Apple has released the third developer beta of iOS 27, marking a key milestone in its summer software testing cycle. The update replaces beta 2 and is expected to include major enhancements to Siri's AI capabilities ahead of a public launch this fall.
The company also rolled out beta 3 for iPadOS 27, tvOS 27, and visionOS 27, expanding the testing to its broader ecosystem of devices. These releases continue Apple's annual pattern of iterative refinements leading up to a mass-market rollout.
While iOS 27 dominates developer attention, Apple is still preparing iOS 26.6 as the next iPhone update, having released its fourth developer beta. That version has been in testing since late May, suggesting Apple is maintaining parallel tracks for both current and upcoming OS generations.
Developers are now installing the new betas to probe for performance improvements, bug fixes, and new features. The Siri upgrade, in particular, could reshape how users interact with iPhones and iPads if it proves stable.
Some analysts caution that early betas often contain bugs or incomplete features, meaning the final consumer release may differ significantly from what developers see today.
