title: Issues with cocoapods after upgrading Xcode
body: <p>Updated my Xcode project and my <code>IQKeyboardManager</code> cocoapod was not working. I updated it and now I get this error:</p>
  
  <blockquote>
    <p>Module file was created by an older version of the compiler; rebuild IQKeyboardManagerSwift</p>
  </blockquote>
  
  <p>Any help on how to 'rebuild' a cocopod?</p>
