Hi All,
There is a new version of HelloWord at https://developer.apple.com/documentation/visionOS/World
All those problems listed before are from the first version from June 16 2023. The new version is from July 14 2023. It compiles with no problems and run at the simulator also with no problems.
Download it and enjoy.
BTW, that's a fantastic app!
Xcode 15.0 beta 5 (15A5209g) macOS Sonoma 14.0 Beta (23A5301g) Mac mini 2018 16gB RAM (Intel processor)
