# RemoteCallArgument Represents an argument passed to a distributed call target. ``` struct RemoteCallArgument ``` ## Topics ### Initializers [`init(label: String?, name: String, value: Value)`](/documentation/Distributed/RemoteCallArgument/init(label:name:value:)) ### Instance Properties [`var effectiveLabel: String`](/documentation/Distributed/RemoteCallArgument/effectiveLabel) The effective label of this argument. This reflects the semantics of call sites of function declarations without explicit label definitions in Swift. [`let label: String?`](/documentation/Distributed/RemoteCallArgument/label) The “argument label” of the argument. The label is the name visible name used in external calls made to this target, e.g. for `func hello(label name: String)` it is `label`. [`let name: String`](/documentation/Distributed/RemoteCallArgument/name) The internal name of parameter this argument is accessible as in the function body. It is not part of the functions API and may change without breaking the target identifier. [`let value: Value`](/documentation/Distributed/RemoteCallArgument/value) The value of the argument being passed to the call. As `RemoteCallArgument` is always used in conjunction with `recordArgument` and populated by the compiler, this Value will generally conform to a distributed actor system’s `SerializationRequirement`. --- Copyright © 2026 Apple Inc.
