iOS xcode升级10版本以后报错[Client] Sync

xcode升级10版本以后运行控制台会输出:

[Client] Synchronous remote object proxy returned error: 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.}

• 虽然出现这个错误但是程序可以正常运行，想要去掉这个输出信息需要在终端输入：

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