Binding in a ForEach in SwiftUI

Question

I use a FetchRequest to fill the elements. Then I'm using a list and want to display some kind of todo elements where you see which one is checked and which one not. Therefor I created a CheckBoxView.

My problem now is, that I need to pass a binding to the view. But how to do that in the ForEach? If I have a single binding its easy for me, I just generate a @State and it works. How to do it here?

List {
    ForEach(elements, id: \.self) { item in
        CheckBoxView(checked: item.checked)
    }
}

Here is the view:

struct CheckBoxView: View {
    @Binding var checked: Bool
    ....
}

Answer 1

Assuming your elements is state of items array, it can be

List {
    ForEach(elements.indices, id: \.self) { i in
        CheckBoxView(checked: $elements[i].checked)
    }
}
