Swift out of range.... with tableView[indexPath]

I'm getting trouble with out of range error...

The error occurs in cell.creditLabel.text = numOfDays[(indexPath as NSIndexPath).row] + "days".

And if I put tableView.reloadData() after cell.nameLabel.text = nameArray[(indexPath as NSIndexPath).row]

then nothing shows up in the simulator...

How can I fix this problem..?

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return self.nameArray.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

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


    cell.nameLabel.text = nameArray[(indexPath as NSIndexPath).row]

    cell.creditLabel.text = numOfDays[(indexPath as NSIndexPath).row] + "days"
    cell.levelLabel.text = creditArray[(indexPath as NSIndexPath).row]

    cell.layoutIfNeeded()

    return cell
}

Check that the arrays have the correct amount of items:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return self.nameArray.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

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


    cell.nameLabel.text = nameArray[indexPath.row]

    if numOfDays.count < indexPath.row {
        cell.creditLabel.text = numOfDays[indexPath.row] + "days"
    }

    if creditArray.count < indexPath.row {
        cell.levelLabel.text = creditArray[indexPath.row]
    }

    return cell
}

Also, I have removed the unnecessary casting of indexPath and the layoutIfNeeded (the cell will always draw again, since it is new).

Number of elements in "numOfDays" array are less than number of elements in "nameArray" array

You need to check your arrays. From what I can see here, numOfDays have less elements then nameArray. Also, while you are there check creditArray as well :)

Also, cast to NSIndexPath is not necessary.
