The included MKMapView extension for supporting zoom level, code belongs to Troy Brant http://troybrant.net/blog/2010/01/mkmapview-and-zoom-levels-a-visual-guide/
If you have ever built a web application using the Google Maps API, you are likely intimately familiar with this line of code:
map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13);
Simply import "MKMapView+ZoomLevel.swift" to your project.
let coordinate = CLLocationCoordinate2D(latitude: 37.4419, longitude: -122.1419)
mapView.setCenter(coordinate: coordinate, zoomLevel: 17.0, animated: true)To get the current zoom level
let level = mapView.zoomLevelhttp://troybrant.net/blog/2010/01/set-the-zoom-level-of-an-mkmapview/
