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)
