# ProgressReporting

An interface for objects that report progress using a single progress instance.

```
protocol ProgressReporting : NSObjectProtocol
```

## Overview

Create the returned progress object using [`ProgressReporting`](/documentation/Foundation/ProgressReporting). The resulting object has no parent allowing the caller to add it to a progress tree using [`ProgressReporting`](/documentation/Foundation/ProgressReporting).

You can return a single progress object or a progress tree. If you are creating a progress tree, add the children to the returned progress object as described in [`Reporting Progress for Multiple Operations`](/documentation/Foundation/Progress#Reporting-Progress-for-Multiple-Operations).

You are responsible for setting and updating the [`ProgressReporting`](/documentation/Foundation/ProgressReporting) of any [`Progress`](/documentation/Foundation/Progress) object you create.
