ios – The way to keep away from a line connection between start line and finish level on a map view to get printed picture with MKMapSnapshotter?

func saveMapViewAsImage(area: MKCoordinateRegion, dimension: CGSize) {
    let choices = MKMapSnapshotter.Choices()
    choices.area = area
    choices.dimension = dimension
    choices.mapType = .commonplace

    MKMapSnapshotter(choices: choices).begin { snapshot, error in
        guard let snapshot = snapshot else { return }
        
        let mapImage = snapshot.picture
        
        let finalImage = UIGraphicsImageRenderer(dimension: dimension).picture { _ in
            mapImage.draw(at: .zero)
                
            // get [CLLocationCoordinate2D]
            let coordinates = self.getTrackPointForPolyline()
            guard coordinates.depend > 1 else { return }
            
            // [CLLocationCoordinate2D] -> [CGPoint]
            let factors = coordinates.map { coordinate in
                snapshot.level(for: coordinate)
            }

            // draw traces
            let path = UIBezierPath()
            path.lineWidth = Ok.Map.routeLineWidth * 0.5
            path.lineCapStyle = .spherical
            path.lineJoinStyle = .spherical

            path.transfer(to: factors[0])
            for index in 1..<factors.depend {
                path.addLine(to: factors[index])
            }

            Ok.Map.routeLineColor.withAlphaComponent(0.75).setStroke()
            path.stroke()
        }

        // save as picture
        self.saveRenderedImageToDocumentDirectory(picture: finalImage)
    }
}
