To build an interactive AR companion in RealityKit, implement ECS architecture for companion behavior, use body and hand tracking for gesture reactions, and apply state machines or behavior trees to drive responsive, lifelike character motions and interactions.

The best way to manage AR companion state persistence across iOS sessions is integrating scene lifecycle management and AR anchoring, which enables virtual characters to preserve their state and maintain real-world persistence between interactions.

Yes, you can use RealityKit ECS architecture to model AI-driven character behavior on visionOS by implementing utility AI patterns, behavior trees, and state machines that process entity components to generate responsive and believable companion reactions.

Body and hand tracking in RealityKit captures physical user motions and maps them onto skeletal rigs and facial morph targets, enabling procedural motions and lifelike character animation for interactive AR companions.

Yes, you need Apple RealityKit and ARKit integrations to implement spatial audio, AR anchoring, and entity lifecycle management, ensuring robust environment interaction and real-world persistence for virtual characters.

To anchor a virtual character to a detected horizontal plane in an iOS AR app, initialize RealityKit, detect the plane using ARKit, and attach the companion entity to the plane anchor to ensure it interacts accurately with the physical space.
