React本机: xcode在设备上成功构建，但不连接到城域网构建器

Question

Native0.61

我想弄清楚我在XCode或iPhone中弄坏了什么东西。几天前，一切都很好--我按下了Run，->构建成功了，->和所有东西都通过wifi (热重装)工作。

但今天，当我按下，运行-构建是成功的，但它不是启动一个应用程序。经过多次运行，一个应用程序正在启动，但没有与地铁建设者连接。

我试着在另一间办公室用同样的密码。那里一切都很好。

android设备上的一个应用程序正在推出完美的应用程序，并与地铁建设者连接。所有模拟器(包括通过XCode)工作正常。同样的WiFi。

输出( XCode: )

我甚至试着用一个新的项目--react-原生init进行测试，在这里我也遇到了同样的问题。

我应该在哪里查一下？

转到XCode并检查构建日志。这可能是JS中的一些语法问题。
