body: <p>I created a new app and I am trying to use <code>react-native-firebase</code>. But I continually get this error: </p>
  
  <blockquote>
    <p>RNFirebase core module was not found natively on iOS, ensure you have
    correctly included the RNFirebase pod in your projects 'Podfile' and
    have run 'pod install'. </p>
    
    <p>See <a href="http://invertase.link/ios" rel="noreferrer">http://invertase.link/ios</a> for the ios setup guide.</p>

  <p>Steps that I have done: </p>
  
  <ol>
  <li><p><code>yarn add react-native-firebase</code></p></li>
  <li><p><code>react-native link react-native-firebase</code></p></li>

  target 'MyProject' do
    # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
    # use_frameworks!
      pod 'Firebase/Core'
      pod 'Firebase/Database'
      pod 'Firebase/Messaging'
  
    target 'MyProjectTests' do
      inherit! :search_paths
      # Pods for testing
    end
