maximumBearingSmoothingAngle
Controls how much the bearing can deviate from the location’s bearing, in degrees.

In case if set, the bearing property of CameraOptions during active guidance navigation won’t exactly reflect the bearing returned by the location, but will also be affected by the direction to the upcoming framed geometry, to maximize the viewable area.

Defaults to 20.0 degrees.

                    init(_:viewportDataSourceType:)

Initializer of NavigationViewportDataSource object.

Declaration

Swift

public required init(_ mapView: MapView, viewportDataSourceType: ViewportDataSourceType = .passive)

Parameters

`mapView`	Instance of `MapView`, which is going to be used for several operations, which includes (but not limited to) subscription to raw location updates via `LocationConsumer` (in case if `viewportDataSourceType` was set to `.raw`). `MapView` will be weakly stored by `NavigationViewportDataSource`.
`viewportDataSourceType`	Type of locations, which will be used to prepare `CameraOptions`.
