title: Swift 3 - How do I display borders on my camera view?
body: <p>I am using Swift 3, Xcode 8.2.</p>
  
  <p>I am trying to figure out how to display these borders on a camera feed as below: </p>
  
  <p><a href="https://i.stack.imgur.com/JunxW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JunxW.png" alt="enter image description here"></a></p>
  
  <p>I have a custom camera view that I managed to follow some tutorials for but I'd like to customize some borders to help the user frame the picture that I want them to take.</p>
  
  <p>Any help would be greatly appreciated.</p>
