Having trouble responding to selections when using a UITableView and swift - ios

Question

I have a question about responding to selections with a UITableView. I want to create a FAQ and trigger an action when the user selects a row. I'm just testing it right now, and set it to print a log message when the user selects one of the rows on the table view. However, in the simulator nothing happens.
I'm not sure what I am doing wrong. Can someone please help enlighten me?
Thanks in advance. Below is my code.
class FirstViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
let iEdCafeVid = [
("temp", "temp"),
("temp", "temp"),
("temp", "temp") ]
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return iEdCafeVid.count //the number of spots in the array
}
//uses the numberOfRowsInSection method
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell //because creating as AnyObject.
//var cell = UITableViewCell() //instantiating class, but should use the dequeue option.
//need to add the prototype cell in the storyboard before the dequeue option will work.
//creating touple (desciptions of the cell content parts)
let (videoTitle, subtitle) = iEdCafeVid[indexPath.row] //index parth is the value (i.e. the array in this case) that we created in the numberOfRowsInSection method.
cell.textLabel.text = videoTitle
cell.detailTextLabel?.text = subtitle
//retrieve image
var cellImage = UIImage(named: "CellIcon")
cell.imageView.image = cellImage
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
println("user has selected a cell")
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
