    This is a Public Preview API. It may be changed or removed at any time.

    Declaration

    Swift

    turnAngle: Measurement<UnitAngle>,
    exitNumber: Int?,
    quantizedTurnAngle: QuantizedTurnAngle,

) throws

    Parameters

    turnAngle

    Turn angle relative to the driving direction on the route, in the range -180...180 degrees.
    exitNumber

    Exit number where the driver should leave the roundabout, counted from the entry point to the roundabout. If the route starts on the roundabout, counting starts from the departure point.
    quantizedTurnAngle

    Classification of the turn angle relative to the driving direction on the entry road to the roundabout.
    routeOffset

    The distance from the start of the route to the instruction point.
    maneuverPoint

    Location of the maneuver expressed as CLLocationCoordinate2D.
    drivingSide

    Indicates left-hand vs. right-hand side driving at the point of the maneuver.
    combineWithNext

    Indicates if the instruction should be combined with the next one. This can be used to build messages like “Turn left and then turn right”.
    announcements

    Fine-grained Announcements for the Instruction.
    previousSignificantRoad

    Information about the road the driver will be on immediately before starting the maneuver, if available for this instruction.
    nextSignificantRoad

    Information about the road the driver will be on immediately after completing the maneuver.
    routePath

    An array of RoutePoints that represents a route path.
    intersectionName

    Name of the intersection at the maneuver point, if present for this instruction.
    signpost

    Signpost information, if present for this instruction.
    landmark

    Landmark information, if present in this instruction.
    sideStreetOffset

    Distance to the maneuver point from the intermediate side street, if any.
    trafficLightOffset

    Distance to the maneuver point from the preceding traffic light, if any.
    id

    The ID of the instruction.

Public

  • id

    The ID of the instruction.

    Declaration

    Swift

    public let id: UUID

  • The distance from the start of the route to the instruction point.

    Declaration

    Swift

    public let routeOffset: Measurement<UnitLength>

  • Location of the maneuver expressed as CLLocationCoordinate2D.

    Declaration

    Swift

    public let maneuverPoint: CLLocationCoordinate2D

  • Indicates left-hand vs. right-hand side driving at the point of the maneuver.

    Declaration

    Swift

    public let drivingSide: DrivingSide

  • Indicates whether it is possible to combine the instruction with the next one. This can be used to build messages like “Turn left and then turn right”.

    Declaration

public let combineWithNext: Bool

  • Fine-grained Announcements for the Instruction.

    Declaration
