Table View cellForRowAtIndexPath warning

Question

I have updated my code to swift 3.0 and get a warning on the following line:

func tableView(_ tableView: UITableView, cellForRowAtIndexPath indexPath: IndexP         


        

Answer 1

I had a similar problem, and found that if you remove the space between the underscore before tableView, from this

func tableView(_ tableView: ...

to this

func tableView(_tableView: ...

strangely the warning goes away...

Answer 2

Just add the declaration of implementing UITableViewDataSource protocol to the class definition like this:

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {}

Answer 3

In swift 3.0 the signature for the datasource changed to:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell

Notice the difference between cellForRowAtIndexPath indexPath: IndexPath and cellForRowAt indexPath: IndexPath

I'm using the new method without any warnings, hope this will solve your problem.

Cheers.
