React-Native 应用程序在 iOS 上挂起，但在 Android 上运行正常

Question

我有一个使用 React-Native 0.62.3 的应用程序，它不能在 iOS 上运行。它启动，从 Metro 接收捆绑包，除了不断显示启动画面外什么也不做。这是运行日志：

我曾尝试在 Google 上搜索 nw_socket_handle_socket_event [C6.1:1] Socket SO_ERROR [61: Connection refused]，但对我而言，似乎所有结果都与这条线循环有关，但就我而言，它只出现了 2 次。

最后一个日志字符串是来自应用程序的 console.log()，所以我猜它有点尝试工作，我不知道..

如果你能告诉我可能出了什么问题，我会非常高兴，因为我已经没有办法解决它了

xcode v12.0.1 ios 14 模拟器

如果我能提供任何对你有用的信息，请告诉我

Answer 1

我遇到了这个问题，发现这是因为我的 iPhone 和运行 XCode 的 Mac 位于不同的 WiFi 网络上。验证两台设备是否在同一网络上。
