getGeoLocation(forPoint:completionHandler:)

Converts a position in the framework’s local coordinate system to latitude, longitude and altitude.

Declaration

func getGeoLocation(forPoint position: simd_float3, completionHandler: @escaping  @Sendable (CLLocationCoordinate2D, CLLocationDistance, (any Error)?) -> Void)
func geoLocation(forPoint position: simd_float3) async throws -> (CLLocationCoordinate2D, CLLocationDistance)

Parameters

  • position:

    Position in local coordinates to convert.

  • completionHandler:

    Code that control will execute when this function returns. The session runs this code on its delegate queue. The parameters are:

    coordinate

    Location coordinates (latitude, longitude).

    altitude

    The altitude.

    error

    The reason, if conversion fails.

Discussion

ARKit refers to its local coordinate space as “world” coordinate space, but this is different from geographic coordinates. For more information on ARKit’s coordinate space, see setWorldOrigin(relativeTransform:).

To succeed, this function requires an ARGeoTrackingConfiguration session with state equal to ARGeoTrackingStatus.State.localized.
