Example of using SectionedFetchQuery

WorkHistoryView.swift

struct WorkHistoryView: View {
    @SectionedFetchRequest<String, WorkHistoryEntry>(
        sectionIdentifier: \.createdAtDate,
        sortDescriptors: [SortDescriptor(\.createdAt, order: .reverse)]
    )
    private var historyEntrySections: SectionedFetchResults<String, WorkHistoryEntry>
    
    var body: some View {  
        List {
            ForEach(historyEntrySections) { historyEntrySection in
                Section(header: Text(historyEntrySection.id)) {
                    ForEach(historyEntrySection) { historyEntry in
                        WorkHistoryEntryView(historyEntry: historyEntry)
                    }
                }.headerProminence(.increased)
            }
        }.navigationTitle("history_title")
    }
    
}

extension WorkHistoryEntry {
    @objc
    var createdAtDate: String {
        let formatter = DateFormatter()
        formatter.dateStyle = .long
        formatter.doesRelativeDateFormatting = true
        
        return formatter.string(from: self.createdAt!)
    }
}
