Apple has seeded iOS 27 beta 3 to developers, and the update is one of the more feature-packed test builds of the cycle. Released on July 6, 2026 as build 24A5380h, beta 3 centers on the long-awaited Siri AI, deeper Apple Intelligence integration, and a set of Liquid Glass refinements, alongside a list of smaller quality-of-life changes across the system.
Key Takeaways
- iOS 27 beta 3 arrived July 6, 2026 (build 24A5380h) for developers.
- It emphasizes the new Siri AI, Apple Intelligence, and Liquid Glass design tweaks.
- Safari gains four new capabilities, and Reminders gets a redesigned app icon.
- The public release is expected in September alongside the new iPhone lineup.
Siri AI and Apple Intelligence
The upgraded, more conversational Siri is the star of this build. It can handle more complex, multi-step requests and draw on personal context to give more relevant answers. According to 9to5Mac, Apple Intelligence assets needed to be re-downloaded when moving to beta 3, which temporarily reset access to the new Siri functionality until the models finished installing. Beta 3 also makes the Siri voice customization sliders for pace and expressivity functional, and the Camera app's Siri Mode now requires the updated Siri version. The forced re-download is a reminder that the new Siri leans heavily on downloadable models: simpler requests are handled on-device for speed and privacy, while more demanding queries are routed to Apple's cloud.
Four new Safari features
Safari picks up a notable batch of additions in beta 3:
- Automatic tab organization
- Bookmark browsing by topic
- Page-change notifications for sites you're watching
- The ability to create custom extensions
Together, these lean into Safari as a smarter, more organized browser rather than a static window.
Design and app changes
Reminders adopts an updated app icon that swaps its solid color bullet points for hollow, colored ones, a subtle but noticeable refresh. Apple also softened the specular highlights on app icons, which changes how clear and tinted icons catch the light under the Liquid Glass look. Elsewhere, the Control Center status bar now shows your cellular network signal and type even when you're connected to Wi-Fi, and Shortcuts can now launch directly into an action view for editing alongside natural-language input.
How it fits the broader rollout
Beta 3 is part of a coordinated wave of Apple beta releases. The same day, watchOS 27 beta 3 added a standalone Siri app and Siri AI to the Apple Watch for the first time. This continues the steady build-out that started earlier in the cycle, following iOS 27 beta 2's Write with Siri, Wallet insights, and RCS improvements. Apple also seeded macOS 27 beta 3 the same day, adding new Golden Gate Bridge wallpapers and screensavers that play on the release's Golden Gate branding, underscoring how tightly the company syncs its platform betas.
Why It Matters
Beta 3 is where iOS 27's headline feature, the rebuilt Siri, starts to feel real for testers, and the Safari and Control Center changes signal the polish phase before public release. A public beta is expected later in July, with the final version shipping in September alongside Apple's new iPhones. If you have been waiting to judge whether the new Siri lives up to Apple's WWDC promises, beta 3 is the first iOS build where you can meaningfully put it through its paces. That said, developer betas are pre-release software and can be unstable, so they are best kept off a primary device. A more polished public beta, expected later in July, is the safer way for most people to get an early look before the September launch.
