# Apple HIG The visual and structural half of Apple design: what things look like, what size they are, what they're called, and how they're composed. For motion, gestures, and interaction physics, use the **apple-design** skill instead — the two are complements, not overlaps. **Target: iOS/iPadOS 26+ (Liquid Glass).** Corpus crawled from developer.apple.com, most pages stamped `2025-12-16` or later. Every reference file carries its own source URL and update date. ## How to use this skill `references/` holds 171 verbatim HIG pages (1.8 MB). **Never read them all.** Read the specific pages the task needs, and prefer the four digests below for anything numeric. ### Digests — read these first for hard values | File | Contains | | --- | --- | | `references/_specs-typography.md` | Full Dynamic Type scale (xSmall→xxxLarge, AX1–AX5), SF Pro tracking per point size, minimum/default sizes | | `references/_specs-color.md` | Every system color + gray as hex, light/dark/increased-contrast | | `references/_specs-layout.md` | Device dimensions pt+px, size classes, margins, safe areas | | `references/_specs-geometry.md` | Button sizes/padding/radii, Liquid Glass layer stack, sheet radii, standard margins. **Figma-derived — second-tier provenance, see the file header** | | `references/_index.json` | Machine-readable map of all 171 pages: slug, title, platforms, update date, table count, abstract | ### Full pages — read on demand Slug maps directly to filename: `references/buttons.md`,
