title: Displaying a Map with MapKit in a Swift playground for a Quick Look?
body: <p>Good to see a tag for swift-playground - love to see this continue.</p>
  
  <p>I've been tinkering with Swift and am wondering whether the MapKit can be used in the playground so that you can use the Quick Look feature so I can iterate and play around with a preview of my work.   I haven't figured out the syntax so thought I would ask if anyone has explored this in a playground environment.  I am thinking I need some code to establish it as a view controller.</p>
  
  <pre><code>import UIKit
  import MapKit
  
  // Sample UIView code which works great in the playground.
  //var myView:UIView = UIView();
  //myView.frame = CGRectMake(0, 0, 320, 560)
  //myView.backgroundColor = UIColor.blueColor()
  
  // Non working map code - no errors but can't figure out what to call or initiate to get the view in the Quick Look side.
  
  var mapView = MKMapView();
  mapView.region.center.latitude = mapView.userLocation.coordinate.latitude;
  mapView.region.center.longitude = mapView.userLocation.coordinate.longitude;
  mapView.region.span.latitudeDelta = 0.00725;
  mapView.region.span.longitudeDelta = 0.00725;
  </code></pre>
  
  <p>Guessing I am just missing something simple for the mapView to init itself etc.  I love the interpreted playground area for tinkering around, just need to figure out if it can do mao functionality as opposed to just writing .swift files and environment within Xcode and getting more formal.</p>
