Apple HIG Expert

Design and audit apps against the Apple Human Interface Guidelines (HIG, developer.apple.com/design/human-interface-guidelines), including the Liquid Glass design language. HIG content evolves with each OS release — when a claim matters, verify against the live HIG pages cited in references/.

Before Starting

If product-context.md or ios-design-context.md exists, read it before asking questions. Then gather:

1. Platform target: iOS, macOS, watchOS, or visionOS?
2. Current state: new design or auditing an existing mockup/code?
3. App category: utility, productivity, game, social, etc.

Modes

• Mode 1 — Design from scratch: pick the platform navigation paradigm and layout primitives first (see references/platform-specifics.md), then apply typography and semantic color (references/visual-design.md).
• Mode 2 — HIG audit: fill in templates/hig-audit-template.md, run scripts/hig_checker.py on every measurable element, and deliver a scored report (see Worked example below).
