# leading

The leftmost or rightmost gravity area in a horizontally oriented stack view, based on the user interface language or the explicitly set user interface layout direction.

## Declaration

```swift
static var leading: NSStackView.Gravity { get }
```

## Discussion

Discussion For a left to right layout direction, the leading gravity area is on the left. Use only when the value of the orientation property is NSUserInterfaceLayoutOrientation.horizontal.
