SwiftUI中NavigationSplitView导航状态持久化问题

问题现象 #

使用带侧边栏的NavigationSplitView，侧边栏通过NavigationLink跳转到包含NavigationStack、自有NavigationLinks、NavigationDestinations及导航路径的HomeView。尝试用@SceneStorage序列化保存路径，实现切换侧边栏时保留视图导航状态，但出现以下错误提示：

Note: Links search for destinations in any surrounding NavigationStack, then within the same column of a NavigationSplitView.
A NavigationLink is presenting a value of type “String” but there is no matching navigationDestination declaration visible from the location of the link. The link cannot be activated.
Note: Links search for destinations in any surrounding NavigationStack, then within the same column of a NavigationSplitView.

导航仅能正常工作一次，且仅在首次通过侧边栏导航前有效。

预期流程 #

通过侧边栏进入HomeView，从HomeView跳转到Test4NavView，切换侧边栏到其他视图后返回HomeView，仍停留在Test4NavView。

相关代码 #

MainView

var body: some View {
    NavigationSplitView(
        sidebar: { SidebarView() },
        detail: { HomeView()}
    )
}
}

侧边栏导航项（SidebarNavigationItem）

struct SidebarNavigationItem<Destination: View>: View {
    
    var option: String
    var icon: String
    var destination: Destination
    let arsColors = ARSColors.shared
    
    init(option: String, icon: String, destination: Destination) {
        self.option = option
        self.icon = icon
        self.destination = destination
    }
    
    var body: some View {
        NavigationLink(destination: destination) {
            Label {
                Text(option)
                    .foregroundColor(arsColors.primary)
            } icon: {
                Image(systemName: icon)
                    .foregroundColor(arsColors.highlight)
            }
        }
    }
}

HomeView（需保留导航状态的视图）

import SwiftUI

extension [String]: RawRepresentable {
    public init?(rawValue: String) {
        guard let data = rawValue.data(using: .utf8),
              let result = try? JSONDecoder().decode([String].self, from: data)
        else {
            return nil
        }
        self = result
    }
    
    public var rawValue: String {
        guard let data = try? JSONEncoder().encode(self),
            let result = String(data: data, encoding: .utf8)
        else {
            return "[]"
        }
        return result
    }
}

struct HomeView: View {
    
    @SceneStorage("navPath") var navPath: [String] = []
    
    var body: some View {
        NavigationStack(path: $navPath) {
            VStack {
                Spacer()
                
                HStack {
                    NavigationLink(value: navPath) {
                        WidgetView(widgetText: "Testnavigation")
                    }
                    
                    Spacer()
                    WidgetView(widgetText: "Wifget2")
                    Spacer()
                    WidgetView(widgetText: "Widget3")
                    Spacer()
                    WidgetView(widgetText: "Widget4")
                    Spacer()
                    WidgetView(widgetText: "Widget5")
                }
                .padding(.all)
            }
            .navigationTitle("Home")
            .navigationDestination(for: [String].self) {navPath in
                Test4NavView(navPath: navPath)
            }
        }
        .onAppear(){
            print(navPath)
        }
        .onDisappear() {
            print(navPath)
        }
    }
}

Test4NavView

struct Test4NavView: View {
    
    var navPath: [String]
    
    @SceneStorage("input1") private var input1: String = ""
    @SceneStorage("input2") private var input2: String = ""
    @SceneStorage("input3") private var input3: String = ""
    @SceneStorage("input4") private var input4: String = ""

    
    var body: some View {
        VStack(alignment: .center) {
            
            TextField("Input 1", text: $input1)
            TextField("Input 2", text: $input2)
            TextField("Input 3", text: $input3)
            TextField("Input 4", text: $input4)
        }
        .onAppear(){
            print(navPath)
        }
        .onDisappear() {
            print(navPath)
        }
    }
}
