# NSStackView.VisibilityPriority

The various Auto Layout priorities for a view in the stack view to remain attached.

## Declaration

```swift
struct VisibilityPriority
```

## Discussion

Discussion For an explanation of how visibility priority interacts with clipping resistance to determine the detachment behavior of a stack view’s views, see the discussions for the setClippingResistancePriority(_:for:) and setVisibilityPriority(_:for:) methods. A view in a detached state is not present in the stack view’s view hierarchy, but it still consumes memory.
