Usama I've implemented a simple button action for all those buttons which may accomplish your need. Here is the step by step implementation -

First, Declare these variables -

var buttonSelected:Bool = false

var selectedButton : UIButton?

Second, Add a single @IBAction for all buttons -

Third, Here is the action method -

@IBAction func btnSelection(_ sender: UIButton) {

    if(buttonSelected){

        if(selectedButton == sender){

            buttonSelected = false

            selectedButton = nil

            sender.setImage(UIImage(), for: UIControlState.normal)

        }
        else{

            // It's not the previously selected button
            //Do your stuff
        }

    }
    else{

        buttonSelected = true

        selectedButton = sender

        sender.setImage(UIImage.init(named: "checkmark"), for: UIControlState.normal)

    }

}

Hope it will help you to start with.

Make the Other button disabled in particular scenario. isUserInteractionEnabled = false

Answer 3

You could rename updateCheckImageOnClick(button: UIButton) to something generic in order to add some logic inside, like:

func update(button: UIButton) {
    isBoxClicked = !isBoxClicked

    button.setImage(isBoxClicked ? UIImage(named: "checkmark") : UIImage(), for: UIControlState.normal)

    if button == bestSellerButton {
        trendingButton.isEnabled = false
        lowToHighButton.isEnabled = false
        highToLowButton.isEnabled = false
    } else if button == trendingButton {
        bestSellerButton.isEnabled = false
        lowToHighButton.isEnabled = false
        highToLowButton.isEnabled = false
    } else if button == highToLowButton {
        trendingButton.isEnabled = false
        lowToHighButton.isEnabled = false
        bestSellerButton.isEnabled = false
    } else {
        bestSellerButton.isEnabled = false
        trendingButton.isEnabled = false
        highToLowButton.isEnabled = false
    }
}
