Wrong indexPathForSelectedRow when using prepareForSegue - swift

Question

I'm trying to fill a tableView with some products from my MySQL database (using a PHP POST file) and at the moment everything is fine, but when I select a "Cell", the prepareForSegue is triggered, but the indexPathForSelectedRow is wrong, so it's showing a different product.
Here is my full code, I hope you can tell me something because I don't know why is this happening, I have tried a lot of things and I'm out of options...!
TableViewController.swift
import UIKit
class ListadoBuscarResultadosTableViewController: UITableViewController {
var option: String = ""
var productos = [Producto]()
var refreshControl2:UIRefreshControl!
var imageCache = [String:UIImage]()
override func viewDidLoad() {
super.viewDidLoad()
requestPost()
title = self.option
tableView.allowsMultipleSelection = true
tableView.scrollsToTop = true
self.tableView.reloadData()
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
self.navigationController?.hidesBarsOnSwipe = false
self.navigationController?.setNavigationBarHidden(false, animated: true)
}
func refresh(sender:AnyObject) {
requestPost()
self.refreshControl2.endRefreshing()
}

return 1
}

return productos.count
}
override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
// Define the initial state (Before the animation)
cell.alpha = 0.25
// Define the final state (After the animation)
UIView.animateWithDuration(1.0, animations: { cell.alpha = 1 })
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// try to reuse cell
let cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! BuscarCellTableViewCell
cell.selectionStyle = .None
//cell.nombre.text = productos[indexPath.row].nombre
//cell.marca.text = productos[indexPath.row].marca

// get the deal image
let currentImage = productos[indexPath.row].imagen
let unwrappedImage = currentImage
var image = self.imageCache[unwrappedImage]
let imageUrl = NSURL(string: productos[indexPath.row].imagen)
// reset reused cell image to placeholder

// async image
if image == nil {

func requestPost () {

if segue.identifier == "verProducto" {

Thanks in advance,

try this way...
if segue.identifier == "verProducto"{
if let indexPath = tableView.indexPathForCell(sender as! BuscarCellTableViewCell){
var detailsVC = segue.destinationViewController as! MarcaProductoViewController
}
}
