未定义符号: Swift.UInt8的标称类型描述符

Question

我正试图在Mini上运行一个带有苹果M1 chipset.The项目的本地应用程序，该项目在基于英特尔的系统上运行良好，但在M1上却没有运行。当我构建时，我会遇到以下错误。

我怎样才能解决这个问题。我已经尝试过添加Swift文件和桥文件。但work.Please帮不了我

Xcode版本: 13.0，React本机版本: 0.64.2，iOS模拟器15，Mac : 11.4

对于那些仍有此问题的人，您可以尝试以下方法，因为它对我有用：

指向原始帖子的链接：https://dev.to/mngyuan/updating-react-native-projects-for-m1-mac-development-1mk4

我们将把arm64架构排除在构建之外。在“目标”下，选择您的项目“->构建设置->排除体系结构”，并添加用于调试和发布的任何IOS模拟器SDK : arm64。对你的Pods项目也做同样的事情。

如果您的项目由于某种原因设置了VALID_ARCHS，那么在这个阶段您也希望从项目(以及Pods项目)中删除该键。我们非常接近完成，但安装在您的豆荚中的Flipper版本可能还不够新，不足以包括M1 macs的修复程序。打开ios/Podfile并应用以下内容

• use_flipper!
• use_flipper!({ 'Flipper‘=> '0.75.0’}

更新你的口袋妖怪

cd ios/

如果您仍然有问题，可以重新安装所有的Pods

吊舱解体

吊舱更新

如果您执行了一个失败的构建，您可能需要像这样清除DerivedData

rm -rf ~/Library/Developer/Xcode/派生数据/

由于我运行的是reacti-native0.64，所以我还必须将它添加到我的pod文件中。
