iOS Swift Dequeued Reusable Cell not showing up - ios

Question

I followed a tutorial earlier to get the basics of the Storyboard down and I'm using that code as a reference to write the app I'm working on. I want to test my prototype cell layout, but even though I set a value to the array at viewDidLoad it still refuses to show anything.
import UIKit
class DetailViewController: UIViewController {
var cards = [Card]()
#IBOutlet weak var cardsTableView: UITableView!
#IBOutlet weak var detailDescriptionLabel: UILabel!
var detailItem: AnyObject? {
didSet {
// Update the view.
self.configureView()
}
}
func configureView() {
// Update the user interface for the detail item.
if let detail: AnyObject = self.detailItem {
if let label = self.detailDescriptionLabel {
label.text = detail.description
}
}
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cards.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
//példányosítunk egy cellát
let cell = tableView.dequeueReusableCellWithIdentifier("CardCell", forIndexPath: indexPath) as CardCell
//kivesszük a sor adatait a listából
let card : Card = self.cards[indexPath.row]
cell.setCardNumber(card.number)
cell.layer.cornerRadius = 8
return cell
}
override func viewDidLoad() {
super.viewDidLoad()
self.cards = [Card(number: 123456789,type: 1)]
dispatch_async(dispatch_get_main_queue(), {
self.cardsTableView.reloadData()
})
self.configureView()
}
}
I started from a Master-Detail structure and I set the class of the Detail Scene to DetailViewController and the class and identifier of the Prototype to CardCell
class Card{
let number: Int
let type: Int
init(number: Int, type: Int){
self.number = number
self.type = type
}
}
import UIKit
class CardCell: UITableViewCell {
#IBOutlet weak var cardNumber: UILabel!
func setCardNumber(number: Int){
cardNumber.text = String(number)
}
}
I'm sure it's something basic, but I've been messing with this for the second day now. Any suggestions are appreciated.

Answer 1

you have to set the dataSource for the table view, i guess the delegate methods get never called.
Additionally add UITableViewDataSource, not necessary but more declarative than just the implementation
class DetailViewController: UIViewController, UITableViewDataSource {
