# holdingPriority

The priority for a split view item to hold its size.

## Declaration

```swift
var holdingPriority: NSLayoutConstraint.Priority { get set }
```

## Discussion

Discussion This priority affects the split view item’s width (for a vertical split view) or height (for a horizontal split view). The view with the lowest priority is the first to gain additional width if the split view grows or shrinks. The default of this property is defaultLow.
