如何在MAPBOX iOS中将标记从一个位置动画移动到另一个位置？

import Mapbox

class ViewController: UIViewController, MGLMapViewDelegate {
    var mapView: MGLMapView!
    var marker: MGLPointAnnotation!
    var markerView: MGLAnnotationView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建地图视图
        mapView = MGLMapView(frame: view.bounds)
        mapView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        mapView.delegate = self
        view.addSubview(mapView)
        
        // 创建标记对象
        marker = MGLPointAnnotation()
        marker.coordinate = CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194)
        mapView.addAnnotation(marker)
        
        // 创建标记视图
        markerView = MGLAnnotationView(reuseIdentifier: "marker", size: CGSize(width: 50, height: 50))
        markerView.backgroundColor = .red
        markerView.layer.cornerRadius = markerView.frame.width / 2
        markerView.clipsToBounds = true
        
        // 将标记视图添加到标记对象上
        markerView.annotation = marker
        mapView.addSubview(markerView)
        
        // 创建动画对象
        let animation = CABasicAnimation(keyPath: "position")
        animation.fromValue = NSValue(mgl_coordinate: marker.coordinate)
        animation.toValue = NSValue(mgl_coordinate: CLLocationCoordinate2D(latitude: 40.7128, longitude: -74.0060))
        animation.duration = 2.0
        animation.timingFunction = CAMediaTimingFunction(name: .easeInEaseOut)
        
        // 将动画对象添加到标记视图的layer上
        markerView.layer.add(animation, forKey: "position")
        
        // 更新标记的位置信息
        marker.coordinate = CLLocationCoordinate2D(latitude: 40.7128, longitude: -74.0060)
    }
    
    // MARK: - MGLMapViewDelegate
    
    func mapView(_ mapView: MGLMapView, viewFor annotation: MGLAnnotation) -> MGLAnnotationView? {
        return nil
    }
}
