try this below code

if let button = sender as? UIButton {
        if button.isSelected {
            // set selected
            button.isSelected = true
        } else {
            // set deselected
            button.isSelected = false
        }
    }

For shorthand, try this

if let button = sender as? UIButton {
     button.isSelected = !button.isSelected
}

Or simply `button.isSelected.toggle()` – C. Moulinet Mar 11 '21 at 13:23

In swift 3 you will have isSelected instead of selected. Your code looks fine just make a change.

if let button = sender as? UIButton {
    if button.isSelected {
        //for selected input            
    } else {
        //for not selected input 
    }
    button.isSelected = !button.isSelected //toggle the text box
}

@IBOutlet weak var btnCheckBox: UIButton!
@IBAction func btnCheckBoxClick(_ sender: UIButton) {
        if btnCheckBox.isSelected {
            btnCheckBox.isSelected = false
            btnCheckBox.setImage(#imageLiteral(resourceName: "icon_checkbox_inactive"), for: .normal)
        }else {
            btnCheckBox.isSelected = true
            btnCheckBox.setImage(#imageLiteral(resourceName: "icon_checkbox_active"), for: .normal)
        }
    }

It worked for me.
