Horizontal Adjustment for Table Separator Lines

This example uses Xcode 7.3.1 (Swift 2.2) and iOS 9.3 simulator.

The default separator line in a tableView is like this:

Gaps exist at the left of the separator lines, white the right side of the horizontal lines touch the screen edge.

To eliminate the gaps at the left, add these lines:

tableView.separatorInset = UIEdgeInsetsZero

tableView.layoutMargins = UIEdgeInsetsZero

and this:

cell.layoutMargins = UIEdgeInsetsZero


To add gaps to the right of separators, simply add this line:

tableView.separatorInset.right = tableView.separatorInset.left


The separator lines are now centered.
