Question

我正面临一个奇怪的情况，

更新Visual Studio 2019之后，我无法在iOS中运行该应用程序，当我尝试从链接到Mac的Windows计算机运行时会发生这种情况。但是，当我使用Visual Studio for Mac（而不是Windows）运行该应用程序时，该应用程序运行没有问题。

我查看了VS配置和Xcode的路径，并且它们是正确的（/Applications/Xcode.app)。Mac上的路径存在并且可以访问。

我尝试了以下解决方案，但是它不起作用：打开模拟器->单击顶部菜单模拟器->单击**重置内容和设置...。** 同样在Windows和Mac中，体系结构均为x86_64。

Windows计算机： Visual Studio 2019专业版16.3.7 Xamarin.iOS和Xamarin.Mac SDK-13.4.0.2（e37549b）

Mac： Visual Studio 2019 Enterprise for Mac版本8.3.5（内部版本13） Xcode 11.2（11B52） Xamarin.iOS和Xamarin.Mac SDK-13.4.0.2（e37549bc）

Windows上VS的输出：输出控制台：该应用已终止。启动失败。无法在“ iPhone 11 iOS 13.2”上启动应用程序“ AppName”。错误：错误HE0042：无法在设备“ iOS 13.2（17B84）-iPhone 11”上启动应用程序“ PackageName”：打开“ PackageName”的请求失败。。请查看日志以获取更多详细信息。该应用已终止。

构建输出：

Answer 1

我终于解决了。

Windows上的VS与CoreSimulator.Framework之间存在通信错误。

我运行以下命令从终端重新安装CoreSimulator.Framework：

sudo rm -Rf /Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/*
/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -runFirstLaunch

然后Xamarin.iOS项目的配置正在更改调试端口（新端口），在“执行模式”上的“ iOS运行选项”上配置为“默认无后台获取”。

希望此问题对其他人有帮助。
