SwiftUI dynamic List with #Binding controls - swiftui

Question

How do I build a dynamic list with #Binding-driven controls without having to reference the array manually? It seems obvious but using List or ForEach to iterate through the array give all sorts of strange errors.
struct OrderItem : Identifiable {
let id = UUID()
var label : String
var value : Bool = false
}
struct ContentView: View {
#State var items = [OrderItem(label: "Shirts"),
OrderItem(label: "Pants"),
OrderItem(label: "Socks")]
var body: some View {
NavigationView {
Form {
Section {
List {
Toggle(items[0].label, isOn: $items[0].value)
Toggle(items[1].label, isOn: $items[1].value)
Toggle(items[2].label, isOn: $items[2].value)
}
}
}.navigationBarTitle("Clothing")
}
}
}
This doesn't work:
...
Section {
List($items, id: \.id) { item in
Toggle(item.label, isOn: item.value)
}
}
...
Type '_' has no member 'id'
Nor does:
...
Section {
List($items) { item in
Toggle(item.label, isOn: item.value)
}
}
...
Generic parameter 'SelectionValue' could not be inferred

Answer 1

Try something like
...
Section {
List(items.indices) { index in
Toggle(self.items[index].label, isOn: self.$items[index].value)
}
}
...

Answer 2

While Maki's answer works (in some cases). It is not optimal and it's discouraged by Apple. Instead, they proposed the following solution during WWDC 2021:
Simply pass a binding to your collection into the list, using the
normal dollar sign operator, and SwiftUI will pass back a binding to
each individual element within the closure.
Like this:
struct ContentView: View {
#State var items = [OrderItem(label: "Shirts"),
OrderItem(label: "Pants"),
OrderItem(label: "Socks")]
var body: some View {
NavigationView {
Form {
Section {
List($items) { $item in
Toggle(item.label, isOn: $item.value)
}
}
}.navigationBarTitle("Clothing")
}
}
}
