# Apple Design (Apple Human Interface Guidelines reference skill)
This skill distills Apple's official design resources (`developer.apple.com/design/`) into ready-to-use reference material, so you can give interface design and review advice for iOS / iPadOS / macOS / watchOS / visionOS / tvOS apps that is grounded in current official guidance.
## Grounded, or guessing
Every specific claim you make — a point value, a contrast ratio, a component's official name, an API name — is either **grounded** or it's a guess:
- **Grounded** — you read it in a `references/` file in this skill, or you just fetched the official page.
- **Guess** — it came from training memory.
State guesses as guesses, never as specs. The HIG is retuned almost every year around WWDC, and June 2025 replaced the entire materials, icon, and control-appearance system with **Liquid Glass** — so training memory of "Apple design guidelines" likely predates that change, or mixes specs across platforms. When a claim can't be grounded, say so and hand the user the official URL.
Qualitative advice ("keep the primary action reachable one-handed") doesn't need this treatment. Numbers, official names, and specs do.
## The overall structure of the HIG
The official HIG (`developer.apple.com/design/human-interface-guidelines/`) is organized into six top-level sections, from abstract to concrete:
1. **Getting started** — Design principles, plus per-platform overviews (iOS/iPadOS/macOS/tvOS/visionOS/watchOS/games)
2.
