name	apple-human-interface-guidelines
description	Apple Human Interface Guidelines (HIG) reference for designing iOS, iPadOS, macOS, tvOS, visionOS, watchOS apps. Covers UI components, layout, accessibility, typography, navigation, inputs, and platform technologies. Use when designing Apple platform UIs, reviewing SwiftUI/UIKit patterns, or applying HIG design principles to any app.

Apple Human Interface Guidelines

Comprehensive design reference covering all Apple platforms. Use this skill when:

• Designing or reviewing UI for any Apple platform
• Implementing SwiftUI or UIKit components following Apple conventions
• Making decisions about layout, typography, color, accessibility, or interaction patterns
• Integrating Apple technologies (Apple Pay, HealthKit, Game Center, etc.)
• Applying Apple's design principles to web or cross-platform development

How to Use This Skill

1. Identify the task category (platform design, component, pattern, input, or technology)
2. Find the matching reference below
3. Load the specific reference file(s) needed
4. For cross-cutting concerns (accessibility, color, typography), load the relevant foundations reference alongside any component reference
