The concept of a navigation stack is discussed in the context of UIKit and Assistive Access at WWDC. In the session titled "Make your UIKit app more flexible," it is explained how view controllers are pushed onto a navigation stack when a tab is selected. This allows for customization of the view controllers that are part of the navigation stack by implementing the UITabBarController delegate method. This approach is part of adopting container view controllers like UISplitViewController and UITabBarController to ensure app flexibility (Make your UIKit app more flexible).
Additionally, in the session "Customize your app for Assistive Access," it is mentioned that when navigating into a view, the Assistive Access back button allows users to traverse back up the app's navigation stack without additional work, streamlining the user experience (Customize your app for Assistive Access).
These sessions highlight how navigation stacks are utilized and customized within different contexts in iOS app development.
Make your UIKit app more flexible
Find out how your UIKit app can become more flexible on iPhone, iPad, Mac, and Apple Vision Pro by using scenes and container view controllers. Learn to unlock your app’s full potential by transitioning from an app-centric to a scene-based lifecycle, including enhanced window resizing and improved multitasking. Explore enhancements to UISplitViewController, such as interactive column resizing and first-class support for inspector columns. And make your views and controls more adaptive by adopting new layout APIs.
Customize your app for Assistive Access
Assistive Access is a distinctive, focused iOS experience that makes it easier for people with cognitive disabilities to use iPhone and iPad independently. In iOS and iPadOS 26, you can customize your app when it’s running in Assistive Access to give people greater ease and independence. Learn how to tailor your app using the AssistiveAccess SwiftUI scene type, and explore the key design principles that can help you create a high-quality Assistive Access experience for everyone.
