Type-erased wrappers for Encodable, Decodable, and Codable values

AnyCodable

Type-erased wrappers for Encodable, Decodable, and Codable values.

This functionality is discussed in Chapter 3 of Flight School Guide to Swift Codable.

AnyEncodable

import AnyCodable

let dictionary: [String: AnyEncodable] = [
    "boolean": true,
    "integer": 1,
    "double": 3.14159265358979323846,
    "string": "string",
    "array": [1, 2, 3],
    "nested": [
        "a": "alpha",
        "b": "bravo",
        "c": "charlie"
    ]
]

let encoder = JSONEncoder()
let json = try! encoder.encode(dictionary)

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: AnyDecodable].self, from: json)

AnyCodable

AnyCodable can be used to wrap values for encoding and decoding.
