# Dispatch Work Item

The work you want to perform, encapsulated in a way that lets you attach a completion handle or execution dependencies.

## Overview

Overview A dispatch work item encapsulates work to be performed on a dispatch queue or within a dispatch group. You can also use a work item as a dispatch source event, registration, or cancellation handler.
