Swift: How a Button Can Perform a Sequence

How can a button unhid textfields each time its pressed and then after 4 times of being pressed the button becomes inactive? Here is my code so far. Thanks in advance!

import UIKit

class AddNewGameViewController: UIViewController {

    @IBOutlet weak var Player1: UITextField!
    @IBOutlet weak var Player2: UITextField!
    @IBOutlet weak var Player3: UITextField!
    @IBOutlet weak var Player4: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.


        Player1.hidden = true
        Player2.hidden = true
        Player3.hidden = true
        Player4.hidden = true



    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func addPlayer(sender: UIButton) {
        sender.enabled = false

        Player1.hidden = false
        Player2.hidden = false
        Player3.hidden = false
        Player4.hidden = false


    }

change your @IBOutlets to a @IBOutlet Collectionlike this :

@IBOutlet var players: [UITextField]!

then connect each textfield to it Player1->Player2-> Player3->Player4

finally in the btn action :

for textField in players {

    if textField.hidden {
        textField.hidden = false
        if textField == players.last {
            sender.enabled = false
        }
        break
    }

}

update

you can hide all them with players.forEach {$0.hidden = true} in viewDidload or hide them in xib/storyboard.
