iOS 8 UITableView separator inset 0 not working

Question

I have an app where the UITableView\'s separator inset is set to custom values - Right 0, Left 0. This works perfectly in iOS 7.

This is the code that's working for me, in Swift:

override func viewDidLoad() 
{
    super.viewDidLoad()
    ...
    if tableView.respondsToSelector("setSeparatorInset:") {
        tableView.separatorInset = UIEdgeInsetsZero
    }
}

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell,forRowAtIndexPath indexPath: NSIndexPath)
{
    if cell.respondsToSelector("setSeparatorInset:") {
        cell.separatorInset.left = CGFloat(0.0)
    }
    if tableView.respondsToSelector("setLayoutMargins:") {
        tableView.layoutMargins = UIEdgeInsetsZero
    }
    if cell.respondsToSelector("setLayoutMargins:") {
        cell.layoutMargins.left = CGFloat(0.0)
    }
}

This seems the cleanest to me (for now), as all the cell/tableView edge/margin adjustments are done in the tableView:willDisplayCell:forRowAtIndexPath: method, without cramming unneccessary code into tableView:cellForRowAtIndexPath:.

Btw, I'm only setting the cell's left separatorInset/layoutMargins, because in this case I don't want to screw up my constraints that I have set up in my cell.

Code updated to Swift 2.2 :

 override func viewDidLoad() {
   super.viewDidLoad()       

    if tableView.respondsToSelector(Selector("setSeparatorInset:")) {
      tableView.separatorInset = UIEdgeInsetsZero
        }
    }

 override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell,forRowAtIndexPath indexPath: NSIndexPath) {
        if cell.respondsToSelector(Selector("setSeparatorInset:")) {
            cell.separatorInset.left = CGFloat(0.0)
        }
        if tableView.respondsToSelector(Selector("setLayoutMargins:")) {
            tableView.layoutMargins = UIEdgeInsetsZero
        }
        if cell.respondsToSelector(Selector("setLayoutMargins:")) {
            cell.layoutMargins.left = CGFloat(0.0)
        }
    }
