React Native- Using Hermes with Flipper disabled on iOS

Question

I'm having a hard time using Flipper. I commented it out in Podfile while hermes_enabled => true. I ran pod install agin and build the app but it crashed upon launch. When I set Hermes to false, it was build successfully.

Is there a way to disable Flipper & keep Hermes true and app builds successfully?

Answer 1

For react-native v0.70.1 I did the following

1. Remove react-native-flipper from package.json. Maybe I think you need to remove other packages that depend on the flipper. But I didn't

2. Set in ios/Podfile

   :flipper_configuration => FlipperConfiguration.disabled

   instead of

   :flipper_configuration => FlipperConfiguration.enabled

3. Remove node_modules

4. Run yarn or npm install

5. Clear old data:

• 5.1 Run cd ios

• 5.2 Run command pod deintegrate && pod install

• 5.3 Run cd ..

• 5.4 Run cd android && ./gradlew clean

• 5.5 Run cd..

Clearing old data is really important, I even restart my MacBook

I hope this helps you
