Structures

A type-erased Codable value.

The AnyCodable type forwards encoding and decoding responsibilities to an underlying value, hiding its specific underlying type.

You can encode or decode mixed-type values in dictionaries and other collections that require Encodable or Decodable conformance by declaring their contained type to be AnyCodable.

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)

A type-erased Encodable value.

The AnyEncodable type forwards encoding responsibilities to an underlying value, hiding its specific underlying type.

You can encode mixed-type values in dictionaries and other collections that require Encodable conformance by declaring their contained type to be AnyEncodable:

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)

An error type for keychain operations.

A struct representation of a generic password item in the keychain.

The keychain query uses generic password for the item’s class, the serviceName property for the item’s service, and the account property for the item’s account name.

Struct representing a multipart attachment to a multipart form data request
