Here is less code solution I believe!

@IBOutlet weak var btn2: UIButton!

@IBOutlet weak var btn10: UIButton!


var arrButtons:[UIButton] = []

    override func viewDidLoad() {
        super.viewDidLoad()

        arrButtons.append(btn1)
        arrButtons.append(btn2)
        //so, on
    }

Go to button property and set state Config property selected image for UIButton so, it will replace image when isSelected property is true.

Also Bind touchUpInside event to every buttons with "btnRadioPrressed" method.

    @IBAction func btnRadioPrressed(sender: UIButton) {

        for btn in arrButons {
            btn.isSelected = false
        }
        if let index = arrButons.index(where: { $0 == sender }) {
            arrButons[index].isSelected = true
        }
    }

Hope this will help you with less code.
