XCode 6.3 MKPointAnnotation setCoordinate missing
As stated in the iOS 8.3 API Diffs in the MapKit module, the setCoordinate method was removed:
Removed MKAnnotation.setCoordinate(CLLocationCoordinate2D)
Fortunately, you must now use the simpler assignment syntax (which was already available in previous versions of Swift and the same could be done in Objective-C):
annotation.coordinate = location
