Apple has begun rolling out the visionOS 27 developer beta 1.
The beta arrived just hours after the WWDC26 keynote where Apple previewed the new OS. It is distributed through the Apple Developer portal and targets the latest Vision Pro units. The build includes the promised spatial UI tweaks, a refreshed Home environment, and early access to the new SwiftUI‑based rendering pipeline. Developers can download it now and start compiling their existing apps against the new SDK.
Getting the beta matters because it gives app makers time to adapt to the updated APIs before the public launch later this year. Early adoption also lets Apple collect performance data and squash bugs that could affect the consumer experience.
As with every Apple beta, expect a handful of crashes and missing features—nothing that will halt serious development, but enough to keep you humble.
