The placement of Bar Button Item in UIToolBar uses Fixed Space Bar Button Item and Flexible Space Bar Button Item to adjust the space between items.
On the storyboard, you can place items on both sides by inserting the Flexible Space Bar Button Item as shown below.

The program does the same thing.

An instance of UIToolBar is toolBar.

//Left Bar Button Item
letitem1 = UIBarButtonItem(title: "Item1", style: UIBarButtonItemStyle.Plain, target:nil, action:nil)
// Flexible Space Bar Button Item
let flexibleItem = UIBarButtonItem (barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target:nil, action:nil)
// Right Bar Button Item
let item2 = UIBarButtonItem(title: "Item2", style: UIBarButtonItemStyle.Plain, target:nil, action:nil)
// Arrange the three.
let items = [item1, flexibleItem, item2]
// Replace array with UIToolBar property items
toolBar.items=items
