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 alter
