How to embed WidgetKit extension into Xamarin.forms?

Question

I have an application created in swift and a widget using WidgetKit extension in SwiftUI. Now I want to embed the widget extension into xamarin. I came across a microsoft document on how to embed WidgetKit support in Xamarin, the link is as: https://docs.microsoft.com/en-us/xamarin/ios/platform/ios14/#embedded-widgetkit-support\ . Now when I am trying to embed it as given in the document, I am facing an error as, "ditto" exited with code 1. (MSB6006). I have gone through some references but still unable to resolve it.

P.S. I have added the screenshots if it may help you.

Hey @JuniorJiang-MSFT, thanks for the suggestion. I will look into it as well. But in my view it is probably not an issue because embedding WidgetKit extension in Xamarin is possible. And MSB6006 issue usually arises when signing issues are there. I would be glad to know if anyone has come across this and have been able to resolve it. Just correct me if I am wrong please. — Krits
Hi, I found that there is a feedback of this document. There is a same error code with yours: "ditto" exited with code 1, and finally the people has the same error solved this by referring this PR. You also could have a look at that to try. — Junior Jiang

Native extension:

Xamarin iOS:

In addition, you will see that extension and app also need to use the same App Groups.

Now the provisioning file will show:
