Swift version: 5.0
navigationItem property of your view controller has two properties responsible for displaying multiple bar button items on either side of
leftBarButtonItems for the left-hand side and
rightBarButtonItems for the right-hand side. These are not to be confused with
rightBarButtonItem, which are older properties designed to store single items.
One confusion when working with arrays of bar button items is the order in which they are displayed: they fill from the outside in. So, when using
leftBarButtonItems they appear in the order of your array, and when using
rightBarButtonItems they appear in reverse order.
For example, here’s some code to display a share button and an add button on the right-hand side of the navigation bar, and the add button will be on the right of the share button:
let share = UIBarButtonItem(barButtonSystemItem: .action, target: self, action: #selector(shareTapped)) let add = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped)) navigationItem.rightBarButtonItems = [add, share]
