    override func viewDidAppear(_: Bool) {
        mapView.delegate = self
        addOverlays()
    }

    func mapView(_: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
        if let lineOverlay = overlay as? LineOverlay {
            return MapLineOverlayRenderer(lineOverlay)
        }
        return MKOverlayRenderer(overlay: overlay)
    }

    private func addOverlays() {
		let pointA = CLLocationCoordinate2DMake(41.375024, 2.149118) // Plaça d'Espanya, Barcelona
		let pointB = CLLocationCoordinate2DMake(41.380994, 2.185771) // Plaça Pau Vila, 1, Barcelona
        mapView.addOverlay(LineOverlay(origin: pointA, destination: pointB))
        let arc = ArcOverlay(origin: pointA, destination: pointB,
                             style: LineOverlayStyle(strokeColor: .systemTeal, lineWidth: 4, alpha: 1))
        arc.radiusMultiplier = 0.5
        mapView.addOverlay(arc)
    }
}

Question (Draggable Point at End of Line)

Hello! I need to have one end of the curved line be stationary that does not move then the other end be draggable by the user while keeping the curved line. What's the best way to do this? Thanks!
