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.
