ios – @react-native-firebase/analytics setup downside after improve No Firebase App ‘[DEFAULT]’ has been created – name firebase.initializeApp()

31 July 2025

Error: No Firebase App ‘[DEFAULT]’ has been created – name firebase.initializeApp()

"@react-native-firebase/analytics": "^21.11.0",
"@react-native-firebase/app": "^21.11.0",
"react-native": "0.79.5",
"expo": "^53.0.17",

Earlier than the improve analytics used to work and there was no subject. The config was okay. After the improve we needed to change some js init code and the issues arose. Additionally it’s price mentioning that it really works on android, which leads me to consider that there could be a problem with GoogleService-Information.plist

The setup:

"@react-native-firebase/app"

is added to plugins.

each

google-services.json
GoogleService-Information.plist

are added to .env and uploaded to EXPO

analytics.js

import { getApp } from '@react-native-firebase/app'
import {
  logEvent,
  setAnalyticsCollectionEnabled,
  getAnalytics,
} from '@react-native-firebase/analytics'

const app = getApp()

export default {
  analytics: () => {
    const analytics = getAnalytics(app)
    return {
      logScreenView: params => logEvent(analytics, 'screen_view', params),
      setAnalyticsCollectionEnabled: enabled =>
        setAnalyticsCollectionEnabled(analytics, enabled),
      logEvent: (occasion, params) => logEvent(analytics, occasion, params),
      setUserProperty: (title, worth) => analytics.setUserProperty(title, worth),
    }
  },
}

App.js

import analyticsModule from './lib/analytics'

const analytics = analyticsModule.analytics()
analytics?.setAnalyticsCollectionEnabled(true)

useAuth.getState().addOnSignedInListener(() => {
  analytics?.setUserProperty('logged_in', 'true')
})

useAuth.getState().addOnSignedOutListener(() => {
  analytics?.setUserProperty('logged_in', 'false')
})

GoogleService-Information.plist

Any thought what the difficulty could be?
