title: Multiple Navigation Controllers with Back Buttons in Swift
body: <p>I'm making an application that has:</p>
  
  <p>Navigation Controller -> View Controller -> Navigation Controller -> View Controller -> Navigation Controller -> View Controller.</p>
  
  <p>This is making it so that there's no back button on the second view controller, only the third one, and I can't get it to appear. I'm fairly new to iOS and simply want to have a path of view controllers that the user can navigate down and back. Is there a way to add the back button to the second view controller's nav bar? Is there a better way to do this? Is it problematic to just create buttons at the top of views that perform segues?</p>
  
  <p>I found some Objective-C solutions but couldn't find anything in Swift. Thanks for your help!</p>
