title: no type or protocol named 'NFCVASReaderSessionDelegate' while building Xamarin.iOS
body: <p>I am struggling to build my Xamarin.IOS a project since the last two days but I am unable to build it. I am continuously getting the following error:</p>
  <p>no type or protocol named 'NFCVASReaderSessionDelegate' ProjectName.iOS C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets</p>
  <p>Can someone tell me what could be the reason and why I am not getting rid of that error?</p>
