我试图找出我在 XCode 或我的 iPhone 中破坏了某些东西的地方。几天前一切正常 - 我按下运行 -> 构建成功 -> 一切都通过 wifi 工作（热重载）。
但是今天当我按下运行时 - 构建成功但它没有启动应用程序。重复运行后，一个应用程序正在启动，但没有连接到 Metro Builder。
我尝试在另一个办公室使用相同的组合。那里一切正常。
任何 Android 设备上的应用程序正在完美启动并连接到 Metro Builder。所有模拟器（包括通过 XCode）都运行良好。相同的无线网络。
XCode 中的输出：

我什至尝试只使用一个新项目进行测试 - react-native init，我遇到了同样的问题。
我应该在哪里检查？
