请求“始终”位置授权时出现BSMachError

Question

As advised by Apple（如果我正确理解了这一点），那么我最初是在寻求WhenInUse授权以启用我的应用程序的基本位置支持（我在AppDelegate中这样做）并逐步升级权限只能在实际使用此功能的Always中设置为ViewController。

// AppDelegate.swift
class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {

var m_location_manager = CLLocationManager()

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    m_location_manager.delegate = self
    if CLLocationManager.authorizationStatus() != .authorizedWhenInUse {
        m_location_manager.requestWhenInUseAuthorization()
    }
}

// MyViewController
class MyViewController: UIViewController, CLLocationManagerDelegate, GMSMapViewDelegate {

var m_location_manager = CLLocationManager()
override func viewDidLoad() {
    super.viewDidLoad()
    m_location_manager.delegate = self
    if CLLocationManager.authorizationStatus() != .authorizedAlways {
        m_location_manager.requestAlwaysAuthorization()
    }
    m_location_manager.desiredAccuracy = kCLLocationAccuracyBest
    m_location_manager.startUpdatingLocation()
}

我的info.plist看起来像这样：

启动该应用程序时，确实的确询问我是否要授权WhenInUse位置服务，一切正常。但是，在MyView中运行时，尽管一切似乎都正常（没有崩溃，但一切似乎都正常），但在控制台中却出现了两个这样的错误：

2018-10-11 15:17:26.174617+0300 MyApp[1174:245307] [Common] _BSMachError: port cd03; (os/kern) invalid capability (0x14) "Unable to insert COPY_SEND"

请注意，提到的端口并不总是相同的（我见过d303、163603等）。
