title: how to reuse the bar button for the slide menu on every controller view
body: <p>I've built a slide menu that works fine. Each button leads to a new view controller. Rather than clicking on the back button of the subview view contoller to return to the main view controller to switch to the next function, I'd like from every view controller to have the same sliding menu.</p>
  
  <p>I want in the image below to replace "&lt; Test app" with my sliding menu icon pointing to the same menu as the main one.</p>

  <p>I've read <a href="https://stackoverflow.com/questions/42922219/sliding-menu-on-every-view-controller-in-swift">Sliding Menu on every view controller in swift</a> but it's still unclear. I'm new to xcode/ios.</p>
  
  <p>I can't find some good doc on how to do that. Where can I find doc, tuto for what I would like to do?</p>
