# invalidateIntrinsicContentSize()

Invalidates the view’s intrinsic content size.

## Declaration

```swift
func invalidateIntrinsicContentSize()
```

## Discussion

Discussion Call this when something changes in your custom view that invalidates its intrinsic content size. This allows the constraint-based layout system to take the new intrinsic content size into account in its next layout pass.
