title: Firebase Analytics setScreenName deprecated
body: <p>In version 6.29.0 of Firebase Analytics the method</p>
  <p><code>class func setScreenName(_ screenName: String?, screenClass screenClassOverride: String?)</code></p>
  <p>is deprecated. The hint given is to <strong>Use +[FIRAnalytics logEventWithName:kFIREventScreenView parameters:] instead.</strong></p>
  <p>My question is what is the parameter for screenName? How do I rewrite my helper method:</p>
  <pre><code>import FirebaseAnalytics
  func setScreenName(_ screenName: String) {
      Analytics.setScreenName(screenName, screenClass: nil)
  }
  </code></pre>
