Apple:

Apple today announced the availability of new software tools and technologies that enable developers to create groundbreaking app experiences for Apple Vision Pro — Apple’s first spatial computer.

[…]

With the visionOS SDK, developers can utilize the powerful and unique capabilities of Vision Pro and visionOS to design brand-new app experiences across a variety of categories including productivity, design, gaming, and more.

This is all a part of Xcode 15 which you can download today.

Playing around with the visionOS simulator is fascinating. It already exposes a lot of the final operating system—including first party applications and design elements—that I hadn’t previously seen elsewhere.

The new Reality Composer Pro application is also more powerful than I would have expected. It feels like a stripped down version of Unity3D. I hope Apple continues development on it. I would love to see it eventually become a full-fledged 3D development environment.
