iOS mapkit，运载式名称崩溃，[logMessageLogging] 6.1无法检索carrierName

Question

我在应用程序中添加了mapkit。我已经将Mkmapview连接到Iboutlet的ViewController，它在模拟器中运行良好，但它在我的设备中崩溃了

[logMessagelogging] 6.1无法检索carrierName。cterror：domain-2，code-5，errstr：((OS/kern(失败(。

我正在从cllocationmanager中获取用户的位置，并尝试在地图中添加注释。代码如下：

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let userLocation:CLLocation = locations[0] as CLLocation
    let coordinate = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude, longitude: userLocation.coordinate.longitude)
    MD_myCurrentLocation = coordinate
    setupLocationMarker(coordinate:coordinate)
    manager.stopUpdatingLocation()
}

func setUplocationmarker(坐标：cllocation coortion2d({

    iosMap.removeAnnotations(iosMap.annotations)
    let span = MKCoordinateSpanMake(0.01, 0.01)
    let region = MKCoordinateRegion(center: coordinate, span: span)
    iosMap.setRegion(region, animated: true)
    let annotation = MKPointAnnotation()
    annotation.coordinate = coordinate
    iosMap.addAnnotation(annotation)

}
