Error message - RNFirebase core module was not fou

Question

React Native Firebase won’t install on iOS React Native project. It works fine on Android.

I followed this instruction. https://rnfirebase.io/docs/v5.x.x/installation/initial-setup I set up Firebase, added the downloaded plist file via XCode, installed and set up Cocoapod.

The moment I add the following line to my App.js, the simulator returns an error message.

  import firebase from 'react-native-firebase';

The error message: “RNFirebase core module was not found natively on iOS”

I’ve tried a few things I picked up from this forum: https://github.com/invertase/react-native-firebase/issues/614

I commented out following lines from Podfile

use_frameworks!

And then pod install, pod update

on Xcode, checked the Build Phases/ Link Binary with Libraries section. I checked libRNFirebase.a was already there.

I've been trying this for a few months now on and off. And I haven't found a way to make React Native Firebase install on iOS project. Any pointer would be much appreciated.

Answer 1

I'm currently maintaining the react-native-firebase v5 branch (current stable) and we do have a problem with the header search paths right now for some reason.

I don't have a definitive fix, but I constructed a demo that goes from react-native init, then installs react-native-firebase, and does all the things necessary such that the project builds and runs on iOS and even archives in release mode.

The only thing that is important at the moment is that you need to put one non-documented thing in your Podfile after following all the install instructions, as the last line before the final end

  system("mkdir -p Pods/Headers/Public/FirebaseCore && cp Pods/FirebaseCore/Firebase/Core/Public/* Pods/Headers/Public/FirebaseCore/")
