Answer 1

Swift 5

If you want to add space between two Bar Button items then add a flexible space in between, the two buttons will be pushed to the left and right edge as the flexible space expands to take up most of the toolbar.

For Example:

let toolBar = UIToolbar()

var items = [UIBarButtonItem]()

let backBarButton =  UIBarButtonItem(image: UIImage(named: "icon-back.png"), style: .done, target: self, action: #selector(backButtonTapped))

let nextBarButton =  UIBarButtonItem(image: UIImage(named: "icon-next.png"), style: .done, target: self, action: #selector(nextButtonTapped))

let spacer = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)

items.append(backBarButton)
items.append(spacer)
items.append(nextBarButton)

toolBar.setItems(items, animated: true)
