title: Drupal 8 Jquery conflict once logged in
body: <p>I'm using Foundation to develop a Drupal theme and, obviously, it requires jQuery.
  When I'm logged out from Drupal everything's perfect. </p>
  
  <p>Once I log in, Drupal loads a bunch of libraries among which its own jQuery.
  This causes a conflict and breaks the site.</p>
  
  <blockquote>
    <p>Uncaught TypeError: $ is not a function</p>
  </blockquote>
  
  <p>How can I solve this?</p>
