title: Defining 'UITableViewCell' variable in Swift 2.0
body: <p>I am trying to create UITableViewCell type variable with swift, these are my codes:
  <pre> func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
          return dwarves.count
      }</p>
  
  <code>func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell {
      var cell = tableView.dequeueReusableCellWithIdentifier(simpleTableIdentifier)! as UITableViewCell
      if (cell == nil) {
          cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: simpleTableIdentifier)
      }
  
      cell.textLabel?.text = dwarves[indexPath.row]
      return cell
  }
  </code></pre>
  
  <p></p>
  
  <p>In 7th line <strong>if (cell == nil)</strong>, it gives me an error that <strong>Value of type 'UITableViewCell' can never be nil, comparison isn't allowed</strong>.
  It can't be replaced by <strong>if ( !cell )</strong>. How should I fix the codes?</p>
