我不断看到很多操作系统日志，例如下面的
[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.}
我尝试添加OS_ACTIVITY_MODE env变量，但这会完全删除所有日志记录
OS_ACTIVITY_MODE = null
OS_ACTIVITY_MODE = disable
是否存在适用于Xcode 10.2的选项？
