iOS 14.5 App Tracking Transparency for firebase logs in react-native app

Question

Firebase logs stopped working as soon as updated to iOS 14.5 for one of the react-native app I am working on.

What are the necessary changes that we need to do to make it working again?

Answer 1

You need to request Tracking permissions first (I used react-native-permissions):

import { request, RESULTS, PERMISSIONS } from 'react-native-permissions'
import { Settings } from 'react-native-fbsdk-next'

export const requestPermissionTransparency = async () => {
  return await request(PERMISSIONS.IOS.APP_TRACKING_TRANSPARENCY)
}

useEffect(() => {
    ;(async () => {
      const result = await requestPermissionTransparency()
      if (result === RESULTS.GRANTED) {
        await firebase.analytics().setAnalyticsCollectionEnabled(true)
        await Settings.setAdvertiserTrackingEnabled(true)
      } else {
        await firebase.analytics().setAnalyticsCollectionEnabled(false)
        await Settings.setAdvertiserTrackingEnabled(false)
      }
    })()
  }, [])

Remember to add this file in the root project:

// <project-root>/firebase.json
{
  "react-native": {
    "analytics_auto_collection_enabled": false
  }
}
