SWIFTUI -如何在测验应用程序中保持分数，并在不同的视图上显示问题？

struct Question {
    let text: String
    let answer: String
}

struct QuizView: View {
    @State private var currentQuestionIndex = 0
    @State private var score = 0

    let questions = [
        Question(text: "问题1", answer: "答案1"),
        Question(text: "问题2", answer: "答案2"),
        Question(text: "问题3", answer: "答案3")
    ]

    var body: some View {
        VStack {
            Text("问题：\(questions[currentQuestionIndex].text)")
                .font(.title)
                .padding()

            TextField("请输入答案", text: $answer)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()

            Button("提交答案") {
                checkAnswer()
            }
            .padding()

            Text("得分：\(score)")
                .font(.title)
                .padding()
        }
    }

    func checkAnswer() {
        let currentQuestion = questions[currentQuestionIndex]
        if answer == currentQuestion.answer {
            score += 1
        }

        if currentQuestionIndex < questions.count - 1 {
            currentQuestionIndex += 1
        } else {
            // 显示测验结束的提示或跳转到下一个视图
        }
    }
}

    var body: some Scene {
        WindowGroup {
