# fetchAssetCollections(with:subtype:options:)

Retrieves asset collections of the specified type and subtype.

```
class func fetchAssetCollections(with type: PHAssetCollectionType, subtype: PHAssetCollectionSubtype, options: PHFetchOptions?) -> PHFetchResult<PHAssetCollection>
```

## Parameters

`type`

A type of asset collection, such as an album or a moment. See [`PHAssetCollectionType`](/documentation/Photos/PHAssetCollectionType).

`subtype`

A subtype of asset collection. See [`PHAssetCollectionSubtype`](/documentation/Photos/PHAssetCollectionSubtype).

`options`

Options that specify a filter predicate and sort order for the fetched asset collections, or `nil` to use default options. For details, see [`PHFetchOptions`](/documentation/Photos/PHFetchOptions).

## Return Value

A fetch result that contains the requested [`PHAssetCollection`](/documentation/Photos/PHAssetCollection) objects, or an empty fetch result if no objects match the request.

## Discussion

By default, the returned [`PHFetchResult`](/documentation/Photos/PHFetchResult) object contains all asset collections with the specified type and subtype. To retrieve a more specific set of asset collections, provide a [`PHFetchOptions`](/documentation/Photos/PHFetchOptions) object containing a filter predicate.
