On the first day of the WWDC developer conference, Apple released the first developer beta of its new operating system. This year, that means that the first release of iOS 27 outside Cupertino came on June 8, 2026.
The pattern goes like this: Apple releases developer-only betas for the first month or so, and then starts releasing the same build for both developers and public beta testers. Based on historical precedent, we expect the third or fourth beta to be the first one to go out to public beta testers rather than just developers.

Updated July 20, 2026: The fourth beta of iOS 27 has been released. Developers can grab it today, and Public Beta testers will likely be able to download it in the next 24 hours.
What’s new in iOS 27
The big iOS 27 release this year is focused on three main areas:
- Trust and Safety – New parental controls to keep kids safe and control screen time.
- Performance and refinement – Speeding everything up, improving efficiency, tweaking interfaces, and addressing dozens of small user requests.
- Apple Intelligence and Siri – Entirely new Apple Intelligence models improve AI throughout the system, and a brand-new Siri is vastly more capable than ever before.
For a more complete breakdown of all the new features and changes, check out our iOS 27 guide.
Beta 4 brings the following changes, in addition to bug fixes and performance improvements:
- There are two additional Siri voices that work with the pace and expressivity sliders. There are others still listed as “coming soon.”
- There’s a new Siri pop-up window when you activate it by swiping down on the home screen.
