# transform(in:)

The container view’s 3D transform converted to a defined coordinate space.

## Declaration

```swift
func transform(in coordinateSpace: some CoordinateSpaceProtocol) -> AffineTransform3D?
```

## Discussion

Discussion If the view doesn’t have a well-defined transform, such as if it’s affected by a projection transform, this function may return nil.
