React Native - npx react-native run-ios doesn't work after initializing the project

It's because of use_flipper in Podfile for iOS project.


So, I was needed to indicate Flipper-Folly version with use_flipper as

use_flipper!({ 'Flipper-Folly' => '2.3.0' })

It worked perfectly after that change.

Following Everest Climber answer

  1. In Podfile under ios/ folder

    Change use_flipper! to use_flipper!({ 'Flipper-Folly' => '2.3.0' })

  2. cd ios
  3. pod install
  4. pod update
  5. cd .. && npx react-native run-ios (to run the application)

This worked for me. Hopefully, it works for you too

This seems to be an issue in react-native 0.63, try initiating the project with --version 0.62 and it should work until they fix the bug
