How does one enable selections in SwiftUI's List

Question

I am trying to create a simple multiple selection List with SwiftUI. I am unable to make it work.

List takes a second argument which is a SelectionManager, so I tri

Rather than using edit mode, I’d just update the row on the basis of the model, and toggle a boolean in the model when the row is tapped as suggested by https://stackoverflow.com/a/57023746/1271826. Perhaps something like:

struct MultipleSelectionRow: View {
    var content: Binding

    var body: some View {
        Button(action: {
            self.content.value.isSelected.toggle()
        }) {
            HStack {
                Text(content.value.text)
                Spacer()
                Image(systemName: content.value.isSelected ? "checkmark.circle.fill" : "circle")
            }
        }
    }
}

Where

protocol SelectableRow {
    var text: String { get }
    var isSelected: Bool { get set }
}

Then you can do things like:

struct Person: Hashable, Identifiable, SelectableRow {
    let id = UUID().uuidString
    let text: String
    var isSelected: Bool = false
}

struct ContentView : View {
    @State var people: [Person] = [
        Person(text: "Mo"),
        Person(text: "Larry"),
        Person(text: "Curly")
    ]

    var body: some View {
        List {
            ForEach($people.identified(by: \.id)) { person in
                MultipleSelectionRow(content: person)
            }
        }
    }
}
