Start IndexPath from one

I need to start it from one to show the corresponding data of the BD

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    vcName = values[indexPath.row]["idCategoria"] as! String
    print(vcName)
    //performSegueWithIdentifier("show", sender: self)
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {

    if (segue.identifier == "show") {

        if let vc: ViewController = segue.destinationViewController as? ViewController {
            vc.idCategoria = vcName
        }

    }
}
