【问题讨论】：

我已经能够在我的 iOS 项目中包含来自模拟器和设备的 firebase。我没有遇到他的问题

你能试试最新的 react-native 吗？我相信这是由github.com/facebook/react-native/commit/… 修复的，但我不确定是什么版本使它成为...

【参考方案1】：

只是日志中的一个想法：

 Websocket connecting to wss://<app-name>.firebaseio.com/.ws?v=5 

也许您需要配置 firebase 应用名称，还是无论如何都显示？

【讨论】：

我从日志中删除了实际名称

想得太明显了：p

【参考方案2】：

这是由于 react-native WebSocket polyfill 的一个错误，应该在最新的位中修复（https://github.com/facebook/react-native/commit/607527c0d4bf6d8197829f3523c4d937ac71ed07）。请尝试更新，看看问题是否消失！

【参考方案3】：

还要确保您已在 Firebase 数据库上启用公共读取访问权限。 Firebase Db setup
