# CFBitVector

## Declaration

```swift
class CFBitVector
```

## Overview

Overview CFBitVector and its derived mutable type, CFMutableBitVector, manage ordered collections of bit values, which are either 0 or 1. CFBitVector creates static bit vectors and CFMutableBitVector creates dynamic bit vectors.
