WWDC26: Extend Reality Composer Pro 3 functionality with Xcode | Apple
Apple's Reality Composer Pro 3 lets developers build Xcode plug-ins exposing custom components to artists in-editor.
“artists can change the water level or the rotation speed and see the cauldron react in real time, without having to build and deploy an app”
Apple previewed Reality Composer Pro 3 at WWDC26, adding the ability to build Xcode plug-ins that expose custom Swift components and Script Graph nodes to artists directly in the editor. It's a 3D/spatial content-authoring tooling update with no meaningful AI signal, so it's of limited relevance to an AI industry newsletter.
