Parse/Swift Issue with tableviewcell "binary operator '==' cannot be applied to operands of type cell and nil"

Question

I've an issue with Parse/Swift using Xcode 6.3 beta

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath , object: PFObject) -> PFTableViewCell {
        var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! secTableViewCell

        if cell == nil
        {
            cell = secTableViewCell(style: UITableViewCellStyle.Default , reuseIdentifier: "cell")
        }
        // Configure the cell...

        cell.title.text = (object["exams"] as! String)
        cell.img.image = UIImage(named: "109.png")

        return cell
    }

The Error pointed to

 if cell == nil
        {
            cell = secTableViewCell(style: UITableViewCellStyle.Default , reuseIdentifier: "cell")
        }

binary operator '==' cannot be applied to operands of type cell and nil"

Answer 1

cell is of type secTableViewCell not secTableViewCell? (Optional<secTableViewCell>). Because it's not an optional, it cannot be nil.

If you need to test for nil, then you want to have

var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as? secTableViewCell

The thing is you should never have to test for nil. "cell" should always be the same type (in your case it should alway be secTableViewCell.
