嵌入式导航链接

我正在尝试开发一个应用程序以进行一些认知测试

打开应用程序时，会出现带有NavigationLink {}的NavigationView {}

到目前为止正常链接之一 NavigationLink(destination: IntermediateCoreView()) { Text("Go to tests") }

带您进入测试的“预筛选”，您可以从中链接到“测试”的自身。从IntermediateCoreView.swift您可以 NavigationLink(destination: ContentView()) { Text("+ new test") }

哪个可行，您可以参加考试。在测试结束（经过X秒）后，它会显示一条警报，提示用户时间已用完，并将其带回Intermediate CoreView

当IntermediateCoreView导航视图中的“后退”按钮返回到“测试”视图时，这就是错误的地方。不回到初始视图

我知道这是“预期的行为”，测试已从发送到的屏幕返回。有没有办法覆盖这个？

要添加一个最小的示例-.app文件：

import SwiftUI

@main
struct minRep2App: App {
    var body: some Scene {
        WindowGroup {
            initialView()
        }
    }
}

然后是初始视图控制器：

import SwiftUI

struct initialView: View {
    var body: some View {
        NavigationView{
            List{
                NavigationLink(destination: ContentView()) {
                       Text("Go to CoRe tests")
                   }
            }
        }
      
    }
}
struct initialView_Previews: PreviewProvider {
    static var previews: some View {
        initialView()
    }
}

最后是测试演示

import SwiftUI

struct ContentView: View {
    @State private var timeRemaining = 50.00
    @State private var showingAlert = false
    @State var showIntermediate: Bool = false
    let timer = Timer.publish(every: 0.1, on: .main, in: .common).autoconnect()
    var body: some View {
        NavigationLink(destination: initialView(), isActive: self.$showIntermediate)
        {
            EmptyView()
        }
        Text("Test goes here")
            .padding()
        HStack{
            //  Text("Score: \(score)")
            Text("Time: \(timeRemaining)")
        }.padding(.bottom, 10)
        .onReceive(timer) { time in
            if self.timeRemaining > 0.1 {
                self.timeRemaining -= 1
            }
            if  self.timeRemaining == 0.0 {
                self.showingAlert = true
                self.timer.upstream.connect().cancel()
            }
        }
        .alert(isPresented: $showingAlert){
            Alert(title: Text("Warning"), message: Text("Sorry your time is up!"), dismissButton: .default(Text("OK"), action: {
                self.showIntermediate = true
            })
            )
        }
    }
}
struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
