我正在尝试创建一个分组的简单动态列表。（SwiftUI iOS13 Xcode11 beta 2）

一个简单的静态示例为：

struct StaticListView : View {
    var body: some View {
        List {
            Section(header: Text("Numbers"), footer: Text("...footer...")) {
                Text("1")
                Text("2")
                Text("3")
            }
            Section(header: Text("Letters"), footer: Text("...footer...")) {
                Text("a")
                Text("b")
                Text("c")
            }
        }
    }
}

如预期的那样，这将显示一个带有节标题和页脚的漂亮列表

但是，当我尝试从这样的动态列表中执行此操作时：

struct TestData: Identifiable {
    var id = UUID()
    var title: String
    var items: [String]
}

struct ListView : View {
    let mygroups = [
        TestData(title: "Numbers", items: ["1","2","3"]),
        TestData(title: "Letters", items: ["A","B","C"]),
        TestData(title: "Symbols", items: ["€","%","&"])
    ]
    var body: …
