如何删除SwiftUI列表和NavigationBar之间的多余空格

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {
            List {
                Text("Item 1")
                Text("Item 2")
                Text("Item 3")
            }
            .listStyle(.plain) // 设置列表样式为 plain
            .navigationBarTitle("Title") // 设置导航栏标题
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
