# exported(as:)

Using the type’s Transferable conformance implementation, exports a value as binary data.

## Declaration

```swift
func exported(as contentType: UTType?) async throws -> Data
```

## Parameters

- `contentType`: A content type of the returned data. If no content type is provided, CoreTransferable generates data using the first TransferRepresentation in the Transferable conformance that supports export.

## Discussion

Discussion If the Transferable is backed by a file URL, this might cause loading the entire file contents into memory. This function uses the first representation that conforms to the given content type in static var transferRepresentation requirement of the Transferable protocol or in the var body property of a custom TransferRepresentation. The default implementation of this function is available to all types that conform to Transferable protocol.
