tableview using array not working - xcode 7.3 - ios

Question

I'm designing an app for my school and I am trying to make a simple directory using a tableview within a view controller. I began by trying to make objects, but then switched to a more simple array, still without any luck. I do not know if it is a problem with the code or with the storyboard. Here is the code for the viewcontroller:
import UIKit
class DirectoryViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var backButton2: UIButton!
#IBOutlet weak var directoryTableView: UITableView!
// #IBOutlet weak var nameLabel: NSLayoutConstraint!
// let searchController = UISearchController(searchResultsController: nil)
// var directoryObjects: NSMutableArray! = NSMutableArray()
var names = ["Teacher 1", "Teacher 2", "Teacher 3"]
override func viewDidLoad() {
super.viewDidLoad()
/*
self.directoryObjects.addObject("Teacher 1")
self.directoryObjects.addObject("Teacher 2")
self.directoryObjects.addObject("Teacher 3")
self.directoryTableView.reloadData()
*/
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
// Mark - tableview
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return 3
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let directoryCell = self.directoryTableView.dequeueReusableCellWithIdentifier("directoryCell", forIndexPath: indexPath) as! DirectoryTableViewCell
// directoryCell.directoryLabel.text = self.directoryObjects.objectAtIndex(indexPath.row) as? String
directoryCell.directoryLabel.text = names[indexPath.row]
return directoryCell
}
#IBAction func backButton2Tapped(sender: AnyObject) {
self.dismissViewControllerAnimated(true, completion: nil)
}
}
Here is the code for the DirectoryTableViewCell:
import UIKit
class DirectoryTableViewCell: UITableViewCell {
#IBOutlet weak var directoryLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
/*
func directoryTableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
}
*/
}

You have to set the delegates. The easiest way is in the code.
In viewDidLoad add:
directoryTableView.delegate = self
directoryTableView.dataSource = self
This will allow those tableView functions to get called.
I'd also recommend changing:
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return 3
}
to:
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return names.count
}
