deselect other radio buttons in tableView

[23hassine1]

I have tried radioButtons[radioButton.tag].deselectOtherButtons() in @objc @IBAction private func logSelectedButton(radioButton : DLRadioButton) function but it doesn't work I tried also
method 2:
for i in 0..<radioButtons.count{
if (radioButton.tag != i){
radioButtons[i].isSelected=false
}
}
it does work but when selected Radiobutton all other radioButtons gets selected then deselected
I am using swift 3 any help is appreciated
