首先，您应该标记数组，就State好像您要更改视图内的数据一样，或者不理会它，但我选择State演示：

@State var fakeData = ["Array A", "Array B", "Array C", "Array D"]

然后只用一行代码从中列出一个列表：

List(fakeData, id:\.self) { Text($0) }

包起来：

struct ContentView: View {

    @State var fakeData = ["Array A", "Array B", "Array C", "Array D"]

    var body: some View {
        List(fakeData, id:\.self) { Text($0) }
    }
}
