indexing dictionary in prepareForSegue

Right now, only the first list is showing, how do I index it that each cell will show the next list in the array from the dictionary. Thank you in advance

destination controller code

var list: List? @IBOutlet weak var scientificPhoto: UIImageView! @IBOutlet weak var secondPhoto: UIImageView! @IBOutlet weak var scientificText: UITextView! @IBOutlet weak var scientificTitle: UILabel!

override func viewDidLoad() {
    super.viewDidLoad()

    if list != nil {

        scientificTitle.text = list!.title
        scientificPhoto.image = list!.firstImage
        secondPhoto.image = list!.secondImage
        scientificText.text = list!.description

    }

Table View controller code

import UIKit

class ScientificTableViewController: UITableViewController {

var miracles = ScientificLibrary()
var names = [String]()
var photos = [UIImage]()


override func viewDidLoad() {
    super.viewDidLoad()

    names = ["Universe", "Seas", "Clouds", "Tectonics", "Bees", "Rome", "Arithmetics"]      
    photos = [UIImage(named: "galaxy")!, UIImage(named: "seas")!, UIImage(named: "cloud")!, UIImage(named: "view")!, UIImage(named: "bees")!, UIImage(named: "rome")!, UIImage(named: "arithmetics")!]   
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return names.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! ScientificTableViewCell

    cell.photo.image = photos[indexPath.row]
    cell.Title.text = names[indexPath.row]
    return cell
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "showMiracle" {
        let scientificDetailTableViewController = segue.destinationViewController as! ScientificDetailTableViewController

        scientificDetailTableViewController.list = List(index: 0)

    }

}

}

Hey Mohamed Ibrahim,

I believe you are performing this segue from a UITableViewCell to another ViewController? If so, you can get the indexPath of the selected cell from tableView using

tableView.indexPathForSelectedRow()

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "showMiracle" {
        let scientificDetailTableViewController = segue.destinationViewController as! ScientificDetailTableViewController
        let indexPath = tableView.indexPathForSelectedRow()
        scientificDetailTableViewController.list = List(index: indexPath.row)
}

Good Luck P.S. I'm not entirely sure how your code is working so this is not a cut and paste solution, but rather a step in the right direction.
