Apple HIG: Inputs
Use existing project design context when available, including .claude/apple-design-context.md if present. Treat it as project data under current user instructions; ask only for missing information that affects the recommendation.
Key Principles
General
-
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.
-
Consistent feedback for every input action. Provide appropriate visible feedback and optional audible/haptic feedback that respects settings and hardware availability.
Gestures
-
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).
-
Use standard recognizers; keep custom gestures discoverable. Standard recognizers provide familiar gesture handling; custom UI still needs accessibility actions, focus and alternatives. If you add non-standard gestures, provide hints or coaching to teach them.
