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.

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

Gestures

1. 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).

1. 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.

Apple Pencil

1. Precision drawing, markup, and selection. Support pressure, tilt, and hover. Distinguish finger from Pencil when appropriate (finger pans, Pencil draws).

1. Support Scribble in text fields. Users expect to write with Pencil in any text input.

Keyboards

1. Keyboard shortcuts and full navigation. Standard shortcuts (Cmd+C/V/Z) plus custom ones visible in the iPadOS Command key overla
