TableViewCell not displaying data

I have a table view cell that is supposed to display just a label but it wont show anything at all when I run my app. I have even tried changing the textLabels within my code but still nothing. I tried changing the cell background color as well which worked in the storyboard but when I actually run the app nothing changes. I have disconnected my view controller entirely to see if my code was the issue and still nothing happened so from what I see is its not my code but the view itself. I could be wrong though. Here is what my view loks like now: tableviewdata

  func numberOfSections(in tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 0
    }

You need to return at least 1 section, as a row is a child of a section

You have to reload data after fetch course , your table name is arg

self.arg.reloadData() when finish fetching courses

after that line

 self.courses = try decoder.decode([Courses].self, from: dat
--> self.arg.reloadData()
