iOS 8 UITableView separator inset 0 not working: how to remove padding?

Hi everyone! I'm writing an app for iOS 8 in Swift, and I've run into a problem that's driving me crazy. I want the separator lines in my UITableView to have no padding, meaning they go from the far left edge to the far right edge. It seems simple: I set `tableView.separatorInset = UIEdgeInsetsZero` or `tableView.separatorInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)`, but it doesn't work — the left padding still remains. I've tried everything: setting the inset in `viewDidLoad`, in `cellForRowAtIndexPath` for each cell, even tried overriding `layoutMargins` on the cell. Nothing helps. Here's my code: ```swift override func viewDidLoad() { super.viewDidLoad() tableView.separatorInset = UIEdgeInsetsZero tableView.separatorStyle = .SingleLine } ```
