# NSFileProviderItemVersion

The version of the item’s content and its metadata.

## Declaration

```swift
class NSFileProviderItemVersion

## Overview

Overview Each item has a separate version object for its metadata and its content. As a result, the file provider can update an item’s metadata without uploading or downloading a new copy of its content.
