Sorry about the delay here!
We're rolling out the breadcrumbs feature to the various providers (we do have about 25 so it takes some time unfortunately). I'll check in with the team members who manage our Xamarin SDK to see what the time frame looks like for it.
If you are using Raygun Pulse for Xamarin, it will record the views and network calls that are made, but won't appear as the 'breadcrumb' list. You can see the docs here: https://raygun.com/docs/pulse-for-mobile/xamarin-for-ios-pulse
