# intrinsicContentSize

The hosting controller’s view automatically invalidate its intrinsic content size when its ideal size changes.

## Declaration

```swift
static let intrinsicContentSize: UIHostingControllerSizingOptions
```

## Discussion

Discussion Use this option when the hosting controller’s view is being laid out with Auto Layout. note: This option comes with a performance cost because it asks for the ideal size of the content using the unspecified size proposal.
