未定义符号：Swift.UInt8 的名义类型描述符

Question

我正在尝试在配备 Apple M1 芯片组的 Mac Mini 中运行 React Native 应用程序。该项目在基于 Intel 的系统上运行良好，但在 M1 上运行不佳。当我构建时，出现以下错误。

我该如何解决这个问题。我已经尝试添加 Swift 文件和桥接文件。但这不起作用。请帮助我

Xcode版本：13.0， 反应本机版本：0.64.2， iOS模拟器15， Mac 操作系统：11.4，

Answer 1

对于那些仍然遇到此问题的人，您可以尝试以下方法，因为它对我有用：

原帖链接：https://dev.to/mngyuan/updating-react-native-projects-for-m1-mac-development-1mk4

我们将从我们的构建中排除arm64架构。在“目标”下，选择您的项目 -> 构建设置 -> 排除的架构，然后为调试和发布添加任何 IOS 模拟器 SDK：arm64。对您的 Pods 项目执行相同的操作。

如果您的项目由于某种原因设置了 VALID_ARCHS，则在此阶段您还需要从项目（以及 Pods 项目）中删除该密钥。 我们已经非常接近完成了，但是您的 Pod 中安装的 Flipper 版本可能不够新，无法包含针对 M1 Mac 的修复。打开 ios/Podfile 并应用以下内容

• 使用_flipper！

• use_flipper!({ 'Flipper' => '0.75.0' })

并更新您的 Pod

cd ios/

如果仍有问题，可以选择重新安装所有 Pod

豆荚分解

pod更新

如果您执行的构建失败，您可能需要像这样清除 DerivedData

rm -rf ~/Library/Developer/Xcode/DerivedData/

自从运行react-native 0.64以来，我还必须将其添加到我的pod文件中

Answer 2

未定义符号：CoreGraphics.CGFloat 的标称类型描述符

未定义符号：CoreGraphics.CGFloat的类型元数据

未定义符号：CoreGraphics.CGFloat 的协议一致性描述符：CoreGraphics 中的 Swift.Comparable

升级到 Xcode 16 后遇到上述类似错误的用户可以按照以下解决方案：

1。转到构建阶段

• 在导航器中选择您的项目。
• 选择您的目标。
• 导航到“构建阶段”选项卡。

2。将库添加到“链接二进制与库”：

• 展开“链接二进制文件与库”部分。
• 单击 + 按钮添加新库。
• 在出现的对话框中搜索 libswiftCoreGraphics.tbd。
• 选择它并单击添加。

3.清理并重建项目：

• 转到产品 > 清理构建文件夹（Shift + Command + K）。
• 再次构建项目（Command + B）。
