Below is the solution:

Rock, Paper, Scissor game to play with computer that will show the your score, computer score and draw score how many times.

create a view on the IOS Main.storyboard:

In a view controller file:

import UIKit
import GameplayKit

class RPSVC: UIViewController {
    //declare the variable
    var drawScoreInt : Int = 0
    var userScoreInt : Int = 0
    var computerScoreInt : Int = 0
    var choice : String! //choice string will have the choice
    let randomChoice = GKRandomDistribution(lowestValue: 0, highestValue: 2) //random number
    //create an button and label
    @IBOutlet weak var rockBtn: UIButton!
    @IBOutlet weak var paperBtn: UIButton!
    @IBOutlet weak var scissorsBtn: UIButton!
    @IBOutlet weak var computerChoice: UILabel!
    @IBOutlet weak var statusLabel: UILabel!
    @IBOutlet weak var userChoice: UILabel!
    @IBOutlet weak var userScore: UILabel!
    @IBOutlet weak var drawScore: UILabel!
    @IBOutlet weak var computerScore: UILabel!
  
  
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    //button press event of rock
    @IBAction func rockBtnPressed(_ sender: Any) {
        choice = "??"
        getResult()
    }
    //button press event of paper
    @IBAction func paperBtnPressed(_ sender: Any) {
        choice = "✋?"
        getResult()
    }
    //button press event of rock
    @IBAction func scissors(_ sender: Any) {
        choice = "✌?"
        getResult()
      
    }
    //find the result
    func getResult() {
        paperBtn.isHidden = true
        scissorsBtn.isHidden = true
        rockBtn.isHidden = true
        userChoice.isHidden = false
        userChoice.text = choice
        computerChoice.text = randomSign() //get the random selection
        statusLabel.text = calculateResult(user: choice, computer: computerChoice.text!) //call the function to calculate the result
        DispatchQueue.main.asyncAfter(deadline: .now() + 0.7, execute: {
            self.resetItems() //reset the all items
        })
    }
    //check for the which sgn has selected
    func randomSign() -> String { //return a String
        let sign = randomChoice.nextInt()
        if sign == 0 { // return rock sign
            let rock : String = "??"
            return rock
        } else if sign == 1 { //return paper
            let paper : String = "✋?"
            return paper
        } else { //return scissor
            let scissors : String = "✌?"
            return scissors
        }
    }
    //function will calculate the result and return as a string
    func calculateResult(user: String , computer: String) -> String {
        if user == computer { //check for the user selection and computer selection is same
            drawScoreInt = drawScoreInt + 1 //add the draw sore
            updateScores() //update score
            return "Draw!" //return the draw string
        } else if (user == "??" && computer == "✋?") || (user == "✋?" && computer == "✌?") || (user == "✌?" && computer == "??") { //check for the comuter win
            UIView.animate(withDuration: 0.2, animations: { () -> Void in //animation 2 secnds
                self.view.backgroundColor = #colorLiteral(red: 0.9058823529, green: 0.2980392157, blue: 0.2352941176, alpha: 1) //background color to red to 2 seconds
            })
            whiteLabels() //call the function
            computerScoreInt = computerScoreInt + 1 //add the computer sore
            updateScores()
            return "You Lose" //return the string
        } else {
            UIView.animate(withDuration: 0.2, animations: { () -> Void in
                self.view.backgroundColor = #colorLiteral(red: 0.1529411765, green: 0.6823529412, blue: 0.3764705882, alpha: 1) //background color to green to 2 seconds
            })
            whiteLabels() // call the function
            userScoreInt = userScoreInt + 1 //add the user sore
            updateScores()
            return "You win!" //return the string
        }
    }
  
    func whiteLabels() {
        UIView.animate(withDuration: 0.2, animations: { () -> Void in
            //set the all label text to white
            self.userScore.textColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
            self.computerScore.textColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
            self.drawScore.textColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
            self.statusLabel.textColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
        })
    }
  
    func resetItems() { //reset the items of the UIView
        UIView.animate(withDuration: 0.2, animations: { () -> Void in
            self.view.backgroundColor = #colorLiteral(red: 0.9960784314, green: 0.8039215686, blue: 0.2470588235, alpha: 1) //yellow
            self.statusLabel.textColor = #colorLiteral(red: 0.1706000417, green: 0.1706000417, blue: 0.1706000417, alpha: 1) //transparent
            self.userScore.textColor = #colorLiteral(red: 0.1706000417, green: 0.1706000417, blue: 0.1706000417, alpha: 1) //transparent
            self.computerScore.textColor = #colorLiteral(red: 0.1706000417, green: 0.1706000417, blue: 0.1706000417, alpha: 1) //transparent
            self.drawScore.textColor = #colorLiteral(red: 0.1706000417, green: 0.1706000417, blue: 0.1706000417, alpha: 1)//transparent
        })
        paperBtn.isHidden = false //hide the button
        scissorsBtn.isHidden = false //hide the button
        rockBtn.isHidden = false //hide the button
        userChoice.isHidden = true
        computerChoice.text = "?"
        statusLabel.text = "Rock , Paper , Scissors?"
    }
  
    func updateScores() { //display the score to the user, computer and draw score
        userScore.text = "You: \(Int(userScoreInt))"
        drawScore.text = "Draw: \(Int(drawScoreInt))"
        computerScore.text = "Computer: \(Int(computerScoreInt))"
    }
  
    override var prefersStatusBarHidden: Bool {
        return true
    }
}
