title: Swift 3.0 mapkit didSelect moves MKMapView to left
body: <p>I'm working on a project with swift 3.0 and a mapkit. </p>
  
  <p>Now I want to touch a Annotation </p>
  
  <pre><code> func mapView(_ mapView: MKMapView,
               didSelect view: MKAnnotationView)
  {
  
      print("Annotation touched!");
  
  
  }
  </code></pre>
  
  <p>but when I touch an Annotation the map moves to the left. </p>
