xcframework is just a bundle format for libraries. it allows a single bundler for both swift and objective-c libraries that support multiple platforms. Xamarin added support.
see this thread (its the only documentation):
https://github.com/xamarin/xamarin-macios/issues/10774
note: Xamarin IOS only supports Xcode 14, be sure not to upgrade to the current version 15. As Xamarin IOS support ends May 1, 2024, you should start your Maui migration.
