Will there be memory management issue by instantiating UITableViewCell using class method?

    extension SettingsTableViewController {
         override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
             let cell = SettingsTableViewCell.getSettingTableViewCell(tableview: tableView, indexPath: indexPath)
             return cell
         }
    }
    class SettingsTableViewCell: UITableViewCell {
         static let identifier = "SettingsTableViewCell"
         public class func getSettingTableViewCell(tableview: UITableView, indexPath: IndexPath) -> SettingsTableViewCell {
             if let cell = tableview.dequeueReusableCell(withIdentifier: self.identifier, for: indexPath) as? SettingsTableViewCell {
                 return cell
             }
             return SettingsTableViewCell()
         }
     }

By instantiating a tableView Cell with this approach. Are we going to face any memory management related issue?

In short, no.

You don't need to do that manually when you register your cell class with the tableview, however:

// e.g. in viewDidLoad
tableView.register(SettingsTableViewCell.self, forCellReuseIdentifier: "cell")

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! SettingsTableViewCell
    return cell
}
