    This is probably the most common issue the new Swift developers can have, there are hundreds of answers on SO, you can find a very detailed explanation at some of them or at every Swift cookbook. What interests me is the part "comment part is not available now", could you elaborate ? – A-Live Jun 27 '16 at 15:05

Way too much code. 

let cell = UITableViewCell(style: .Default, reuseIdentifier: cellId)

It won't be nil unless your tableview's reuseIdentifier isn't correct.

I would use

let cell = tableView1.dequeueReusableCellWithIdentifier(cellId, forIndexPath: indexPath) as! UITableViewCell

That means that the cell with the correct ID will be placed into the correct space on the UITableView. Also, I think that having tableView at the front might have caused the error, so I changed it to tableView1.
