去掉Xcode中错误提示：[Client] Synchronous remote object proxy returned error
Mac升级了系统，升级了Xcode后，每次运行项目都会有许多报错提示，debug窗口出现密密麻麻的错误日志，看着心烦头疼，我们尝试修改掉这些错误日志。
错误日志：
[Client]Synchronousremoteobjectproxy returned error:ErrorDomain=NSCocoaErrorDomainCode=4099"The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated."UserInfo={NSDebugDescription=Theconnection to service named com.apple.commcenter.coretelephony.xpc was invalidated.}
解决方案：
原因是模拟器的默认设置了开启子系统com.apple.CoreTelephony的日志记录，在终端运行指令关闭它就OK了。
xcrun simctl spawn booted log config --mode"level:off"--subsystem com.apple.CoreTelephony
仅做笔记 ~
