React Native 0.66 iOS 在 AppDelegate RCTRootView 初始化时崩溃

Question

我正在尝试将我们的 RN 项目升级到 0.66（从 0.63）。当我在调试模式下构建项目时，由于 uncaught exception 'NSInvalidArgumentException', reason: '-[REAEventDispatcher setBridge:]: unrecognized selector sent to instance 0x600002f51cc0' 在初始化 AppDelegate.m 文件中的 RCTRootView （最后是整个文件）时，应用程序在启动时崩溃。

经过一番谷歌搜索，我发现unrecognized selector 位是因为某个对象上的某些函数未定义。错误在代码中被标记，大约是文件的一半。

我需要一些帮助来找出为什么这个功能不可用（或者还有什么问题）。据我所见，这些文件具有被调用函数的实现。我错过了任何进口吗？对 Swift 不太熟悉，只和 React Native 结合使用。

我没有做一个可重现的例子，但我希望其他人已经在移植到这个版本时遇到了这个问题。如果您需要更多信息，请询问。我还在相关文件下方附加了 podfile。

正如 jnpdx 指出的那样，我需要关注upgrade helper。事实证明，没有它，我错过了很多步骤。
