  <p>I'm using <strong>ionic 3</strong> and I want to build my application in <strong>ios</strong> but it creates an issue mentioned above. </p>
  
  <p>I tried </p>
  
  <pre><code>pod install,
  pod update,
  reinstall of cocoapods,
  pod cache clean**,**cocoapods deintergrate**,**restart of my project, 
  clean and build of my project 
  </code></pre>
  
  <p>Nothing worked and I removed <strong>libpods.a</strong> files from build phase in every build of my project in Xcode,  and also I tried many solutions from various sites but till now i didn't get the solution</p>
