title: 79 duplicate symbols for architecture x86_64 Xcode
body: <p>I am working in React Native project and I am trying to build the project and I am facing this error now</p>
  <pre><code>/Users/XXXX/Library/Developer/Xcode/DerivedData/XXX-cdhqlijyeqlscheswseaiojrllyn/Build/Products/Debug-iphonesimulator/`**TcpSockets**`/libTcpSockets.a(GCDAsyncSocket.o)
  ld: 79 duplicate symbols for architecture x86_64
  </code></pre>
  <p>I had like <strong>144</strong> <code>duplicate symbols for architecture x86_64</code> and my error was something like that.</p>
  <p><code>/Users/XXXX/Library/Developer/Xcode/DerivedData/XXX-cdhqlijyeqlscheswseaiojrllyn/Build/Products/Debug-iphonesimulator/</code><strong>react-native-udp/</strong><code>../.. </code></p>
  <p>and when I uninstall <code>react-native-udp</code> the duplicate symbols decreased from 144 to 79</p>
  <p>and I tried to delete the <code>TcpSockets </code> but it gets created with the build or <code>install pod</code></p>
  <p>I don't have much knowledge in Xcode so Any clues what's the problem or maybe solution ?</p>
