swift table view not populating

Im having some trouble with populating my table view from my array. While my array is not empty (I tried printing it in the console and there are the data I wanted), the tableView is not populating with what I wanted but instead it is empty. I am wondering if I have done anything wrong here to cause that

Here's my code:

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return numberOfGamesPlayedRecently
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
   var cell = UITableViewCell()
    // display our ranked data
    cell.textLabel?.text = "\(tableData[indexPath.row])"
    return cell
}

where numberOfGamesPlayedRecently is an int and my tableData is a array of epoch time

Thanks!

I stumbled across your question while having the same issue myself. I was able to resolve my tableView not populating by:

1. setting the ViewController as a UITableViewDataSource in the class declaration and
2. in the ViewDidLoad method, setting the ViewController as the datasource like so: tableView.dataSource = self

First off, as Caroline said, it's best practice to use a storyboard and use let cell = tableView.dequeueReusableCellWithIdentifier("CellIdentifier", forIndexPath: indexPath) as! UITableViewCell both to let you modify the cell in the storyboard and to greatly increase memory performance with large tables.

Second, I don't think the tables are connected. Your code all seems right, and it may be worthwhile to set some other property of the cell (like the background color), but it does seem like they aren't connected. Go to your storyboard, highlight the table view (not the view overall), open your property inspector, go to the "Custom Class" tab (third from the left, it looks like a small newspaper), and set the class property to the name of your custom UITableView class.

If you are using a storyboard, you should be using something like this to get a reference to the current cell:

let cell = tableView.dequeueReusableCellWithIdentifier("CellIdentifier", forIndexPath: indexPath)
as! UITableViewCell

Have you set your delegate and datasource? If you are using a UITableViewController you don't need to do that, but otherwise you do.

You should probably do tutorials to make sure you know how table views work.
