title: Why does uitabbaritem have so few available images?
body: <p>I am using uitabbaritem enumeration images:</p>
  
  <pre><code>https://developer.apple.com/documentation/uikit/uitabbarsystemitem
  </code></pre>
  
  <p>But there seem to be so few of them. Is there some other type of item that I can use also in the tab bar or am I limited to just these?</p>
