NavigationWaypointArrivalObserver

public protocol NavigationWaypointArrivalObserver : Observer

Declares an observer that can receive navigation events related with visiting waypoints.

The waypoint arrival state changes are detected by the ArrivalDetectionEngine. Different observer methods are called depending on what state has been detected by the ArrivalDetectionEngine:

• didArriveAtWaypoint(waypoint:on:) is received when the ArrivalDetectionEngine detects an arrival at a waypoint.
• didDepartFromWaypoint(waypoint:on:) is received when the ArrivalDetectionEngine detects a departure from a waypoint.

To be notified about the waypoint arrival events while navigating, first implement the NavigationWaypointArrivalObserver protocol:

class CustomNavigationWaypointArrivalObserver: NavigationWaypointArrivalObserver {
    func didArriveAtWaypoint(waypoint: RouteStop, on route: Route) {
        // Add code here that handles an arrival at a waypoint.
    }

    func didDepartFromWaypoint(waypoint: RouteStop, on route: Route) {
        // Add code here that handles a departure from a waypoint.
    }
}

Then add this observer using addWaypointArrivalObserver(_:).

To stop receiving these events, remove the observer using removeWaypointArrivalObserver(_:).
