                    init(turnAngle:turnDirection:id:routeOffset:maneuverPoint:drivingSide:combinedWithNext:previousSignificantRoad:nextSignificantRoad:routePath:intersectionName:signpost:)

Initializes the guidance instruction, specifying values for its fields.

Throws

An exception of the type TurnGuidanceInstructionError

Declaration

Swift

public init(
    turnAngle: Measurement<UnitAngle>,
    turnDirection: TurnDirection,
    id: UUID,
    routeOffset: Measurement<UnitLength>,
    maneuverPoint: CLLocationCoordinate2D,

    signpost: Signpost? = nil
) throws

Parameters

`id`	The ID of the instruction.
`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.
`combinedWithNext`	Indicates whether the instruction should be combined with the next one. This can be used to build messages like “Turn left and then turn right”.
`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`	A list of `RoutePoint`s 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.
`turnAngle`	Turn angle relative to the driving direction on the route, expressed in the range -180…180 degrees.
`turnDirection`	Classification of the relative angle of the turn.
