Following WWDC 2026, Apple has seeded the first developer betas for six major operating systems: iOS 27, iPadOS 27, macOS 27, watchOS 27, tvOS 27, and visionOS 27. Registered developers can opt in to test these releases through the Settings app on each device. The software includes many features shown during Apple's keynote, though not all demoed features are available immediately.

Key highlights include an updated Siri with a dedicated app and new AI capabilities for applications like Photos, Camera, and Wallet. The releases contain dozens of new features alongside hundreds of smaller tweaks and improvements. Apple plans to release a public beta in July, allowing general users to test the software before the official public launch.

All six operating systems will launch to the public this fall. The developer betas serve as the first testing phase for Apple's latest software updates, giving developers time to incorporate new features into their applications. Apple has not specified exact release dates for either the public beta or the final versions.
