Apple Human Interface Guidelines interaction and UX patterns. Use this skill when the user asks about "onboarding flow", "user onboarding", "app launch", "loading state", "drag and drop", "search pattern", "settings design", "notifications", "modality", "multitasking", "feedback pattern", "haptics",

Apple HIG: Interaction Patterns Check for .claude/apple design context.md before asking questions. Use existing context and only ask for information not already covered. Key Principles 1. Minimize modality. Use modality only when it is critical to get attention, a task must be completed or abandoned, or saving changes is essential. Prefer non modal alternatives. 2. Provide clear feedback. Every action should produce visible, audible, or haptic response. Activity indicators for indeterminate waits, progress bars for determinate, haptics for physical confirmation. 3. Support undo over confirmation dialogs. Destructive actions should be reversible when possible. Undo is almost always better than "Are you sure?" 4. Launch quickly. Display a launch screen that transitions seamlessly into the first screen. No splash screens with logos. Restore previous state. 5. Defer sign in. Let users explore before requiring account creation. Support Sign in with Apple and passkeys. 6. Keep onboarding brief. Three screens max. Let users skip. Teach through progressive disclosure and contextual hints. 7. Use progressive disclosure. Show essentials first, let users drill into details. Don't overwhelm with every option on one screen. 8. Respect user attention. Consolidate notifications, minimize interruptions, give users control over alerts. Never use notifications for marketing.

Recommended pattern with rationale , citing the relevant reference file. 2. Step by step implementation covering each screen or state. 3. Platform variations for targeted platforms. 4. Common pitfalls that violate HIG for this pattern. Questions to Ask 1. Where in the app does this pattern appear? What comes before and after? 2. Which platforms? 3. Designing from scratch or improving an existing flow? 4. Does this involve sensitive actions?
