如何调试 "Failed to install" 消息？

Question

我目前正在尝试使用 Xamarin.forms 开发跨平台移动应用程序。作为此应用程序的一部分，我需要在我的 Xamarin.iOS 项目中包含一个第三方 .framework。我已成功创建 Xamarin.iOS 绑定库 .dll 并将其包含在我的项目中。我能够引用该库并在没有错误的情况下进行编译，但是当我尝试将应用程序部署到 iPhone 模拟器时，该应用程序将启动，然后崩溃并显示“安装失败”消息。

Error Message

如果我删除任何引用此 .dll 的代码行，应用程序将运行正常。

有没有人知道如何解决这个问题？

可能有用的信息：
我正在 Visual Studio 开发 Windows
Xamarin 版本：16.7.000.440
Xamarin.iOS版本：13.20.2.2
XCode版本：12.0.1
iOS版本：14.0

Answer 1

来自 apple document，错误意味着您链接了框架，但没有 ember 它。

The app crashes at launch, because the dynamic linker can’t locate the missing framework.

所以你需要做的是ember框架，这里是你可以参考的文档：
