Hi, guys. First time posting here.

I thought Day 25 project was very challenging but interesting, and you could make it in many different ways.

Here is my version. And I hope you can tell me your opinion about it.

import SwiftUI

struct ContentView: View {
    let moves = ["Rock", "Paper", "Scissors"]
    @State private var choice = Int.random(in: 0...2)
    @State private var winOr = Bool.random()
    @State private var userScore = 0

    @State private var showingFinish = false
    @State private var loopTimes = 0

    var body: some View {
        NavigationView {
            ZStack {
                VStack(spacing: 20) {
                    Text("Player's Score: \(userScore)")
                    Text("Computer's Move: ")
                    Text("You need to \(winOr == true ? "Win" : "Lose") against \(moves[choice])")

                    ForEach(0 ..< 3) {number in
                        Button(action: {
                            self.buttonTapped(number)
                        }) {
                            Text(moves[number])
                        }
                    }
                    Spacer()
                }
                .alert(isPresented: $showingFinish) {
                    Alert(title: Text("Good game!"), message:
                          Text("The game is over. Your final score is: \(userScore)"),
                          dismissButton: .default(Text("Play again!")) {
                            userScore = 0
                          })
                }
            }

            .navigationTitle("Brain Train Game")
        }
    }

    func buttonTapped(_ number: Int) {
        loopTimes += 1

        if winOr == true && winLogic(ai: moves[choice], player: moves[number]) == true {
            userScore += 1
        } else if winOr == false && winLogic(ai: moves[choice], player: moves[number]) == false {
            userScore += 1
        } else {
            userScore -= 1
        }
        reDo()

        if loopTimes >= 10 {
            loopTimes = 0
            showingFinish = true
        }
    }

    func winLogic(ai: String, player: String) -> Bool? {
        if ai == player {
            return nil
        } else if ai == "Rock" && player == "Scissors" {
            return false
        } else if ai == "Paper" && player == "Rock" {
            return false
        } else if ai == "Scissors" && player == "Paper" {
            return false
        } else {
            return true
        }
    }

    func reDo() {
        choice = Int.random(in: 0...2)
        winOr = Bool.random()
    }
}

If someone knows a better way to make logic for this game (the actual rock/paper/scissors part), please share :)
