title: Swift 3 Send Location as iMessage
body: <p>I have made a classic "find-my-car-app" which saves a map location and navigates back there. I now want to implement a share button, to send a saved location via iMessage.</p>
  
  <p>I have set up a MFMessageComposeViewController, in order to send a message body with the coordinates.</p>
  
  <p>Using the URL method like: <a href="http://maps.apple.com/?ll=40.730610,-73.935242" rel="nofollow noreferrer">http://maps.apple.com/?ll=40.730610,-73.935242</a>" does work, and opens the Maps app. What I'm missing is the map thumbnail in the message.</p>
  
  <p>When sharing my location from iMessage or Maps, I get a nifty little map preview with the red pin in the message.
  Copying the iMessage link on the Mac shows, that it's sent as a VCF card, but I found no way of sending a link in VCF format via iMessage.</p>
  
  <p>Does anybody know how to get that map preview working?</p>
  
  <p>Hope my question is clear enough!</p>
  
  <p>Thanks</p>
