Route to Navigation points

The Navigation SDK for iOS offers enhanced ways to specify waypoints, providing more accurate routing and a better arrival experience, especially for destinations with multiple entrances or specific access points. You can route to precise locations using a navigationPointToken or by combining location coordinates with a Place ID for added context.

The destination highlighting feature will continue to be performed if applicable.

Background

Prior to v10.10, you could define a Waypoint using either location coordinates or a Place ID. While sometimes effective, routing solely to a latitude and longitude can sometimes lead to suboptimal drop-off or pick-up points, particularly for large venues, parks, or buildings with multiple entrances. The result might snap to the nearest road segment, which may not be the most convenient or correct access point.

The enhanced waypoint options address this by allowing you to provide more context.

Use a Navigation Point token

For the most precise routing to specific access points like entrances, loading docks, or designated pick-up areas, you can use a navigationPointToken .

This token is obtained by calling the Destinations method of the Geocoding API . It represents a specific, routable navigation point associated with a place.

To specify a Navigation Point token:

1. Obtain a navigationPointToken from the Destinations method of the Geocoding API response.

2. Specify that navigationPointToken when you create a GMSNavigationWaypoint .

Note:You cannot simultaneously specify a Navigation point token along with a location and PlaceID.

  // Create a waypoint using a navigation endpoint token 
 let 
  
 waypointTwo 
  
 = 
  
 GMSNavigationWaypoint 
 ( 
  
 navigationPointToken 
 : 
  
 "ChIJALijSXPhQkARHmIozCCbXsASEgkFVjYHGH6PgBFrbM7wl3.." 
  
 title 
 : 
  
 "Sydney Opera House" 
 ) 
 // Route to the waypoint 
 navigator 
 . 
 setDestinations 
 ([ 
 waypointTwo 
 ]) 
  
 { 
  
 [ 
 weak 
  
 self 
 ] 
  
 routeStatus 
  
 in 
  
 self 
 ?. 
 handleRouteCallback 
 ( 
 status 
 : 
  
 routeStatus 
 ) 
 } 
 

  GMSNavigationWaypoint 
  
 * 
 waypointTwo 
  
 = 
  
 [[ 
 GMSNavigationWaypoint 
  
 alloc 
 ] 
  
 initWithNavigationPointToek 
 : 
 @"sampleNavigationPointToken" 
 

Combine Place ID and Location

Starting with v10.10, you can provide both a Place ID and location coordinates when creating a waypoint. This method is useful when you want to specify a precise point (the location) while still providing the context of the overall place (the Place ID). This allows the Navigation SDK to provide a richer arrival experience by highlighting the destination building or showing nearby points of interest related to the Place ID.

  // Create a waypoint using both the latlng and placeID 
 let 
  
 waypoint 
  
 = 
  
 GMSNavigationWaypoint 
 ( 
  
 location 
 : 
  
 CLLocationCoordinate2DMake 
 ( 
 - 
 33.85657945261524 
 , 
  
 151.21535034203333 
 ), 
  
  
 placeID 
 : 
  
 "ChIJ3S-JXmauEmsRUcIaWtf4MzE" 
 , 
  
 title 
 : 
  
 "Sydney Opera House" 
 ) 
 // Route to the waypoint 
 navigator 
 . 
 setDestinations 
 ([ 
 waypoint 
 ]) 
  
 { 
  
 [ 
 weak 
  
 self 
 ] 
  
 routeStatus 
  
 in 
  
 self 
 ?. 
 handleRouteCallback 
 ( 
 status 
 : 
  
 routeStatus 
 ) 
 } 
 

  CLLocationCoordinate2D 
  
 location 
  
 = 
  
 CLLocationCoordinate2DMake 
 ( 
 47.67 
 , 
  
 -122.20 
 ); 
 GMSNavigationWaypoint 
  
 * 
 waypoint 
  
 = 
  
 [[ 
 GMSNavigationWaypoint 
  
 alloc 
 ] 
  
 initWithLocation 
 : 
 placeID 
 : 
 coordinate 
  
 title 
 : 
 @"waypoint from location and placeiD" 
 ]; 
 

Considerations:

When you provide both placeID and location :

• The route primarily targets the specified location .
• The placeId is used as context to enhance the arrival experience.
• Fallback:If the SDK determines that the provided placeId corresponds to a feature that is too far from the given location , the placeId will be ignored. In this scenario, routing will proceed to the location only, and the place-specific arrival experience enhancements won't be available.
