title: Swift 5 - how to create a tab bar with a centre circle button? | noob here
body: <p>New to Swift and Stack Overflow! Found similar post(s), though the answers were still not enough guidance for me to figure it out. So would really appreciate if a bit more detailed guidance can be provided.</p>
  <p>I would like to create a tab bar with 5 tab items, with the middle tab item essentially a centre round add button similar to this:</p>
  <p><a href="https://i.stack.imgur.com/YwTyq.png" rel="nofollow noreferrer">Example</a></p>
  <p>I have seen a post that seems to suggest that I don't need to use an actual button element, as I can just change the icon to white when the icon is selected, and create a circle in the background of the middle tab item...Except I'm so new to this that I cannot figure out how to do either. I've only managed to customise tab colors when the item is active or inactive.</p>
  <p>Can anyone help please?</p>
  <p>Sorry it's a basic question. Much appreciated for your input.</p>
