Change data in DetailViewController Swift

Question

Im trying to create a master-DetailView application and I'm stuck at the moment, Im trying to create the template for my data . For example i would like to have an array that will control on the data (a label for example / an image ) manually and change by the indexPath,So every cell will have a different dat presented on, Here i connected all the labels and images i want to control their data:

  class BarProfileTableViewController: UITableViewController,MKMapViewDelegate{

    @IBOutlet var Distance: UILabel!
    @IBOutlet var headerImage: UIImageView!
    @IBOutlet var Address: UILabel!
    @IBOutlet var ProfileMapView: MKMapView!

    @IBOutlet var BarNameLBL: UILabel!

    @IBOutlet var streetNameLBL: UILabel!

    var photos = ["Shalvata cover","litzmancover"]
    var barName = String()
    var barImage = UIImage()
    var streetName = String()
    var images: [UIImage] = []

    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(true)
        ///headerImage.image = barImage
        BarNameLBL.text = barName
        streetNameLBL.text = streetName
        navigationItem.title = barName
    }
 override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        let item = photos[indexPath.row]
        headerImage.image = UIImage(named: "\(item).png")
    }

Answer 1

What about this:

var photos = ["day","night"]

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let item = photos[indexPath.row]
    headerImage.image = UIImage(named: "\(item).png")
}

Is this what you're looking for?
