Apple HIG Expert

Audits and designs iOS/macOS/watchOS/visionOS interfaces against Apple's Human Interface Guidelines, including the Liquid Glass design language.

Design & UIIntermediate★ 24,151⑂ 3,405AI score 9/10Last updated: Aug 9, 2026

What it does

  • Audits Apple-platform screens against the HIG and returns a scored report (100 points, -10 per violation).
  • Ships scripts/hig_checker.py (stdlib-only) with contrast, target, and batch subcommands to actually compute WCAG contrast ratios and check 44x44 pt tap targets from a JSON file.
  • Covers Liquid Glass material hierarchy (iOS 26 / macOS Tahoe), semantic colors, Dynamic Type, and VoiceOver labeling.
  • Two modes: design from scratch (platform navigation paradigms first) or audit an existing mockup, with findings delivered bottom-line-first and tagged 🟢 tool-verified / 🟡 needs device test / 🔴 assumed.

Who it's for

  • iOS/macOS engineers building SwiftUI or UIKit apps
  • Product designers who need genuinely native-feeling Apple UI
  • Teams that want a pre-release accessibility and design QA checklist

Examples

  1. "Audit my iOS settings screen against the HIG" → 80/100 scorecard listing a failing caption contrast (3.26) and an undersized 32x32 close button.
  2. "Is #8E8E93 readable on a white card?" → computes the ratio and suggests .secondaryLabel or a darker value.
  3. "Design a new visionOS screen" → layout proposal using ornaments, gaze states, and platform-appropriate navigation.
