# NSArrayController

A bindings-compatible controller that manages a collection of objects.

## Declaration

```swift
class NSArrayController
```

## Overview

Overview Typically the collection that an NSArrayController manages is an array, however, if the controller manages a relationship of a managed object (see NSManagedObject) the collection may be a set. NSArrayController provides selection management and sorting capabilities.
