This MachOFile.cpp contains an upload log to the App Store, in which there were multiple words 'realityOS', it is an OS different from macOS and iOS, and a simulator for developers is also included. That's what developer Steve Trafton-Smith discovered.

Apple is said to have been developing VR-related technology since around 2016, and it is reported that it will start developing VR / AR headsets in 2019. The VR / AR headset has 'performance equivalent to the M1 Pro and is expected to be released in 2022,' said Mark Gurman, a Bloomberg reporter known as a leaker related to Apple products.

It was rumored that a dedicated OS was also developed independently with the development of VR / AR headset, but this discovery confirmed the development of reality OS, Apple Insider of Apple related news site commented I am. Apple's own VR / AR headset is expected to be announced in late 2022, but Apple Insider points out that it may be postponed after 2023 given the impact of the recent semiconductor shortage.
