使用MapKit遇到错误。 [无法检索CarrierName。]

Question

我收到此错误消息：

2017-01-02 15:29:07.886534 TimeStamp [665：191103] [LogMessageLogging] 6.1无法检索CarrierName。 CTError：domain-2，code-5，errStr：（（os / kern）失败）

我想我想让应用程序每隔一分钟将我的位置更新到服务器。

我还在plist上设置了这两个键：

Privacy - Location Always Usage Description
Privacy - Location When In Use Usage Description

并在“capibilities”中启用“后台模式”，“位置更新”

我用谷歌搜索，发现很多人在将Xcode更新为8.1后遇到了这个问题。并且只有在使用MapKit时才会出现此问题。我想知道如何解决它？我是新手。我希望有人可以帮我解决这个问题。非常感谢你。
