AnyDecodable Structure Reference

public struct AnyDecodable : Decodable

extension AnyDecodable: CustomStringConvertible

extension AnyDecodable: CustomDebugStringConvertible

A type-erased Decodable value.

The AnyDecodable type forwards decoding responsibilities to an underlying value, hiding its specific underlying type.

You can decode mixed-type values in dictionaries and other collections that require Decodable conformance by declaring their contained type to be AnyDecodable:

let json = “”“ { "boolean”: true, “integer”: 1, “double”: 3.14159265358979323846, “string”: “string”, “array”: [1, 2, 3], “nested”: { “a”: “alpha”, “b”: “bravo”, “c”: “charlie” } } “”“.data(using: .utf8)!

let decoder = JSONDecoder() let dictionary = try! decoder.decode([String: AnyCodable].self, from: json)

value
The wrapped value of any type.

Swift
