Basically, we are use firebase for getting real-time data or when we want to do authentication, database, etc. also firebase comes with push notification, analytics, crash reports and much more, thatʼs why every developer would love to integrate it to his app. so letʼs start with adding firebase to our project for getting firebase device token to send a notification in iOS

Create a project on Firebase:

Go to Firebase Console and add your project, Now got to firebase console then in side menu click the gear icon then right-click select the project setting then general tab then add an app, now the screen is look

  • Now project setup with firebase is completed, letʼs go to the next step.

Adding Path Setup for Firebase library to your iOS app:

Click on the project then build setting then find header search path and Added ‘$(SRCROOT)/ Firebase’ to Framework Search Paths and Heder Search Paths.

Adding a Firebase library to your iOS app:

The command for installing the library:

npm install --save react-native-firebase

Then need to link the library with our react-native project(if your react-native version is less than 0.60):

react-native link react-native-firebase

Adding Firebase pod to your iOS app:

Pod file code:

First delete the podlock file and pod folder then paste these code

 pod 'Firebse'
 pod 'Firebse/Anlytics'
 pod 'Firebse/Auth' pod 'Firebse/Core'
 pod 'Firebse/Messging' ,


pod 'RNFirebse', :path => '../node_modules/rect-ntive-firebse/ios/ RNFirebse.podspec'

After this runs the command

Go to within iOS folder and type
pod install

Setup Xcode for iOS app:

Adding GoogleService-Info.plist in Xcode, for this, you need to right-click on the name of the project looks something like.

  • In my project, its already added so it is hidden. Now you need to open the library folder and check for RNFirebse library if it not added here then, we follow the below step to dd it manually if it added here then no need to do this step.
  • Open Xcode -> right-click on name of project->select the option add files, screen looks.

  • Add the Xcode project if already itʼs not added in your Xcode -> library, Then, open a new screen which looks like.

  • And one more important thing is please click on RNFirebse.xcodeproj and click on Build Phses-> Link Binary With Libraries, now check if the FirebseCore.frmework file is already added or not if added then fine, if not added then click on + button and add these frameworks, which looks like.

Now Xcode setup is completed, if all thing going good then please go to the file where you want to access the firebase token and the import these lines.

Initialize the firebase service in AppDelegate.m iOS app:

To do this, open the AppDelegte file within your project /ios/{projectNme}/AppDelegte.m. First, we open the AppDelegte.m file then At the top of the file import the
Firebase module:

@import Firebse;
  • Within the didFinishLaunchingWithOptions method, add
    the configure method:
(BOOL)appliction:(UIApplication *)appliction
 didFinishLunchingWithOptions:(NSDictionry )lunchOptions {
 if ([FIRApp defultApp] == nil) {
 [FIRApp configure]; //add this line.

Code setup in iOS app:

import firebse from 'react-native-firebase';
var fcmToken; componentWillMount() { firebase.messaging().getToken().then((token) => {
 fcmToken = token
 console.log('fcmToken', fcmToken)

Please note:

That every time you change appʼs bundle Id whether it be iOS or Android. You will have to add a new pp in your firebase project with a new bundle Id and download the new file again.

Expected Issues:

  • Then when I try to build ‘RNFirebseUtil.h’ throws the ‘Firebase.h’ not found: error(because of header search path not set correctly).
  • “FirebseCore/FirebseCore.h” file not found from “Firebase.h”(bcoz of framework not added).
  • One more thing to check: Push notification must be on from capabilities of a project(add in firebase iOS login)
