Mapbox iOS SDK для навигации не работает с SwiftUI

Я получаю сообщение об ошибке:

Тип 'NavView' не соответствует протоколу 'UIViewRepresentable'

Вот мой код. Что мне делать? Спасибо. Использование SwiftUI 

struct NavView: UIViewRepresentable{

    func makeUIView(context: Context) -> NavigationViewController {
        var viewController: NavigationViewController

        // Define two waypoints to travel between
        let origin = Waypoint(coordinate: CLLocationCoordinate2D(latitude: 38.9131752, longitude: -77.0324047), name: "Mapbox")
        let destination = Waypoint(coordinate: CLLocationCoordinate2D(latitude: 38.8977, longitude: -77.0365), name: "White House")

        // Set options
        let options = NavigationRouteOptions(waypoints: [origin, destination])

        // Request a route using MapboxDirections.swift
        Directions.shared.calculate(options) { (waypoints, routes, error) in
            guard let route = routes?.first else { return }
            // Pass the generated route to the the NavigationViewController
            viewController = NavigationViewController(for: route)
            viewController.modalPresentationStyle = .fullScreen

        }
    return viewController
    }

    func updateUIView(_ uiView: NavigationViewController, context: Context) {

    }
}

Для этого случая следует использовать UIViewControllerRepresentable, как показано ниже 

struct NavView: UIViewControllerRepresentable {

    func makeUIViewController(context: Context) -> NavigationViewController {
        var viewController: NavigationViewController

        // Define two waypoints to travel between
        let origin = Waypoint(coordinate: CLLocationCoordinate2D(latitude: 38.9131752, longitude: -77.0324047), name: "Mapbox")
        let destination = Waypoint(coordinate: CLLocationCoordinate2D(latitude: 38.8977, longitude: -77.0365), name: "White House")

        // Set options
        let options = NavigationRouteOptions(waypoints: [origin, destination])

        // Request a route using MapboxDirections.swift
        Directions.shared.calculate(options) { (waypoints, routes, error) in
            guard let route = routes?.first else { return }
            // Pass the generated route to the the NavigationViewController
            viewController = NavigationViewController(for: route)
            viewController.modalPresentationStyle = .fullScreen

        }
        return viewController
    }

    func updateUIViewController(_ uiViewController: NavigationViewController, context: Context) {

    }
}
...
