# assetContentChanged

A Boolean value that indicates whether the asset’s photo or video content has changed.

```
var assetContentChanged: Bool { get }
```

## Discussion

If this value `true`, you can use the [`PHImageManager`](/documentation/Photos/PHImageManager) class to retrieve updated content.

This value is `false` if the asset has not changed or if the change details do not refer to a [`PHAsset`](/documentation/Photos/PHAsset) object.
