React-native-fcm: "Module 'Firebase' not found" while building (iOS)

[jaschaio]

I checked and the line causing the error was just updated yesterday https://github.com/evollu/react-native-fcm/commit/da07b4d2d769eb112a33b696efa324cf2892ec1d

Not sure what I am missing.

react-native: 0.53.3
react-native-fcm: ^14.0.0

[jaschaio]

Replacing the @import Firebase; line with

@import FirebaseCore;
@import FirebaseMessaging;
@import FirebaseInstanceID;

Seems to work for me.

[evollu]

@import Firebase; is how FCM official document suggests.
Probably you are missing something in pod install.

[douglasjunior]

Same problem here after update the library, I'm not using cocoapods.

[douglasjunior]

I think that @import Firebase; is not supported for all use cases yet.

In README file that is shipped with Firebase Library:

1. Drag the Firebase.h header in this directory into your project. This will
   allow you to #import "Firebase.h" and start using any Firebase SDK that you
   have.

README.md.zip

The standalone library can be downloaded here: https://firebase.google.com/download/ios

[evollu]

let me check. it is such a headache.

[evollu]

@douglasjunior can you try add module.modulemap file next to the header file?

module Firebase {
  export *
  header "Firebase.h"
}

[douglasjunior]

I also suffer with these problems in a project that I maintain douglasjunior/react-native-keyboard-manager#20 😄

About the module.modulemap file, is something like this?

Not worked too.

[vic9511]

Same problem here, I'm using cocoapods.

[andrejunqueira1]

same problem :(

[dotansimha]

same :(

[evollu]

@vic9511 cocoapod should not have problem. the example project is using cocoapods without issue

[dotansimha]

@evollu
I'm using cocoapods in my project. Updated to the latest version of react-native-fcm and since then I'm getting this error. Also tried to pod update and it didn't help.
Tried to clean everything and reinstall again - still getting this error. at the moment, the only possible workaround I found is to revert to v13...

[evollu]

@dotansimha can you compare the project with the example project? that works without issue

[vic9511]

@evollu yes you right, sorry for that. It seems that I had a conflict with linkings.

@dotansimha we fixed that closing xcode and deletting ios/Pods and Podfile.lock

Add in your Podfile just: pod 'Firebase/Messaging'

Also delete node_modules and run yarn again and run pod install as well

And re-check again Manual linkings https://facebook.github.io/react-native/docs/linking-libraries-ios.html

Maybe you can also try react-native unlink react-native-fcm to prevent other linkings conflict (although it should not affect)

Hope this can help you!

[evollu]

added example of manual integration under no-pod branch. also updated readme a bit
@douglasjunior

[douglasjunior]

Adding User Header Search Paths and creating module.modulemap made it work. Thanks.

[evollu]

@jaschaio issue seems to be solved. can i close this?

[bkvirendra]

Replacing @import FirebaseCore with the below code worked for me.

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

(note I'm integration react-native in an existing project that uses cocoapods)

[evollu]

@bkvirendra this is not a solution.
I'm not going to change it back to use #import

[kcfgl]

@vic9511 I've been struggling with this same issue for a few hours after upgrading to latest version. I've tried the manual route and the Pods route. Followed your steps and deleted nod_modules, pods, reran everything. Now Im getting some new failures which seems like progress.

@evollu Any idea what I might've done wrong now?

EDIT Disregard. I'm sorry for the noise, I solved this. I had an old framework file in my iOS folder that was causing the issue. I'm back up and running. Thanks for this library and your work

[Titozzz]

Hello, @evollu It looks like the fix to the podspec file was working for 11.3 but not anymore, I'll try to fix it so we can use the new syntax

EDIT: Spent 2 hours, still no result.

Best way right now is
@import FirebaseCore;
@import FirebaseMessaging;
@import FirebaseInstanceID;

[evollu]

@Titozzz pod solution has been working fine for me. Can you share a public repo that has the issue?

[Titozzz]

Will do asap.

[brzonsea]

I am using cocoapods and am also facing the same issue. I tried to above solutions, I also tried reinstalling and re-doing my manual linking. But still I find the 'Module Firebase not found' error.
Also,
@import FirebaseCore;
@import FirebaseMessaging;
@import FirebaseInstanceID;
replacing the line with this just simply gives out 'Module FirebaseCore not found' instead.

[bkvirendra]

@brzonsea can you try using this instead, and see if that works for you?

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

[brzonsea]

@bkvirendra
I tried it just now, and "'FirebaseCore/FirebaseCore.h' file not found" is the error message now.
Am I missing some critical step in the setup process? I think I've read the README quite thoroughly, but what are these FirebaseCore, FirebaseMessaging, FirebaseInstanceID stuff?

[bkvirendra]

@brzonsea do you have the pod 'FirebaseMessaging' in your Podfile?

Also, can you check if you have the following in Header Search Paths,

[brzonsea]

@bkvirendra
Thanks for the detailed image! I didn't have the above Header Search Paths, so I added them.
But the problem is not solved yet... And yes, I have the pod 'FirebaseMessaging' in my Podfile

[bkvirendra]

@brzonsea can you paste the detailed versions & the traceback for the exception?

[brzonsea]

@bkvirendra
My versions are
react-native: 0.51.1
react-native-fcm: ^14.1.0
cocoapods: 1.4.0

And this is the error message:

In file included from /Users/namungkim/Projects/Classum/ClassumReactNativeApp/node_modules/react-native-fcm/ios/RNFIRMessaging.m:1:

[Titozzz]

Guys, I think we have 2 separate issues here, on my side i'm taking about people linking the library with cocoapods with this kind of podfile:

target 'test' do
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'Core',
    'CxxBridge',
    'DevSupport',
    'RCTText',
    'RCTImage',
    'RCTNetwork',
    'RCTWebSocket',
    'RCTSettings',
    'RCTAnimation',
    'RCTLinkingIOS',
    # Add any other subspecs you want to use in your project
  ]

  pod "yoga", :path => "../node_modules/react-native/ReactCommon/yoga"
  pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
  pod 'GLog', :podspec => '../node_modules/react-native/third-party-podspecs/GLog.podspec'
  pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'

  pod 'react-native-amplitude-analytics', :path => '../node_modules/react-native-amplitude-analytics'
  pod 'CodePush', :path => '../node_modules/react-native-code-push'
  pod 'react-native-fbsdk', :path => '../node_modules/react-native-fbsdk'
  pod 'react-native-fcm', :path => '../node_modules/react-native-fcm'
  pod 'react-native-google-signin', :path => '../node_modules/react-native-google-signin'
  pod '....'
end

---

However you guys are using the podfile to only link the native dependencies manually:

---

target 'test' do
  pod 'Firebase/Messaging'
  pod '....'
end

The point of using method n°1 is that you only link using the cli and the dependencies are specified inside the podspec file. cc @evollu

[brzonsea]

@bkvirendra
It seems I was using the firebase web sdk, so prior native settings for firebase wasn't done. After installing react-native-firebase, and following your advice it is working now! Thanks!

[evollu]

@brzonsea for everyone having issue with
#import <FirebaseCore/FirebaseCore.h>
You are not having the latest version of the repo. This line has been updated by following
https://github.com/evollu/react-native-fcm/blob/v14.0.1/ios/RNFIRMessaging.h#L4

[Titozzz]

@evollu Issue is not fixed for users using cocoapods like me tho... Right now I did this:

in my postinstall hooks:

"sed -i'' -e 's/@import Firebase;/@import FirebaseCore;@import FirebaseMessaging;@import FirebaseInstanceID;/' ./node_modules/react-native-fcm/ios/RNFIRMessaging.h"

[evollu]

@Titozzz please post an example github repo with the issue.

[dotansimha]

@Titozzz same here... my pod file has:

  pod 'Firebase/Core'
  pod 'Firebase/Messaging'
  pod 'react-native-fcm', :path => '../node_modules/react-native-fcm'

Tried to clean and rebuild everything - still the same.

[Titozzz]

https://github.com/Titozzz/ReactNativeStarterCocoapods

To install:

cd ReactNativeStarterCocoapods
pod install

To build: Use Xcode or command line
@evollu there you go, if you don't run yarn fix-react-native-fcm, the build will fail.

[evollu]

@Titozzz will try. thanks

[evollu]

@Titozzz The problem is it is trying to build react-native-fcm as a pod project but it doesn't know how to load module map from peers. it is really tricky. do you have to do it this way?

[Titozzz]

Yes and i'm not alone, the thing is, with react native that once you add a podfile to your project, it will try to link that way and only that way. I could link manually, I could rename my podfile during the link, but I'd rather try to find a solution so that everyone is happy.

EDIT: Please note that Firebase and Google Pods are really badly packaged and it's only with cocoapods 1.4 that we can start to hope that they will fix it with static_framework option

[evollu]

@Titozzz I'm trying

#if __has_include(<FirebaseAnalytics/FirebaseAnalytics.h>)
@import Firebase;
#else
@import FirebaseCore;
@import FirebaseMessaging;
@import FirebaseInstanceID;
#endif

but it complains module FirebaseCore not found

[Titozzz]

but does it work if you only put

@import FirebaseCore;
@import FirebaseMessaging;
@import FirebaseInstanceID;

?

[evollu]

no either.
I'm using cocoapod 1.3. Do I have to use 1.4?

[dotansimha]

For me, running this as script in postinstall works:

#/bin/sh

sed -i'' -e 's/@import Firebase;/\
#import <FirebaseCore\/FirebaseCore.h>;\
#import <FirebaseMessaging\/FirebaseMessaging.h>;\
#import <FirebaseInstanceID\/FirebaseInstanceID.h>;/' ./node_modules/react-native-fcm/ios/RNFIRMessaging.h

[Titozzz]

That's weird, because on the example repo I gave you it works for me (you can patch with yarn fix-react-native-fcm). Can you check your cocoapods version and be sure you are ^1.4.0 ?

[evollu]

#if __has_include(<Firebase.h>)
#import <FirebaseCore/FirebaseCore.h>
#import <FirebaseMessaging/FirebaseMessaging.h>
#import <FirebaseInstanceID/FirebaseInstanceID.h>
#else
@import Firebase;
#endif

[evollu]

yep seems to be working for every cases. let me know

[Titozzz]

Sorry I did not pay attention to you when you said you were using Cocoapods 1.3 😢 . Cocoapods 1.4 released this new feature allowing us to use static_frameworks (http://blog.cocoapods.org/CocoaPods-1.4.0/) that I specified in the podspec file of this repo. So I guess our differences comes from here. Let me try your syntax.

EDIT:
Maybe we need to follow those:
https://github.com/firebase/quickstart-ios/issues/245
https://github.com/firebase/firebase-ios-sdk/issues/766

[evollu]

@Titozzz anyway my code above should work for you.
it is released in latest item

[Titozzz]

I can confirm that it works, thank you for the fix. Great work 🎉

[karanhashedin]

if __has_include()

import

import

import

else

@import Firebase;

endif

gives error of module firebase not found...
I have read all above comments and implemented all
but none worked for me...
I have added path of module.modulemap to header search path but it didn't help
I have not used cocoapods.
Please help asap
Thanks in advance

[hientuong]

@jaschaio: it's work for me. Thank u.

[jissree]

If you're using objective-c just drag the file firebase.h into your project

[tsku]

I saw this error due to a missed instruction in the terminal output after installing the pod:

"Please close any current Xcode sessions and use <ProjectName>.xcworkspace for this project from now on.
Pod installation complete! There are 0 dependencies from the Podfile and 0 total pods installed."

Opening the new .xcworkspace fixed it for me.

[hungvu193]

such a headache, i'm still facing this issue on Xcode 9.4, "react-native-fcm": "11.2.0". Any solutions so far 🗡

[yuber1792]

Hi

Español:

tenia una version antigua de firebase analytics la actualiza, luego npm install después pod install para terminar luego agregando estas lineas.

Ingles:

had an old version of firebase analytics update it, then * npm install * then pod install to finish then adding these lines.

import

[vickkeshri]

I found the problem with pod 'RNFirebase', :path => '../node_modules/react-native-firebase'.
Solution:
I commented pod 'RNFirebase', :path => '../node_modules/react-native-firebase'

react-native link
cd ios
pod install (install all firesbase modules)
cd ..
npm install or yarn install

Then, try adding @import Firebase
react-native run-ios

It worked for me..!!Hope this help you guys.!

[JCYOUNG123]

@import FirebaseCore;
@import FirebaseMessaging;
@import FirebaseInstanceID;

First two no problem, but the third one shows error Module 'FirebaseInstanceID' not found.

[dsouksavatd]

1. you have to install @react-native-firebase/app package instead of @react-native-firebase
2. pod install
3. yarn ios
