Hig Patterns

# 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.
