It is hard to find the cause of crashes even when properly formatted crash logs given. Can you show the crash log properly formatted and your code?

It would be specially important to have the full ShiftsListViewController tableView(:cellForRowAt:) where the crash apparently occurs.

Code attachedBelow

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if list.count <= 0 {
            return UITableViewCell()
        }
