Adding Buttons to the Navigation Bar with Storyboards

This article provides a step-by-step tutorial for iOS developers on how to add buttons to the navigation bar in a Storyboard-based app using Xcode 8 and Swift 3. It covers embedding a view controller in a navigation controller, adding Bar Button Items from the Object Library, configuring system items like 'Add', and setting up a modal presentation with Cancel and Save buttons.
