Hi. I've noticed that on iOS 27 the UITabBarItem badge goes behind the tab image during tab selection.
Here is a little screen recording of a simple Storyboard project with just a UITabBarController and two child UIViewControllers. On the left is iOS 26.5 and on the right is iOS 27.0 beta 6.
While filled icons look more or less ok, the outline icons look the most concerning with this new behaviour.
So, the question is whether this is a bug or a feature?
This behavior is expected on iOS 27 beta buids, and there is no API to change the badge layering or restore the previous behavior.
If this visual behavior impacts specific outline icons in your app, please file a report via Feedback Assistant. Please share the Feedback number here once submitted.
