React-native-fcm: Module 'FirebaseCore' not found when building project

[martinarroyo]

I have recently upgraded an app from 2.2.0 to 2.5.1 and I have stumbled upon the following error when building RNFIRMessaging.m: Module 'FirebaseCore' not found when trying to @import FirebaseCore;.

Oddly enough, if I replace that line with @import Firebase; the build succeeds and the push notifications work. I could also reproduce this issue on a newly created RN application.

I have tested this on React Native 0.39.1, the version of the package is 2.5.1 and I am using CocoaPods 1.1.1. Tested on an iPad Mini.

Have I missed some configuration step, or is this a known issue?

Upgrade firebase native code

[martinarroyo]

@sibelius Thank you for your reply. Can you please elaborate a bit more? I followed the steps described in the README file in a clean setup, so I am afraid I do not know what you mean. I also checked the Firebase iOS setup, only to find that the required import is actually Firebase and not FirebaseCore: https://firebase.google.com/docs/ios/setup#initialize_firebase_in_your_app

U need to download the latest firebase sdk, or run an update/upgrade on cocoapods

[martinarroyo]

Apparently that was the issue. I ran pod update and pod repo update and now it builds correctly. Thanks!

I just had the same problem, solved it by updating Firebase SDK.

I did pod update and pod redo update but I am unable to get rid of that error.

Same here. I updated manually (I'm not using cocoapods) and couldn't make it work. Still have the issue. Using ReactNative 50

Any solutions? I'm using latest versions of everything and still Module 'FirebaseCore' not found

[WundrApp]

@ramilushev I was updating from RN36 to RN50. I solved this by updating the Firebase SDK as mentioned by sibelus. For some reason (I was not the one who implemented it in the first place) I had my framework files in another directory than ios/Frameworks. I deleted the old files and put the new ones in ios/Frameworks and it worked

@ramilushev I finally got this to work by replacing the 3 lines in the file with these:

#import <FirebaseCore/FirebaseCore.h>
//import FirebaseCore;
#import <FirebaseMessaging/FirebaseMessaging.h>
//import FirebaseMessaging;
//import FirebaseInstanceID;
#import <FirebaseInstanceID/FirebaseInstanceID.h>

Not really sure what significance this has, but at least my project builds now.

@SuperDisk it is looking by header file vs looking by module.
Perhaps you Firebase modules are not in the module search path

Getting this " 'FirebaseCore/FIRApp.h' file not found " even after doing pod update and pod repo update. Any solutions??

[somsin]

why this is closed still , issue is there , i tried all steps does not working any solution , still i am getting issue 'FirebaseCore/FirebaseCore.h' file not found

[evollu]

@somsin can you share an example project with your issue?

[GuillaumeLachaud]

I am having the issue since upgrading to Firebase 15.x, could be related to a recent update on Firebase's end.

Hi, are there any updates on this issue as I'm facing the problem of Module Firebase not found. Then I used the suggested workaround by Peter and now that I'm only trying to import FirebaseCoreMessaging and two others, the app won't build due to the issue this thread is based on. I'm integrating rn-fcm without cocoapods by the way.
