I'm trying to create turn-by-turn directions, and I want to create a follow effect. To do that I want the map camera heading to be pointed towards the next coordinate on the map. How would I find the heading from the user location to the next coordinate in MapKit with Swift?

The best way to accomplish this would be to use the following MKMapCamera initializer:

Code Block convenience init(lookingAtCenter centerCoordinate: CLLocationCoordinate2D, 
		 fromEyeCoordinate eyeCoordinate: CLLocationCoordinate2D, 
		 eyeAltitude: CLLocationDistance)

passing in the next maneuver's location as centerCoordinate and the user's location as eyeCoordinate. Then set MKMapView.camera to the resulting MKMapCamera.
