title: Swift: Firebase Analytics setScreenName
body: <p>in my dashboard firebase analytics the screens are named by the name of their classes, I found a function:</p>
  
  <pre><code>Analytics.setScreenName("Pod tab", screenClass: "Pod tab")
  </code></pre>
  
  <p>I put it in the <code>viewDidAppear</code> but it still does not work, which I have to set something else?</p>
