title: CLFloor returning nil in iOS 8
body: <p>So I am trying to get CLFloor in Core Location to give me data instead of returning nil in Swift, but I have not been able to. I have tried my own code and the following from NSHipster:</p>
  
  <pre><code>import CoreLocation
  
  class LocationManagerDelegate: NSObject, CLLocationManagerDelegate {
      func locationManager(manager: CLLocationManager!, didUpdateLocations locations: AnyObject[]!) {
          let location: CLLocation? = locations[0] as? CLLocation
          if let floor: CLFloor? = location?.floor {
              println("Current Floor: \(floor?.level)")
          }
      }
  }
  
  let manager = CLLocationManager()
  manager.delegate = LocationManagerDelegate()
  manager.startUpdatingLocation()
  </code></pre>
  
  <p>Does anybody know how to make this work on a device or in the simulator, I'm sure the answer would benefit a lot of people. If anyone knows of any good resources on this or CLVisit, that would also be helpful.</p>
