在SwiftUI的ForEach中以绑定和非绑定方式使用数组的单个成员,而不使用索引

很抱歉,因为我是SwiftUI的新手-

我有一个类(Meal),它包含另一个类的对象数组(Food)。我在这里试图实现的是能够添加食物并在列表中更新,然后能够通过点击来编辑单个食物。

我正在迭代食物列表,并使用每种食物来(1)创建一个导航链接,(2)简单地在列表中列出食物的名称。问题是我得到了错误 Initializer 'init(_:)' requires that 'Binding<String>' conform to 'StringProtocol' 当我试图以一种“无约束”的方式引用食物时。具体来说,在下面的代码中,它位于行 Text(food.name) .

            ForEach($meal.foods) { food in
                NavigationLink(destination: FoodView(food: food)) {
                    Text(food.name)
                }
            }

我知道我可以迭代索引列表( 我想 )但我认为这可能是不好的做法。我正在尝试找出在这种情况下的最佳实践是什么。提前感谢!

完整代码如下:

// MARK: Views
struct ContentView: View {
    @State private var day = Day()
    
    var body: some View {
        MealView(meal: $day.meals.first!)
    }
}

struct MealView: View {
    @Binding var meal: Meal
    
    var body: some View {
        NavigationStack {
            List {
                ForEach($meal.foods) { food in
                    NavigationLink(destination: FoodView(food: food)) {
                        Text(food.name)
                    }
                }
            }
        }
 
    }
}

struct FoodView: View {
    @Binding var food: Food
    
    var body: some View {
        VStack {
            TextField("Food", text: $food.name)
        }
    }
}

// MARK: Data
class Day {
    var meals: [Meal] = [Meal()]
}

@Observable
class Meal: Identifiable {
    var id: UUID = UUID()
    var foods: [Food] = [Food(name: "Pizza"), Food(name: "Pasta"), Food(name: "Steak")]
}

@Observable
class Food: Identifiable {
    var id: UUID = UUID()
    var name: String
    
    init(name: String) {
        self.name = name
    }
}
