CLLocationManager的失败捕获

Question

我想在代理中观察到 CLError.Code.network.错误。所以测试：iphone不插电话卡，也不连网，在室内，但仍然拿不到这个错误。

测试结果：断开wifi的情况下，手机既不触发成功也不触发失败，开始会等待4，5分钟。然后触发了成功，精度200。然后开始连续不停的触发成功，经纬度不太一样，但精度都是200 。

预期 我预期的是触发network错误才对啊，哪位兄弟了解苹果的定位？

代码如下：
`

class cl_ViewController : UIViewController,CLLocationManagerDelegate {

     
     let cl = CLLocationManager()
     
    override func viewDidLoad() {
        super.viewDidLoad()
        cl.delegate = self
        cl.requestAlwaysAuthorization()
        cl.startUpdatingLocation()
    }
    
    //成功
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    
        let location = locations[0] as CLLocation
    
        var coo = "\(location.coordinate.longitude)   accuracy:\(location.horizontalAccuracy)"   

        toast(msg: coo)
    }
    //失败
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error){
        var msg = ""

        switch (error as NSError).code {
        case CLError.Code.denied.rawValue:
            msg = ("拒绝")
        case CLError.Code.network.rawValue:
            msg = ("断网")
        case CLError.Code.locationUnknown.rawValue:
            msg = ("内部失败")
        default:
            msg = ( "未知错误")
        }
        toast(msg: msg)
    }

｝
