/`, one per page of Apple's Human Interface Guidelines that applies to iOS, iPadOS, or macOS. Each file keeps Apple's text and headings, relabels platform headings by device class (phone, tablet, mobile, desktop), and omits guidance that only applies to tvOS, visionOS, or watchOS. Load only the files a review needs; the "Covers" column is Apple's own summary of the page.
