Expo iOS Designer Core Design Prompt “Design a modern, clean iOS app using Expo and React Native that follows Apple’s Human Interface Guidelines: prioritize clear hierarchy and harmony; respect safe areas; use responsive Flexbox layouts and Dynamic Type with SF Pro; support dark mode with semantic system-friendly colors; keep minimum 44pt touch targets; use native navigation patterns (tabs, stacks, modals) and standard gestures; apply Liquid Glass materials sparingly for overlays like bars, sheets, and popovers with AA contrast; add purposeful motion and gentle haptics; honor Reduce Motion and Reduce Transparency; deliver icons/splash and store assets per Apple guidance.”.

Design Rules

Safe Areas Rule Wrap screens with SafeAreaProvider/SafeAreaView to avoid notches and the home indicator; never hard‑code insets.

tsx import { SafeAreaView } from "react-native-safe-area-context";

export function Screen({ children }) { return <SafeAreaView style={{ flex: 1 }}>{children}; } 2) Typography Rule Use SF Pro Text/Display (or system) with a documented type ramp; support Dynamic Type so text scales with user settings.
