Extend Reality Composer Pro 3 functionality with Xcode

A Podkey summary of Extend Reality Composer Pro 3 functionality with Xcode, from WWDC 2026.Today’s thread is all about turning Reality Composer Pro from a nice editor into something much closer to a custom toolbench. The big idea is that developers can plug in their own components, systems, shader controls, animation actions, and even Script Graph nodes, so artists and designers can work directly in the editor instead of bouncing back and forth to app builds. And underneath all that, there are some very practical wins too, like better git merges for Reality files and the ability to debug your plugin code live inside the editor.The plugin architectureCustom components that artists can actually editSystems that turn values into live feedbackDriving Shader Graph parameters from SwiftCustom actions in the sequencerScript Graph nodes from a macroTeam workflow and version controlDebugging live inside the editorThis podcast was created with Podkey.
