【中文标题】无法调试在 Xamarin.Forms 中制作的 IOS 应用程序【英文标题】：Cannot Debug IOS app made in Xamarin.Forms 【发布时间】：2021-11-12 16:14:24 【问题描述】：

这是我第一次使用 Xamarin.Forms 开发移动应用程序。我已经尝试了几天来解决这个问题，但我无法弄清楚。

基本上，我正在尝试在我的 iPhone 上调试应用程序，它成功构建并安装在手机上，但是当我运行应用程序时（根据调试器的要求），它只显示启动画面，然后它崩溃（超过 5 秒后）。检查调试控制台，我发现这个错误：

我正在使用 Visual Studio 16.11.3、Windows 10，并且我有一个有效的付费 Apple 开发者帐户。

【参考方案1】：

根据vscommunity中的这个question，好像是版本相关的问题，所以你可能需要升级你的visual studio再试一次。

【讨论】：

【参考方案2】：

当我在 ios 项目中删除 Xamarin.Forms.Visual.Material 时，它起作用了。

【讨论】：

你从哪里删除了这个程序集。我在我的 ios 项目中找不到那你的项目里没有
