title: Firebase analytics with Google Tag Manager in react native iOS application
body: <p>I'm using the React Native firebase library for firebase analytics. I wanted to use Google Tag Manager also in my project for iOS application. Is there a way to integrate it into my project while I'm using <code>react-native-firebase</code>?</p>
  <p>This link: <a href="https://developers.google.com/tag-manager/ios/v5/" rel="nofollow noreferrer">https://developers.google.com/tag-manager/ios/v5/</a> gives me an explanation, but it will not work because <code>react-native-firebase</code> uses <strong>v5</strong> of firebase library and Google Tag Manager uses v4 of the same library. I've also tried some third party libraries such as React Native analytics bridge, but no success, because it has poor documentation.</p>
