关于

This skill provides Apple's Human Interface Guidelines for design foundations like colors, typography, accessibility, and dark mode. Use it when developers ask about implementing system styling, ensuring accessibility, or resolving visual design issues in their apps. It covers core visual and inclusive design principles, cross-referencing other HIG skills for specific components or patterns.

Apple HIG: Design Foundations

Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.

Key Principles

Prioritize content over chrome. Reduce visual clutter. Use system-provided materials and subtle separators rather than heavy borders and backgrounds.
Build in accessibility from the start. Design for VoiceOver, Dynamic Type, Reduce Motion, Increase Contrast, and Switch Control from day one. Every interactive element needs an accessible label.
Use system colors and materials. System colors adapt to light/dark mode, increased contrast, and vibrancy. Prefer semantic colors (label, secondaryLabel, systemBackground) over hard-coded values.
Use platform fonts and icons. SF Pro, SF Compact, SF Mono by default. New York for serif. Follow the type hierarchy at recommended sizes. Use SF Symbols for iconography.
Match platform conventions. Align look and behavior with system standards. Provide direct, responsive manipulation and clear feedback for every action.
Respect privacy. Request permissions only when needed, explain why clearly, provide value before asking for data. Design for minimal data collection.
Support internationalization. Accommodate text expansion, right-to-left scripts, and varying date/number formats. Use Auto Layout for dynamic content sizing.
Use motion purposefully. Animation should communicate meaning and spatial relationships. Honor Reduce Motion by providing crossfade alternatives.

Applying Foundations Together

Consider how principles interact:

Color + Dark Mode + Accessibility -- Custom palettes must work in both modes while maintaining WCAG contrast ratios. Start with system semantic colors.
Typography + Accessibility + Layout -- Dynamic Type must scale without breaking layouts. Use text styles and Auto Layout for the full range of type sizes.
Icons + Branding + SF Symbols -- Custom icons should match SF Symbols weight and optical sizing. Brand elements should integrate without overriding system conventions.
Motion + Accessibility + Feedback -- Every animation must have a Reduce Motion alternative. Motion should reinforce spatial relationships, not decorate.
Privacy + Writing + Onboarding -- Permission requests need clear, specific usage descriptions. Time them to when the user will understand the benefit.

Output Format

Cite the specific HIG foundation with file and section.
Note platform differences for the user's target platforms.
Provide concrete code patterns (SwiftUI/UIKit/AppKit).
Explain accessibility impact (contrast ratios, Dynamic Type scaling, VoiceOver behavior).

Questions to Ask

Which platforms are you targeting?
Do you have existing brand guidelines?
What accessibility level are you targeting? (WCAG AA, AAA, Apple baseline?)
System colors or custom?
