Zoom to fit current location and annotation on map

mapkit, swift

Solution

`MKMapRectUnion` computes and returns a new rect, nothing more. You need to tell the mapView to set its visible area to that new rect:

myMapView.setVisibleMapRect(zoomRect, animated: true)

Problem

I am new to swift (iOS programming in general) and am trying to figure out how to zoom a map out to fit 2 points on the map. Currently I have ``` var zoomRect = MKMapRectNull; var myLocationPointRect = MKMapRectMake(myLocation.longitude, myLocation.latitude, 0, 0) var currentDestinationPointRect = MKMapRectMake(currentDestination.longitude, currentDestination.latitude, 0, 0) zoomRect = myLocationPointRect; zoomRect = MKMapRectUnion(zoomRect, currentDestinationPointRect); ``` Which does nothing. Do I have to apply `zoomRect` to the map somehow?
