NavigationWaypointArrivalObserver

public protocol NavigationWaypointArrivalObserver : Observer

An observer that receives navigation events related with visiting waypoints.

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

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

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

class NavigationWaypointArrivalObserverImpl: 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 register this observer using addWaypointArrivalObserver(_:).

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