ios - 如何在Swift中构建React Native包？

coder 2024-01-28 原文

我想在swift中构建react本地ios photoeditor模块。
我只是使用react-native-create-library创建了一个新的库，并像这样修改了ios模块。
现在，我只想推一个简单的uiviewcontroller。
我跟踪了react native的Native Modules Guideline，但在启动应用程序时出错。
我附上了结构的截图，完整的代码和错误日志。

我真的不知道下面的错误是什么意思。
ld: symbol(s) not found for architecture arm64
另外，我怎样才能清除这种警告？
ld: warning: Could not find auto-linked library 'swiftUIKit'
有人能告诉我如何为react native编写swift ios库吗？我挣扎了几天，但没有运气。
我很感激你的帮助！谢谢。

最佳答案

您可以使用myhttps://github.com/iyegoroff/make-react-native-packagecli工具构建带有swift/kotlin/typescript的react本机包。
