Ios 通过SwiftUI中的多个视图绑定数组

我被这个问题困住了。我有一个从@Binding数组构建列表的结构

struct AppleList: View {

    @Binding var apples: [Apple]

    var body: some View {
        NavigationView {
            List {
                ForEach(apples) { apple  in
                    NavigationLink(destination: AppleDetail(apple: $apple)) {
                        AppleRow(apple: apple)
                    }
                }
            }
        }
    }
}

AppleDetail有一个编辑按钮，可在AppleSummary和AppleEditor之间切换，因此在此将修改apple

struct AppleDetail: View {

    @Binding var apple: Apple

    var body: some View {
        ...
    }
}

AppleRow不需要修改apple

struct AppleRow: View {

    var apple: Apple

    var body: some View {
        ...
    }
}

问题在于ForEach循环：如何从元素的绑定数组中生成一个绑定元素，这些元素在被修改时会将修改发送给AppleList的父元素？

解决方案非常简单：

ForEach(apples.indices) { idx in
    NavigationLink(destination: AppleDetail(transaction: self.$apples[idx])) {
        AppleRow(transaction: apples[idx])
    }
}

ForEach(apples.indices) { idx in
    NavigationLink(destination: AppleDetail(transaction: self.$apples[idx])) {
        AppleRow(transaction: apples[idx])
    }
}
