ERROR: Method does not override any method from its superclass - ios

Question

I'm creating a table view ui programmatically and the code i followed has no problems but mine kept telling me i have the error above? Please help
The error shows that it is at this line: override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
This is a fragment of my code:-
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
return tableView.dequeueReusableCell(withIdentifier: "cellId", for: indexPath as IndexPath)
}
class MyCell: UITableViewCell {
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
setupViews()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setupViews() {
}
}

Answer 1

Im not sure but seem you have tableView in UIViewController? If like this, we don't need override before func cellForRowAtIndexPath . Just remove override text.

Answer 2

cellForRowAtIndexPath is Swift 2 code. Please look for tutorials providing contemporary code.
The syntax of Swift 3+ is
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
The override keyword is only required if the class is a subclass of UITableViewController

Answer 3

If you use UIViewController, just add UITableViewDataSource and UITableViewDelegate methods as like below example and don't include override keyword:
class MyViewController: UIViewController , UITableViewDataSource, UITableViewDelegate{
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
}
//Other UITableViewDataSource and UITableViewDelegate methods goes here
}
If you use UITableViewController, you can override the UITableViewDataSource and UITableViewDelegate methods as like below example:
class MyTableViewController: UITableViewController{
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
}
//override other UITableViewDataSource, UITableViewDelegate methods here
}
Hope it helps!
