Proper way to pass a class around SwiftUI views

I have a SwiftData class that I get with @Query private var items: [Item] in a SwiftUI view. Then I pass it to a sub view that passes it to other sub views. What is the best way to pass the class around. I need to be able to modify it, and its properties (structs and classes) in the sub views. Should I use @Binding, @Bindable, @ObservableObject or something else?

Here is an example of how to pass the items around to various subviews. In essence, use a let items: [Item] in the subviews that just display the info. Use a @Bindable var item: Item when you want to modify an item property. Use @Environment(\.modelContext) private var modelContext to add (or delete) an item to SwiftData, that will update your array items: [Item]. You cannot add or delete an item from the array items: [Item] directly (it is read only), you must use the context.

 @Model
 final class Item {
     var name: String
     
     init(name: String) {
         self.name = name
     }
 }
 
 @main
 struct TestApp: App {
     var body: some Scene {
         WindowGroup {
             ContentView()
         }
         .modelContainer(for: Item.self)
     }
 }

struct ContentView: View {
    @Query private var items: [Item]

    var body: some View {
        Layer1View(items: items)
    }
}

struct Layer1View: View {
    let items: [Item]
    
    var body: some View {
        Text("Layer1View items count: \(items.count)")
        Layer2View(items: items)
    }
}

struct Layer2View: View {
    @Environment(\.modelContext) private var modelContext
    let items: [Item]
    
    var body: some View {
        List(items) { item in
            EditorView(item: item)
        }
        Button("Add item") {
            let newItem = Item(name: "Mickey Mouse")
            modelContext.insert(newItem)
        }
    }
}

struct EditorView: View {
    @Bindable var item: Item
    
    var body: some View {
        TextField("", text: $item.name).border(.red)
    }
}
