# minimumInteritemSpacing

The minimum spacing (in points) to use between items in the same row or column.

## Declaration

```swift
var minimumInteritemSpacing: CGFloat { get set }
```

## Discussion

Discussion If the delegate does not implement the collectionView(_:layout:minimumInteritemSpacingForSectionAt:) method, the flow layout object uses the value of this property to set the spacing between items in the same line. For a vertically scrolling layout, the value represents the minimum spacing between items in the same row. For a horizontally scrolling layout, the value represents the minimum spacing between items in the same column. The layout object uses this spacing only to compute how many items can fit in a single row or column. The actual spacing may be increased after the number of items has been determined, as illustrated in Figure 1.

The default value of this property is 10.0.
