# TransferRepresentation

A declarative description of the process of importing and exporting a transferable item.

## Declaration

```swift
protocol TransferRepresentation<Item> : Sendable
```

## Overview

Overview Combine multiple existing transfer representations to compose a single transfer representation that describes how to transfer an item in multiple scenarios. The following shows a Greeting type that transfers both as a Codable type and by proxy through its message string. import UniformTypeIdentifiers

struct Greeting: Codable, Transferable {     let message: String     var displayInAllCaps: Bool = false

static var transferRepresentation: some TransferRepresentation {         CodableRepresentation(contentType: .greeting)         ProxyRepresentation(exporting: \.message)     } }

extension UTType {     static let greeting = UTType(exportedAs: "com.example.greeting") }
