# 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. ## Reference Index | Reference | Topic | Key content | |---|---|---| ...
