使用模拟器时Xcode控制打印Sending selectors failed with: Error Domain=NSCocoaErrorDomain Code=4099

 [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～

关闭打印：

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

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！！！！
