What is the right way (Best practice) for dequeue a reusable cell in swift 3?

I'm want to dequeue a cell for use in the table view but I'm afraid that I'm doing it in the wrong way.

Currently I'm doing this way: 

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    guard let cell = tableView.dequeueReusableCell(withIdentifier: "CellID", for: indexPath) as? CustomCell else {
        return UITableViewCell()
    }

    //Configure the atributes here.            

    return cell
}

What I'm really want to know is if it is right or I have to check if the cell is nil?

var cell = tableView.dequeueReusableCell(withIdentifier: "CellID", for: indexPath) as CustomCell

if cell == nil {
    cell = CustomCell()
}

What code are correct? If none of them are right witch way is the right way?

Just forced unwrap the cell:

let cell = tableView.dequeueReusableCell(withIdentifier: "CellID", for: indexPath) as! CustomCell
...
return cell

Since you have designed the cell in Interface Builder a crash will reveal a design error.
