title: Cannot assign CGPoint to CLLocationCoordinate2D
body: <pre><code>var touchPoint = gestuRerecognizer.locationInView(self.map)
  var newCoordinate = map.convertPoint(touchPoint, fromCoordinateSpace: self.map)
  var annotation = MKPointAnnotation()
  annotation.coordinate = newCoordinate
  </code></pre>
  
  <p>This code gives me (<strong>Cannot assign a value of type 'CGPoint' to a value of type 'CLLocationCoordinate2D'</strong>) error.</p>
