Xamarin.ios应用程序本机链接在更新VS 2019后失败 [英] Xamarin.ios app Native linking failed after updating VS 2019

问题描述

我正在使用PC上的Visual Studio 2019与2011年末的Macbook Pro配对开发xamarin.ios应用程序.今天，我不小心将Visual Studio更新为Version 16.5.4.将xamrin.ios更新为Version 13.16.0.13(b75deaf).之后，我将无法运行应用程序.视觉工作室告诉将Xcode更新为11.4，即11.3.为此，我需要将操作系统更新为catelina.，这是旧版Mac所没有的(同样我也不想升级).

I am developing xamarin.ios application using Visual studio 2019 on PC which paired with late 2011 Macbook Pro. Today I accidentally updated the Visual studio to Version 16.5.4. Which Updated the xamrin.ios to Version 13.16.0.13(b75deaf). After that I can't able to run application. The visual studio tells to update the Xcode to 11.4 Which is currenlty 11.3. In order to do that I need to update the OS to catelina.,which is not provided for the old mac(also I don't want to upgrade).

除此警告外，VS还引发了这些错误.

Apart from this warning these error also thrown by VS.

Native linking failed. Please review the build log and the user flags provided to gcc: -ObjC -lc++ -lsqlite3 -lz    



Native linking failed, undefined symbol: ___darwin_check_fd_set_overflow. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in.


linker command failed with exit code 1 (use -v to see invocation)   

如何在不更新Xcode的情况下解决此问题?是否可以降级VS?真的很感激任何帮助.

How can I solve this issue without updating the Xcode.Is downgrading of VS is possible? Any help is really apprecitated.

推荐答案

如果要获取Visual Studio或Xamarin.iOS的旧版本，则需要联系

If you want to get a older version of Visual-Studio or Xamarin.iOS, you need to contact to the support team to request the version you want.
