Answer 1

swift 5, Xcode 11 Update

place this inside viewDidLoad()

yourTableView.separatorInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)

for edge to edge separator just set the value of left and right to 0.

by the way change the "yourTableView" to your tableView Outlet name.

Answer 2

For Swift 3 :

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    if cell.responds(to: #selector(setter: UITableViewCell.separatorInset)) {
        cell.separatorInset = UIEdgeInsets.zero
    }
    if cell.responds(to: #selector(setter: UITableViewCell.layoutMargins)) {
        cell.layoutMargins = UIEdgeInsets.zero
    }
    if cell.responds(to: #selector(setter: UITableViewCell.preservesSuperviewLayoutMargins)) {
        cell.preservesSuperviewLayoutMargins = false
    }
}

Answer 3

For Swift in iOS 9+

If using a custom UITableViewCell:

override var layoutMargins: UIEdgeInsets {
    get { return UIEdgeInsetsZero }
    set(newVal) {}
}

then for your UITableView in viewDidLoad:

self.tableView?.separatorInset = UIEdgeInsetsZero;
self.tableView?.layoutMargins = UIEdgeInsetsZero;

2. Go to Atributes Inspector
3. Go to Separator and change it to "custom Insets"
4. Set left and / or right fields. (By default left: 15, right: 0)

Look how it works (using left: 100):
