title: Redefinition of module 'React' in React-RCTWebSocket.modulemap
body: <p>Good day,</p>
  <p>We have just upgraded <code>react-native</code> from <code>0.59.10</code> to <code>0.60.0</code>.
  Mainly we have been following these guides:</p>
  <p><a href="https://react-native-community.github.io/upgrade-helper/?from=0.59.10&amp;to=0.60.0" rel="nofollow noreferrer">https://react-native-community.github.io/upgrade-helper/?from=0.59.10&amp;to=0.60.0</a></p>
  <p><a href="https://mattoakes.net/react-native-upgrade-guides/upgrade-to-react-native-0.60/" rel="nofollow noreferrer">https://mattoakes.net/react-native-upgrade-guides/upgrade-to-react-native-0.60</a></p>
  <p>When it comes to Android, the upgrade process was pretty straight-forward. But my team is <strong>struggling quite a bit when doing the iOS side</strong>.</p>
  <p>After following those guides and solve some problems, we are facing one which we can not find any info about... We have been stuck in here for a while now.</p>
  <p>So, the <strong>problem is</strong>: when we build the project, the next error appears. <img src="https://i.stack.imgur.com/cowzb.png" alt="ERROR IMAGE" /></p>
  <p>Reading about some similar topics, other people of the community suggested that we may be adding the same package twice either in the <code>Build Settings</code> or the <code>Build Phases</code> in our target in the XCode project. But I can not find any of it :/</p>
  <p>I suspect that the error comes form our <code>Podfile</code>, but it looks good to me:</p>
  <pre><code>require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
  
  # Uncomment the next line to define a global platform for your project
  platform :ios, '10.0'
