title: Swift 3 - How do I create a prominent button on a tab bar (e.g. camera button)
body: <p>I am using Swift 3, Xcode 8.2.</p>
  
  <p>I want to something like this (ignore the Oscars-themed fill) where the camera button is a bit more prominent/encircled on the tab bar:</p>
  
  <p><a href="https://i.stack.imgur.com/D0q46.png" rel="noreferrer"><img src="https://i.stack.imgur.com/D0q46.png" alt="enter image description here"></a></p>
  
  <p>I assume the whole thing is an image but is that image just naturally raised off the tab bar in some way?  </p>
  
  <p>Any resources or if you can point me in the right direction would be great.  Thank you!</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I may have found another article that explains what I want to do: <a href="https://stackoverflow.com/questions/30527738/how-do-we-create-a-bigger-center-uitabbar-item">How do we create a bigger center UITabBar Item</a></p>
