iOS Swift - How to change background color of Table View?

Question

I have a simple table view, I can change the colors of cells, but when trying to change the color of Table View (Background part) it is not working... I tried it via Storyboard.

Answer 1

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
    cell.contentView.backgroundColor = UIColor.yellowColor()
}

Swift 3

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    cell.contentView.backgroundColor = UIColor.yellow
}
