# minimumInteritemSpacing

The minimum spacing to use between items in the same row.

## Declaration

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

## Discussion

Discussion If the delegate object does not implement the collectionView(_:layout:minimumInteritemSpacingForSectionAt:) method, the flow layout uses the value in this property to set the spacing between items in the same line. For a vertically scrolling grid, this value represents the minimum spacing between items in the same row. For a horizontally scrolling grid, this value represents the minimum spacing between items in the same column. This spacing is used to compute how many items can fit in a single line, but after the number of items is determined, the actual spacing may possibly be adjusted upward. The default value of this property is 10.0.
