React Native just reinitialize iOS or Android Project

Question

I want to start again building my React Native app with iOS because I messed up the XCode Project and can't make it build. How can I just reinitialize the iOS project or in other cases the Android Project in my existing React Native app?

Answer 1

It seems that this functionality was once implemented in react-native with the command react-native ios or react-native android, which are no longer implemented. But I found a solution for Android here which is also working for iOS:

const fs = require('fs');
const generate = require('react-native/local-cli/generate/generate.js');

generate([
  '--platform', 'ios', //or android
  '--project-path', process.cwd(),
  '--project-name', JSON.parse(
    fs.readFileSync('package.json', 'utf8')
  ).name,
]);

Just put this code in a script and run it with node script-name.js
