UITableView, Separator color where to set?

Swift version:

override func viewDidLoad() {
    super.viewDidLoad()

    // Assign your color to this property, for example here we assign the red color.
    tableView.separatorColor = UIColor.redColor()
}

- (void)viewDidLoad
{
   [self.tableView setSeparatorColor:[UIColor myColor]];
}

I hope that helps - you'll need the self. to access it, remember.

Swift 4.2

tableView.separatorColor = UIColor.red

Now you should be able to do it directly in the IB.

Not sure though, if this was available when the question was posted originally.
