# URL.Template.Value The value of a variable used for expanding a template. ``` struct Value ``` ## Overview A value can either be some text, a list, or an associate list (a dictionary). ### Examples ```swift let hello: URL.Template.Value = .text("Hello World!") let list: URL.Template.Value = .list(["red", "green", "blue"]) let keys: URL.Template.Value = .associativeList([ "semi": ";", "dot": ".", "comma": ",", ]) ``` Alternatively, for constants, the `ExpressibleBy…Literal` implementations can be used, i.e. ```swift let hello: URL.Template.Value = "Hello World!" let list: URL.Template.Value = ["red", "green", "blue"] let keys: URL.Template.Value = [ "semi": ";", "dot": ".", "comma": ",", ] ``` ## Topics ### Type Methods [`static func associativeList(some Sequence<(key: String, value: String)>) -> URL.Template.Value`](/documentation/Foundation/URL/Template/Value/associativeList(_:)) An associative list value (ordered key-value pairs) to be used with a `URL.Template`. [`static func list(some Sequence) -> URL.Template.Value`](/documentation/Foundation/URL/Template/Value/list(_:)) A list value (an array of `String`s) to be used with a `URL.Template`. [`static func text(String) -> URL.Template.Value`](/documentation/Foundation/URL/Template/Value/text(_:)) A text value to be used with a `URL.Template`. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`ExpressibleByUnicodeScalarLiteral`](/documentation/Swift/ExpressibleByUnicodeScalarLiteral) [`Copyable`](/documentation/Swift/Copyable) [`ExpressibleByArrayLiteral`](/documentation/Swift/ExpressibleByArrayLiteral) [`Escapable`](/documentation/Swift/Escapable) [`CustomStringConvertible`](/documentation/Swift/CustomStringConvertible) [`ExpressibleByStringLiteral`](/documentation/Swift/ExpressibleByStringLiteral) [`ExpressibleByExtendedGraphemeClusterLiteral`](/documentation/Swift/ExpressibleByExtendedGraphemeClusterLiteral) [`Equatable`](/documentation/Swift/Equatable) [`Hashable`](/documentation/Swift/Hashable) [`Sendable`](/documentation/Swift/Sendable) [`ExpressibleByDictionaryLiteral`](/documentation/Swift/ExpressibleByDictionaryLiteral) --- Copyright © 2026 Apple Inc.
