The software development kit (SDK) for Apple Vision Pro has been released for developers, alongside new betas for iOS 17, iPadOS 17, macOS Sonoma, watchOS 10, and tvOS 17, and I've been using visionOS on my Mac since it came out.
For those unaware, Apple has an app called Xcode, which allows you to create apps for all of its platforms. On June 21, a beta of it was released that came with visionOS' SDK, and you can load up a 'Simulator', which creates an environment where you can try out Vision Pro's operating system.
