Creating an Expo app in 2023

12th July, 2023. I'm going to try creating an iOS app called Paranovel, using Expo. My environment for mobile app dev (Xcode, Ruby, etc.) should be in reasonably good shape already as I frequently develop with React Native and NativeScript.

Creating the app

Go to https://docs.expo.dev, and see the Quick Start: npx create-expo-app paranovel

This runs with no problem, then I get this macOS system popup:

import React, {useRef, useState} from 'react';
import {FlatList, Image, useWindowDimensions} from 'react-native';
import {Gesture, GestureDetector} from 'react-native-gesture-handler';
import Animated, {useSharedValue} from 'react-native-reanimated';

// array of 3 images
const images = [
  {id: 1, url: 'https://picsum.photos/id/237/200/300'},
  {id: 2, url: 'https://picsum.photos/id/238/200/300'},
  {id: 3, url: 'https://picsum.photos/id/239/200/300'},
