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