尝试过iOS Build设置：

链接器行为
支持的体系结构
LLVM编译器
增量构建

还原Visual Studio Pro 2019是不得已的方法。任何想法表示赞赏。

Answer 1

将体系结构更改为仅ARM64，它将成功构建。

参见此处：https://github.com/xamarin/xamarin-macios/issues/6925

失败的原因是Xamarin.iOS 12.99（和13.0）附带的32位AOT编译器本身就是32位二进制文件，而32位二进制文件将无法在macOS 10.15 Catalina上执行。

希望这会有所帮助

Answer 2

发现了问题。在iPhone的iOS.csproj文件中对此设置-发布配置文件：

OnAppearing

在详细的构建日志中看到“ MONO_PATH不存在或权限错误”。

该项目现在已构建，我可以创建一个存档，并在Mac上查看IPA文件。
