React Native：Xcode 中的未定义符号：_swift_stdlib_isStackAllocationSafe

Question

13.3.1将 Xcode 更新为React Native后出现错误。升级之前Xcode应用程序运行良好。另外，我没有更改任何代码。但我仍然收到错误。我不知道为什么更新后我收到此错误。

Error: Undefined symbol: _swift_stdlib_isStackAllocationSafe

react-native": "0.64.2"

为什么我会收到此错误？并且，我该如何解决这个错误？

你已经弄清楚这一点了吗？我怀疑 Launch Darkly RN SDK 已经过时了，因为他们仍在使用旧的状态管理形式。
