MKDirections object provides you with route-based directions data from Apple servers. You can use instances of this class to get travel-time information or driving or walking directions based on the data in an
MKDirections object that you provide. The directions object passes your request to the Apple servers and returns the requested information to a block that you provide.

- macOS 10.9+
- tvOS 9.2+
Each directions object handles a single request for directions, although you can cancel and restart that request as needed. You can create multiple instances of this class and process different route requests at the same time, but you should make requests only when you plan to present the corresponding route information to the user. Apps may receive a
loading error if too many requests have been made from the current device in too short a time period.
