# itemVersion

A version object that tracks changes to an item.

## Declaration

```swift
optional var itemVersion: NSFileProviderItemVersion { get }
```

## Discussion

Discussion The version object lets you track changes to an item’s content and metadata separately. Updating the version also invalidates the thumbnail cache. For more information, see NSFileProviderItemVersion.
