ios – Utilizing bindings when flattening a hierarchical listing in Swift

I’ve the next code given as the reply from this earlier query I requested:

struct Folder: Identifiable {
    let id: UUID
    var objects: [Int]
    let kids: [Folder]
    
    init(objects: [Int], kids: [Folder]) {
        self.id = UUID()
        self.objects = objects
        self.kids = kids
    }
    
    var flatList: [Int] {
        var objects = objects
        objects.append(contentsOf: kids.flatMap { $0.flatList })
        return objects
    }
}

struct ContentView: View {
    
    @State var parentFolder: Folder = Folder(objects: [0, 1, 2, 3], kids: [
        Folder(items: [4, 5, 6, 7, 8], kids: [
            Folder(items: [9, 10, 11, 12], kids: [])
        ])
    ])
        
    var physique: some View {
        VStack {
            ForEach(parentFolder.flatList, id: .self) { merchandise in
                Textual content("(merchandise)")
            }
        }
    }
}

I wish to do extra although. As an alternative of accessing the flatList as a replica of the information in objects and the objects in every little one in kids, I might prefer to entry the objects as bindings. In different phrases, I need to have the ability to view the objects in the entire hierarchical construction as a listing, however I might like to have the ability to modify every merchandise within the listing as nicely.

I’ve tried modifying flatList in order that it returns [Binding<Food>] as an alternative, however I am unable to fairly get it to work. Ideally I might substitute the primary line of flatList with one thing like

var objects = objects.map { Binding(get: { $0 }, set: { ...? }) }

However I am unsure what to exchange ...? by.
