Showing a selection in a SwiftUI List from an observable object (not working atm!)

list-selection.swift

class Context: ObservableObject {

    init(selectedIngredients: Set<Ingredient>, ingredients: [Ingredient]) {
        self.selectedIngredients = selectedIngredients
        self.ingredients = ingredients
    }
        
    @Published var selectedIngredients: Set<Ingredient>
    let ingredients: [Ingredient]
}

struct Chooser : View {
    
    @ObservedObject var context: Context
    
    var body: some View {
        List(context.ingredients, id: \.self, selection: $context.selectedIngredients) { ingredient in
            Text(ingredient.name)
        }
        .environment(\.editMode, .constant(.active))
    }
}
