Using CoreData with List and Section in SwiftUI

I am attempting to show a segmented list for a CoreData fetchedResult:

struct ScanSummaryView: View {
    let scans: FetchRequest<Scan>

    init(showSentScans: Bool) {
        scans = FetchRequest<Scan>(entity: Scan.entity(), sortDescriptors: [
            NSSortDescriptor(keyPath: \Scan.category, ascending: true)
        ])
    }

    var body: some View {
        NavigationView {
            List {
                ForEach(scans.wrappedValue) { scan in
                    Section(header: Text(scan.scanCategory)) {
                        ForEach(scan) { individual in
                            Text(scan.scanTitle)
                        }
                    }
                }
            }
        }
    }
}

But I receive the error

Cannot convert value of type 'FetchedResults.Element' (aka 'Scan') to expected argument type 'Range'

I am trying to group by scan.scanCategory and then show all the resulting scans grouped together.

What am I doing wrong? Thanks...
