TableViewCell Unresolved Identifier when creating cell

in my Xcode Project, I have the main storyboard set up with a table view and a prototype cell with the identifier set to "cell". The table view has a data source outlet and a delegate outlet.
Yet, my build crashes every time because of an "unresolved identifier" when I create the table view in line 11 (see code below).

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource 
{

let array = createArray()

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return(validDeck.count)
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    cell = UITableViewCell(style: UITableViewStyle.default, reuseIdentifier: "cell") |"ERROR: Unknown Identifier 'cell' "
    cell.textlabel?.text = ""
    return cell
}

Does anybody know this error and is willing to help?

You never initialize UITableViewCell instances directly.

In viewDidLoad:

tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")

and then:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for indexPath: indexPath)
    cell.textlabel?.text = ""
    return(cell)
}

Use below code for swift 3.*

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return validDeck.count // assuming count must be greater then 0
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier("cell") as! UITableViewCell

cell.textlabel?.text = "Cell tittle"
    return cell
}
