# IndexSet.RangeView

A view of the contents of an IndexSet, organized by range.

## Declaration

```swift
struct RangeView
```

## Overview

Overview For example, if an IndexSet is composed of: [1..<5] and [7..<10] and [13] then calling next() on this view’s iterator will produce 3 ranges before returning nil.
