VisionOS

visionOS is an operating system developed by Apple for its Vision Pro augmented reality headset. Both were announced on June 5 at the 2023 Worldwide Developers Conference.

Development history
realityOS had previously been identified as an internal project at Apple Inc. It was believed to be in development to provide an operating system for an as-yet unannounced AR / VR device.

Work on a project known as "rOS" for a forthcoming headset codenamed T288 had been reported as early as November 2017, after ARKit had been publicly released with iOS 11. An early headset prototype was based on existing iPhone components. The continued existence of the project had been revealed again in February 2022 with references to "realityOS" discovered in App Store upload logs. It had also been discovered in open source code posted to by Apple.
