Apple HIG: Platform Design

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

Key Principles

1. Each platform has a distinct identity. Do not port designs between platforms. Respect each platform's conventions, interaction models, and user expectations.

2. iOS: touch-first. Direct manipulation on a handheld screen. Optimize for one-handed use. Navigation uses tab bars and push/pop stacks.

3. iPadOS: expanded canvas. Support Split View, Slide Over, and Stage Manager. Use sidebars and multi-column layouts. Support pointer and keyboard alongside touch.

4. macOS: pointer and keyboard. Dense information display is acceptable. Use menu bars, toolbars, and keyboard shortcuts extensively. Windows are resizable with precise control.

5. tvOS: remote and focus. Viewed from a distance. Design for the Siri Remote with focus-based navigation. Large text, simple layouts, linear navigation.

6. visionOS: spatial interaction. 3D environment using windows, volumes, and spaces. Eye tracking for targeting, indirect gestures for interaction. Respect ergonomic comfort zones.

7. watchOS: glanceable and brief. Information consumable at a glance. Brief interactions. Digital Crown, haptics, and complications for timely content.

8. Games: own paradigm. Free to define in-game interaction models, but still respect platform conventions for system interactions (notifications, accessibility, controllers).
