# TransferRepresentationBuilder Creates a transfer representation by composing existing transfer representations. ``` @resultBuilder struct TransferRepresentationBuilder where Item : Transferable ``` ## Topics ### Building a transfer representation [`static func buildBlock(Content) -> Content`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:)) Passes a single transfer representation to the builder unmodified. [`static func buildExpression(R) -> R`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildExpression(_:)-3z8sl) Builds a transfer representation from an expression. [`static func buildExpression(CodableRepresentation) -> CodableRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildExpression(_:)-6qtdp) Builds an encodable and decodable transfer representation from an expression. ### Combining transfer representations [`static func buildBlock(C1, C2) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:)) Combines multiple transfer representations into a single transfer representation. [`static func buildBlock(C1, C2, C3) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:_:)) Combines multiple transfer representations into a single transfer representation. [`static func buildBlock(C1, C2, C3, C4) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:_:_:)) Combines multiple transfer representations into a single transfer representation. [`static func buildBlock(C1, C2, C3, C4, C5) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:_:_:_:)) Combines multiple transfer representations into a single transfer representation. [`static func buildBlock(C1, C2, C3, C4, C5, C6) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:_:_:_:_:)) Combines multiple transfer representations into a single transfer representation. [`static func buildBlock(C1, C2, C3, C4, C5, C6, C7) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:_:_:_:_:_:)) Combines multiple transfer representations into a single transfer representation. [`static func buildBlock(C1, C2, C3, C4, C5, C6, C7, C8) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:_:_:_:_:_:_:)) Combines multiple transfer representations into a single transfer representation. [`static func buildBlock(C1, C2, C3, C4, C5, C6, C7, C8, C9) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:_:_:_:_:_:_:_:)) Combines multiple transfer representations into a single transfer representation. [`static func buildBlock(C1, C2, C3, C4, C5, C6, C7, C8, C9, C10) -> TupleTransferRepresentation`](/documentation/CoreTransferable/TransferRepresentationBuilder/buildBlock(_:_:_:_:_:_:_:_:_:_:)) Combines multiple transfer representations into a single transfer representation. --- Copyright © 2026 Apple Inc.
