If the tabBarMinimizeBehavior is not working in your UIKit app, it might be helpful to review the session Build a UIKit app with the new design from WWDC 2025. This session discusses how to configure the tab bar to minimize on scroll, which is a feature of the new design. The tab bar can be set to minimize when scrolling down and re-expand when scrolling in the opposite direction. Make sure you have set the topBarMinimizeBehavior to the desired direction, such as onscroll down, as demonstrated in the session.
If you are using SwiftUI, the session Build a SwiftUI app with the new design also covers how to adopt the tab bar minimize behavior using the Tab Bar Minimize Behavior modifier.
If you need further assistance, please provide more details about the specific issue you are encountering.
