Apple HIG: Inputs

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

Key Principles

General

1. Support multiple input methods. Touch, pointer, keyboard, pencil, voice, eyes, hands, controllers. Design for the inputs available on each platform. On iPadOS, support both touch and pointer; on macOS, both pointer and keyboard.

2. Consistent feedback for every input action. Visible, audible, or haptic response.

Gestures

3. Standard gestures must behave consistently. Tap to activate, swipe to scroll/navigate, pinch to zoom, long press for context menus, drag to move. Don't override system gestures (edge swipes for back, Home, notifications).

4. Use standard recognizers; keep custom gestures discoverable. Apple's built-in recognizers handle edge cases and accessibility. If you add non-standard gestures, provide hints or coaching to teach them.
