title: Show distance of route
body: <p>First off, I would like to say I'm quite new to Swift. The simplest answer is probably the best in my situation.</p>
  
  <p>I currently have some code that draws a route from my current location to the Grand Canyon, using the mapkit. The starting- and ending location is build in the code:</p>
  
  <pre><code>let soucrceCoordinates = locationManager.location?.coordinate
  //coordinates off the grand canyon, placeholder
  let destCoordinates = CLLocationCoordinate2DMake(36.1070, -112.1130)
  
  let sourcePlacemark = MKPlacemark(coordinate: soucrceCoordinates!)
  let destPlacemark = MKPlacemark(coordinate: destCoordinates)
  
  let sourceItem = MKMapItem(placemark: sourcePlacemark)
  let destItem = MKMapItem(placemark: destPlacemark)
  
  let directionRequest = MKDirectionsRequest()
  directionRequest.source = sourceItem
  directionRequest.destination = destItem
  directionRequest.transportType = .automobile
  </code></pre>
  
  <p>Now I would like to calculate the distance of this route (not as the crow flies). The preferable unit would be meters. Is there anyway to do this? Thanks in advance</p>
