# Entity.CoordinateSpaceReference

Defines the coordinate space reference for transform conversion.

## Declaration

```swift
enum CoordinateSpaceReference
```

## Overview

Overview Entity uses this option as a reference coordinate space during transform conversion. Depending on the coordinate space that a caller entity is parented under, and whether there is an immersive space open, some transform conversion case can be inapplicable. Check out each case for more information.
