How to show a Result of multiple choice's Question in other ViewController, when the function nextQuestion() in Struct (Xcode 13)

i just took the course Xcode from udemy and there is a project to create a QuizApp.

Everything works just fine, but i have idea to make a new View Control to give the result of the Quiz. But the code for Quiz is in a struct, so i can't use "instantiateViewController" in Struct to give the result to the ResultViewController.

Can anyone help me?

This is my code from QuestionViewController

import UIKit

class QuestionController: UIViewController {

@IBOutlet weak var questionLabel: UILabel!
@IBOutlet weak var progressBar: UIProgressView!

// Button and Score Outlet
@IBOutlet weak var answer1_label: UIButton!
@IBOutlet weak var answer2_Label: UIButton!
@IBOutlet weak var answer3_Label: UIButton!
@IBOutlet weak var scoreLabel: UILabel!

var quizBrain = QuizBrain()

override func viewDidLoad() {
    super.viewDidLoad()

    updateUI()
}


@IBAction func answerButtonPressed(_ sender: UIButton) {
    
    let userAnswer = sender.currentTitle!
            
    let userGotItRight = quizBrain.checkAnswer(userAnswer: userAnswer)
            
    if userGotItRight {
        sender.backgroundColor = UIColor.green
    } else {
        sender.backgroundColor = UIColor.red
    }
            
    quizBrain.nextQuestion()
    
            
    Timer.scheduledTimer(timeInterval: 0.2, target: self, selector: #selector(updateUI), userInfo: nil, repeats: false)
    
    

}

@objc func updateUI(){
    
    questionLabel.text = quizBrain.getQuestionText()
            
    //Need to fetch the answers and update the button titles using the setTitle method.
    let answerChoices = quizBrain.getAnswers()
    answer1_label.setTitle(answerChoices[0], for: .normal)
    answer2_Label.setTitle(answerChoices[1], for: .normal)
    answer3_Label.setTitle(answerChoices[2], for: .normal)
            
    progressBar.progress = quizBrain.getProgress()
    scoreLabel.text = "Score: \(quizBrain.getScore())"
    
    // Reset Button
    answer1_label.backgroundColor = UIColor.clear
    answer2_Label.backgroundColor = UIColor.clear
    answer3_Label.backgroundColor = UIColor.clear
    
        
}

}

This is the struct of QuizBrain

import Foundation

struct QuizBrain {

var questionNumber = 0
var score = 0


let quiz = [
    Question(q: "Which is the largest organ in the human body?", a: ["Heart", "Skin", "Large Intestine"], correctAnswer: "Skin"),
    Question(q: "Five dollars is worth how many nickels?", a: ["25", "50", "100"], correctAnswer: "100"),
    Question(q: "What do the letters in the GMT time zone stand for?", a: ["Global Meridian Time", "Greenwich Mean Time", "General Median Time"], correctAnswer: "Greenwich Mean Time"),
    Question(q: "What is the French word for 'hat'?", a: ["Chapeau", "Écharpe", "Bonnet"], correctAnswer: "Chapeau"),
    Question(q: "In past times, what would a gentleman keep in his fob pocket?", a: ["Notebook", "Handkerchief", "Watch"], correctAnswer: "Watch"),
    Question(q: "How would one say goodbye in Spanish?", a: ["Au Revoir", "Adiós", "Salir"], correctAnswer: "Adiós"),
    Question(q: "Which of these colours is NOT featured in the logo for Google?", a: ["Green", "Orange", "Blue"], correctAnswer: "Orange"),
    Question(q: "What alcoholic drink is made from molasses?", a: ["Rum", "Whisky", "Gin"], correctAnswer: "Rum"),
    Question(q: "What type of animal was Harambe?", a: ["Panda", "Gorilla", "Crocodile"], correctAnswer: "Gorilla"),
    Question(q: "Where is Tasmania located?", a: ["Indonesia", "Australia", "Scotland"], correctAnswer: "Australia")
]



func getQuestionText() -> String {
    return quiz[questionNumber].text
}

//Need a way of fetching the answer choices.
func getAnswers() -> [String] {
    return quiz[questionNumber].answers
}

func getProgress() -> Float {
    return Float(questionNumber) / Float(quiz.count)
}

mutating func getScore() -> Int {
    return score
}

mutating func nextQuestion() {
    if questionNumber + 1 < quiz.count {
        questionNumber += 1
    } else {
        questionNumber = 0
    }
}

mutating func checkAnswer(userAnswer: String) -> Bool {
    //Need to change answer to rightAnswer here.
    if userAnswer == quiz[questionNumber].rightAnswer {
        score += 1
        return true
    } else {
        return false
    }
  }
} 

i want to show the result in next Control View

And i think, i should change this function

mutating func nextQuestion() {
if questionNumber + 1 < quiz.count {
    questionNumber += 1
} else {
    questionNumber = 0
 }
}

but i don't have any clue, which code i should use to send the result to the ResultView

Can anyone help me?
