Apple Seeds Fourth Developer Betas of iOS 26 and iPadOS 26

Apple today provided developers with the fourth betas of iOS 26 and iPadOS 26 for testing purposes, with the updates coming two weeks after Apple seeded the third betas.

iOS 26 Feature
Registered developers can download the new beta software using the Software Update section of the Settings app.

‌iOS 26‌ and ‌iPadOS 26‌ feature Apple's new Liquid Glass design aesthetic, with a focus on translucency and glass-like interface elements. The design extends to the Lock Screen, Home Screen, and Control Center, along with menus and buttons in apps.

Apple's software includes features for apps like Messages, Phone, Shortcuts, and Apple Music, along with new Apple Intelligence features, a revamp for CarPlay, and more. In ‌iPadOS 26‌, there's a whole new multitasking system that supports multiple app windows for a more Mac-like experience.

For more on the features in ‌iOS 26‌, we have a dedicated iOS 26 roundup and a separate iPadOS 26 roundup. Several new features were found in beta 2 and we rounded them up, plus we did the same thing for beta 3.

Why do people keep talking about a liquid glass slider? Apple is never going to do that (and that’s assuming it’s something that could easily be done and would actually work).

It’s glassier than B3, seems to be refined with more of an edge around some of the buttons that makes it clear but readable still.
Agree, it's better and more liquid glass than B3, thank god they're listening.

Hopefully there is finally a slider for Liquid Glass effect or that it was rolled back to something similar on Beta 1, just somehow tweaked with better visibility. Personally, I did not have any legibility issues so I would not mind and would even love if Apple brings back the Beta 1 look.
