title: Google Analytics for iOS - manual screen tracking won't work
body: <p>I've got a problem with screen tracking on iOS. I'm doing it like it's presented in sample app from Google:</p>
  
  <pre><code>    let tracker = GAI.sharedInstance().defaultTracker
      tracker.set("My screen", value: "Value")
      tracker.send(GAIDictionaryBuilder.createScreenView().build() as [NSObject : AnyObject])
  </code></pre>
  
  <p>And it doesn't work. It's correctly tracking events though, and when I'm subclassing View Controller as GAITrackedViewController it's tracking screens. But, I don't want to subclass my view controllers just to track screens. Does anyone got an idea?</p>
