# infinity

A size proposal that contains infinity in both dimensions.

## Declaration

```swift
static let infinity: ProposedViewSize
```

## Discussion

Discussion Both dimensions contain doc://com.apple.documentation/documentation/CoreFoundation/CGFloat/1454161-infinity in this size proposal. Subviews of a custom layout return their maximum size when you propose this value using the dimensions(in:) method. A custom layout should also return its maximum size from the sizeThatFits(proposal:subviews:cache:) method for this value.
