Xamarin iOS build error - Native linking failed (Link Framework SDKs Only)

The latest version of Visual-Studio use the latest version of Xamarin.iOS which may not work with the lower version of Xcode .

So use a lower Xamarin.iOS Version would solve this problem.

Cause : Latest visual studio requires latest Xcode (iOS 13.4 SDK shipped with Xcode 11.4)

To solve the issue install the latest Xcode or use a lower Xamarin.iOS Version

 if you are on a mac, you might be able to find the previous installer here:

~/Library/Caches/VisualStudio/[Replace with Visual Studio Version]/TempDownload

or, if you know the version of the previous version of ios, you can download it from here (change the version number to suite your needs:

https://dl.xamarin.com/MonoTouch/Mac/xamarin.ios-13.14.1.39.pkg.

Xamarin/xamarin-macios Releases, which contains every version

if you are on windows, this post might give you some clues on where to find the local cache instead: https://montemagno.com/cleanup-up-space-xamarin-dev-machine/
