# trackingObjects

Objects to track in the scene.

```
var trackingObjects: Set<ARReferenceObject> { get set }
```

## Discussion

The system tracks the object at the full frame rate of the selected `videoFormat`. When an object is tracked, an
`ARObjectAnchor` is added to the session.

Use this property for moving or handheld objects that require precise, per-frame pose updates. High frame-rate tracking
significantly increases power consumption and processing load. For mostly stationary objects, use `detectionObjects`
instead.

> Note: Only the `.referenceobject` format (introduced in iOS 27) is supported; the older `.arobject` format works only
> with `detectionObjects`. A single session can’t use both formats.
