title: Duplicate symbols for architecture x86_64 under Xcode IONIC IOS App
body: <p>I am building an application for IOS using the IONIC framework. It was working fine, that is, until I added this plugin <a href="https://www.npmjs.com/package/cordova-plugin-firebase-analytics" rel="nofollow noreferrer">cordova-plugin-firebase-analyticsHowever</a>. Now, I keep getting the following error:</p>
  
  <p><code>ld: 89 duplicate symbols for architecture x86_64
  clang: error: linker command failed with exit code 1 (use -v to see invocation)
  </code></p>
  
  <p>I have read the similar questions posted here but none of solutions worked. 
  Any help will be appreciated. Thanks </p>
