How to call swiftdata .fetch inside the Init of a SwiftUI View?

I have a list of swiftdata objects I want to fetch and show in a swift UI list. My problem is the swiftdata object in my DB is not the object I directly want to use in my view. I want to map it to a different viewModel and use that which makes my life wayyy easier.

problem is every single example I see online of swift data, just uses the magic @Query operator to get their data, and then directly show it on the UI.

What's the best way for me to load the data on initialization but map it to a different type? I've tried this, but it just crashes.

init() {
     do {
            modelContainer = try ModelContainer(for: MY_DATA_CLASS.self)
       } catch {
             fatalError("Could not initialize ModelContainer")
        }

    let serverList = FetchDescriptor<MY_DATA_CLASS>(
        sortBy: [SortDescriptor(\.displayOrder)]
    )

    do {
        viewModels =  try modelContext.fetch(serverList).map {
            ViewModel(server: $0)
        }
    } catch {
        print(" WHAT THE HECKKK: " + error.localizedDescription)
    }

 }

NSFetchRequest could not locate an NSEntityDescription for entity name ....

any suggestions greatly appreciated. Using @query works fine so I know the rest of the DB is setup correctly.
