ios - 错误：global.nativeTraceBeginSection 不是函数

问题描述

我没有改变任何东西，但是突然我在我的 xproject 中遇到了这个错误，并且应用程序卡住了，当我通过我的 Xcode 进行模拟器工作时，我可以正常工作，但不能使用物理设备。完整的日志在这里：

我一直在努力寻找解决方案，但没有成功。此错误显示在我记录的 Xcode 上，而不是我的手机屏幕上

非常感谢你的帮助！！

解决方案

我遇到了同样的问题，因为我无意中启用了Start Systrace并且因为它是一个已知的反应本机问题......我收到了错误。

对我有用的只是禁用Start Systrace并重新启动项目。我该怎么做？

Command ⌘</kbd> + D

图像

按Disable Start Systrace，就是这样！
