自定义表格单元格不符合NilLiteralConvertible Swift Xcode 6 Beta 5

Question

So before i was registering Nib table cells like this through out all beta's but they must have changed a few things and i'm unsure as to how to make this work now, i've tried removing it from the if statement but when using tags for textfields, the textfields reset the first time when typing in them..

It displays as NSObject does not conform to NilLiteralConvertible.

var mailCell: mailTableCell = tableView!.dequeueReusableCellWithIdentifier("mailCell", forIndexPath: indexPath) as mailTableCell

        if mailCell == nil {
            var nib: NSArray = NSBundle.mainBundle().loadNibNamed("mailTableCell", owner: nil, options: nil)
            mailCell = nib.objectAtIndex(0) as mailTableCell

        }

Answer 1

You don't need the if statement and associated code. dequeueReusableCellWithIdentifier:forIndexPath: always returns a valid cell.

From the documentation -

Return Value

A UITableViewCell object with the associated reuse identifier. This method always returns a valid cell.
