# savingFileType

Returns the file type to use for saving a document.

## Declaration

```swift
var savingFileType: String? { get }
```

## Return Value

Return Value A Uniform Type Identifier (UTI) identifying a document type (for example, PDF or HTML).

## Discussion

Discussion The default implementation returns the current file type obtained from the fileType property. The default implementation of the save(to:for:completionHandler:) method appends an extension to the file URL that’s based on the file type. So if you want to move the document to a new type and extension, you can override this method to supply that file type.
