Passing data from tableView to ViewController in Swift - swift

Question

I have an App that i'm trying to adapt exactly how i want
I have been following a Youtube tutorial of Seemu Apps to make it but I need to finish it adding an optional ViewController
This app has 2 tableViews showing vehicles and if we click in one row of the first tableView then second tableView will show us a list of selected vehicles.
Here is what we have until now: (image link , because i haven't got ten points reputation on stackOverFlow)

All is running perfect, but i want to be able to display information in an optional detailViewController (label with a detailed description of each vehicle and a bigger image of this ) depending of which vehicle we click in the secondTableViewControlle (or modelViewController in the App) exactly how i was following in the tutorial between tableViews
i know that we need to passing data through prepareForSegue method , i have understood this making the steps in the tutorial but when we have 2 tableviewControllers
For example : if we want to display a last viewController with information of Ferrari 458 and a great picture of this car
What do we need to do exactly to show information of each vehicle?
PD : I'm beginner in the programming world, maybe i would need to see it in a very simple way
The whole code:

Answer 1

Try this.
ModelViewViewController
var selectedImage:String?
var selectedLabel:String?
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
println("Row \(indexPath.row)selected")
selectedImage = self.tableData[indexPath.row]
selectedLabel = self.tableData[indexPath.row]
performSegueWithIdentifier("detailView", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if(segue.identifier == "detailView") {
var vc = segue.destinationViewController as DetailViewController
vc.img = selectedImage
vc.lblDetail = selectedLabel
}
}
class DetailViewController: UIViewController {
#IBOutlet var imgDetail: UIImage!
#IBOutlet var lblDetail: UILabel!
var img:String?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
imgDetail = UIImage(named: img)
}
This should work.
