Find out the parent view of a clicked button in swift

I you don't want to create a custom class and also don't want to use accessibilityHin:

    func performAction(_ sender : AnyObject?)
{
    let cell = sender?.superview??.superviewOfClassType(UITableViewCell.self) as! UITableViewCell
    let tbl = cell.superviewOfClassType(UITableView.self) as! UITableView
    let indexPath = tbl.indexPath(for: cell) 
    let myData = myDataArray[indexPath.row]
    ...
}

Please try the following

sender.superview
