iOS [Client] Updating selectors

Xcode运行代码时打印的log：[Client] Sending selectors failed with: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated." UserInfo={NSDebugDescription=The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated.}

出现原因：大多数情况都是你开启了全局代理（科学上网），而去访问局域网资源～

解决方法：请关闭你的全局代理（科学上网）， 如果你在局域网的情况下！！！！

在终端直接运行下面这行：

xcrun simctl spawn booted log config --mode "level:off" --subsystem com.apple.CoreTelephony
