title: How to show a map within two coordinates?
body: <p>I want to show a map between two coordinates. I have used this code for showing a rect of map that contains both the coordinates. But both my coordinates are not shown and instead it shows the area between  that two coordinates excluding the coordinates.
  what Should I do to include my two coordinates as well?</p>
  
  <pre><code>    let coordinate1 = CLLocationCoordinate2DMake(28.53, 77.39)
      let coordinate2 = CLLocationCoordinate2DMake(29.13,76.69)
      // convert them to MKMapPoint
      let p1 = MKMapPointForCoordinate (coordinate2);
      let p2 = MKMapPointForCoordinate (coordinate1);
  
      let mapRect = MKMapRectMake(fmin(p1.x,p2.x), fmin(p1.y,p2.y), fabs(p1.x-p2.x), fabs(p1.y-p2.y));
      mapView.setVisibleMapRect(mapRect, animated: true)
  </code></pre>
