title: How do I convert CoreLocation coordinates to a String?
body: <pre><code>func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
      var user_lat = manager.location.coordinate.latitude
      var user_long = manager.location.coordinate.longitude
      self.locationManager.stopUpdatingLocation()
  }
  </code></pre>
  
  <p>I've tried <code>String(manager.location.coordinate.latitude)</code> but that doesn't seem to work.</p>
