A single route between a requested start and end point.
Declaration
class MKRouteOverview
An MKRoute object defines the geometry for the route — that is, it contains line segments associated with specific map coordinates. A route object may also include other information, such as the name of the route, its distance, and the expected travel time.
You don’t create instances of this class directly. When you use an MKDirections object to request directions from Apple, the returned MKDirections.Response object contains the possible routes.
