The process you need to follow is so similar to renaming a react native app. Basically you just need to run react-native upgrade
in your root project directory. For further info you can check another question here. The instructions below explains how to create another react native project based on a copied one with a new name.
- First copy the directory which your to-be-name-changed application exists. And go to your newly cloned directory.
- Change the name at
index.ios/android.js
file which is given as a parameter to AppRegistry. - Change the name and version accordingly on
package.json
- Delete
/ios
and/android
folders which are remaining from your older app. - Run
$react-native upgrade
to generate/ios
and/android
folders again. - Run
$react-native link
for any native dependency. - Finally run
$react-native run-ios
or anything you want.
