Possible to drive included views with new @FetchRequest property wrapper?

I want to drive SwiftUI views with the new

@

FetchRequest

property wrapper from the results of a fetch request. The first level, so just using a Text in the same struct where the fetch request is used, works fine and the view is updated if core data changes. If I integrate a

LandmarkRow(landmark: landmark)

this will not be updated anymore (but if copied the exact same code to the main view, it works)

Essentially I want to include views with the details as in the landmarks tutorial:

ForEach(userData.landmarks) { landmark in 
    if !self.userData.showFavoritesOnly || landmark.isFavorite { 
        NavigationLink(destination: LandmarkDetail(landmark: landmark)) { 
            LandmarkRow(landmark: landmark) 
        } 
    } 
}

Maybe there is a tutorial or some more information on how to use @FetchRequst and inherited views correctly?

Any idea on how to proceed?
