objective-c - 在 Unity iOS 中使用 swift 静态库

Question

我一直在尝试将我的 Unity 游戏与我在 Github 上找到的 iOS 静态库集成。该库在 Swift 中，但是，我分叉了该库，并提供了从 C# 代码进行调用所需的 Objective-C 绑定。

我的静态库在产品选项卡下的 xCode 项目中可用。为了在 Unity 中使用它，我将生成的库从“Reveal in file explorer”下的可用目录复制粘贴到 Unity。我把我的库放在插件目录中。

当我通过 Unity 解决方案生成的 iOS 模拟器上运行我的游戏时，我收到一个错误：

为了逐步验证 Unity 支持，我创建了一个 Objective-c 静态库 - Untiy 能够调用库并且我没有收到错误。之后，我向我的 Objective-C 库添加了 swift 支持，然后我再次遇到了平面命名空间的问题：

我一直在尝试设置不同的 xCode 标志，例如“始终嵌入 Swift 标准库”或“启用模块”，但仍然无法在 iOS 模拟器上运行我的游戏。

任何提示都非常感谢。
