I have attached two images of two screens below. In one screen, bar button are enclosed within separate, distinct, rounded-rectangle 'liquid glass' capsules. In other screen, bar buttons are enclosed within separate, distinct, rounded-rectangle "liquid glass" capsules. They are not visually merged into one larger capsule.
Both are having same code. But why it is not same ?
Buttons with text labels are not merged with buttons with images. This is documented somewhere or mentioned in one of the WWDC 2025 videos (I forget which one).
Here's a big question for you - how did you get the Back button tinted? As of iOS 26.0 beta 4, there is no way to tint a standard back button. Did you add your own button to look and work like a back button?
