# transform

A matrix encoding the position, orientation, and scale of the anchor relative to the world coordinate space of the AR session the anchor is placed in.

```
var transform: simd_float4x4 { get }
```

## Discussion

World coordinate space in ARKit always follows a right-handed convention, but is oriented based on the session configuration. For details, see [Understanding World Tracking](/documentation/ARKit/understanding-world-tracking).
