    Comment on it

    Hi all,

    Tic-Tac-Toe is simple game in which you will try to mark your sign in three blocks to make a row , column or diagonal.

     

    RULES FOR TIC-TAC-TOE

    1. The game is played on a grid that's 3 squares by 3 squares.

    2. You are X, your friend (or the computer in this case) is O. Players take turns putting their marks in empty squares.

    3. The first player to get 3 of her marks in a row (up, down, across, or diagonally) is the winner.

    4. When all 9 squares are full, the game is over. If no player has 3 marks in a row, the game ends in a tie.

     

    How to make this game in swift

    1. Make a User Interface .In storyboard , Make a UILabel to show player turn and 3x3 UIButton matrix and make there action in you swift viewcontroller class. For eg :- 

    2. In you UIViewController file , connect your button action like matrix [0] [0] to zeroZeroAction shown above.

    @IBOutlet weak var nextTurnLbl: UILabel!
        var nextTurn:String = "X"
        
        var array: [[Int]] = [[0,0,0],[0,0,0],[0,0,0]]
        
        override func viewDidLoad() {
            super.viewDidLoad()
            // Do any additional setup after loading the view, typically from a nib.
            nextTurnLbl.text = "Turn :" + nextTurn
        }
    
        override func didReceiveMemoryWarning() {
            super.didReceiveMemoryWarning()
            // Dispose of any resources that can be recreated.
        }
    
        @IBAction func zeroZero(sender: UIButton) {
            sender.setTitle(nextTurn, forState: UIControlState.Normal)
            changeTurn(0,y: 0)
        }
        @IBAction func zeroOne(sender: UIButton) {
            sender.setTitle(nextTurn, forState: UIControlState.Normal)
            changeTurn(0,y: 1)
        }
        @IBAction func zeroTwo(sender: UIButton) {
            sender.setTitle(nextTurn, forState: UIControlState.Normal)
            changeTurn(0,y: 2)
        }
        @IBAction func oneZero(sender: UIButton) {
            sender.setTitle(nextTurn, forState: UIControlState.Normal)
            changeTurn(1,y: 0)
        }
        @IBAction func oneOne(sender: UIButton) {
            sender.setTitle(nextTurn, forState: UIControlState.Normal)
            changeTurn(1,y: 1)
        }
        @IBAction func oneTwo(sender: UIButton) {

            changeTurn(2,y: 0)
        }
        @IBAction func twoOne(sender: UIButton) {
            sender.setTitle(nextTurn, forState: UIControlState.Normal)
            changeTurn(2,y: 1)
        }
        @IBAction func twoTwo(sender: UIButton) {
            sender.setTitle(nextTurn, forState: UIControlState.Normal)
            changeTurn(2,y: 2)

            print(array)
            winCheck()

                        break
                    }
                    if colWin == true && colCheck != 0 {
                        print("We have a winner")
                        alertShow(nextTurn == "X" ?"We have a winner 0":"We have a winner X")
                        break
                    }
                }
            }
            
            for (var aa = 1;aa<3;aa++){
                if (array[0][0] == aa && array[1][1] == aa && array[2][2] == aa){

                else if (array[0][2] == aa && array[1][1] == aa && array[2][0] == aa){

                    break
                }
            }
            var draw=true
            for (var colum = 0;colum<3;colum++){
                for (var row = 0;row<3;row++){
                    if array[colum][row] == 0{
                       draw = false
                    }
                }

            if draw == true {
                alertShow("Match is draw")
            }
            
        }
        
        func alertShow(mess:String){
            let msgAlert = UIAlertController(title: "Result", message: mess, preferredStyle: UIAlertControllerStyle.Alert)
            
            msgAlert.addAction(UIAlertAction(title: "Dismiss", style: .Default, handler: { (action: UIAlertAction!) in
                
            }))
            
            presentViewController(msgAlert, animated: true, completion: nil)
        }
        
    

    first remove all existing function and add these function to your viewcontroller file. Run the code and enjoy your game.
