React Native warning: RCTC module not exported

Question

I am getting a warning when running my React Native app on iOS:

Class RCTCxxModule was not exported. Did you forget to use RCT_EXPORT_MODULE()?

How can I fix this?

Answer 1

This occurs with RN 0.55.3 and probably any newer version.

For now it's not the best solution, but to avoid the warning we can ignore it:

import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['Class RCTCxxModule']);
