如何在TabView SwiftUI中保存视图的列表状态

import SwiftUI
import Combine

class ListState: ObservableObject {
    @Published var selectedTab: Int = 0
    @Published var listData: [String] = []
}

struct ContentView: View {
    @EnvironmentObject var listState: ListState
    
    var body: some View {
        TabView(selection: $listState.selectedTab) {
            // 第一个Tab的视图
            FirstTabView()
                .tabItem {
                    Image(systemName: "1.circle")
                    Text("Tab 1")
                }
                .tag(0)
            
            // 第二个Tab的视图
            SecondTabView()
                .tabItem {
                    Image(systemName: "2.circle")
                    Text("Tab 2")
                }
                .tag(1)
        }
        .environmentObject(listState)
    }
}

struct FirstTabView: View {
    @EnvironmentObject var listState: ListState
    
    var body: some View {
        NavigationView {
            List(listState.listData, id: \.self) { item in
                Text(item)
            }
            .navigationBarTitle("First Tab")
            .onAppear {
                // 加载数据并更新列表
                listState.listData = ["Item 1", "Item 2", "Item 3"]
            }
        }
    }
}
