title: Convert MKMapPoint to NSValue in Swift
body: <p>I want to convert an MKMapPoint to a NSValue. In Objective-C i can do it with the following statement:</p>
  
  <pre><code>MKMapPoint point = MKMapPointForCoordinate(location.coordinate);
  NSValue *pointValue = [NSValue value:&amp;point withObjCType:@encode(MKMapPoint)];
  </code></pre>
  
  <p>How can i do that in Swift?
  Thanks!</p>
