Apple dropped iOS 26 beta 4 for developers Tuesday. It tweaks the Liquid Glass redesign and brings back AI-powered notification summaries for news.
The update hits just before the public beta expected later this week. Devs get early access to prep their apps ahead of the big rollout.
The new beta adds a “Welcome” splash screen on update and intro screens for Siri’s AI notification summaries and iOS 26’s revamped Camera app. 
Apple paused AI notification summaries earlier this year after the BBC flagged a major headline error. Now the feature is back — with a warning that “Summarization may change the meaning of the original headlines” and users should “Verify information.”
Apple’s AI notification setup screen says:
“Summarization may change the meaning of the original headlines”
“Verify information.”
The Liquid Glass UI sees further fine-tuning. Beta 4 reverses last beta’s pullback on transparency, updating apps like App Store, Photos, and Apple Music. The Notification Center now adds dynamic tinting when you scroll.
The update also rolls out a new dynamic wallpaper that shifts colors and fresh CarPlay wallpaper options.
Public release notes aren’t live yet. Expect more fixes hidden under the hood.
Apple also launched iPadOS 26 beta 4, macOS 26 beta 4, watchOS 26 beta 4, tvOS 26 beta 4, visionOS 26 beta 4, and Xcode 26 beta 4 in tandem.
