Invalid redeclaration of UITableViewDataSource method?

I'm trying to implement the required methods of UITableViewDataSource but I'm getting a weird error:

"invalid redeclaration of 'tableview(_:cellForRowAtIndexPath:)'"

However I'm not sure what the problem is. Here are the two relevant lines of code, the declaration of the class and conforming protocols/superclass:

class SubjectFormViewController: UIViewController,UITableViewDelegate,UITableViewDataSource

and the function declaration that's triggering the error:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) ->  UITableViewCell

You might have the same function twice in your class. Remove one of them if that is the case.

Sometimes your class extends a class that has the same function. Then, you must use "override" keyword to modify extended method, or call the method directly without defining in the class.

You have this function twice in your class. Search for it and erase one of them.
