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.

  • Undocumented

    Declaration

    Swift

    let value: Any

  • Undocumented

    Declaration

    Swift

    init<T>(_ value: T?)

  • Returns a Boolean value indicating whether two values are equal.

    Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false.

    Declaration

    Swift

    static func == (lhs: AnyCodable, rhs: AnyCodable) -> Bool

    Parameters

    lhs

    A value to compare.
    rhs

    Another value to compare.

  • A textual representation of this instance.

    Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the String(describing:) initializer. This initializer works with any type, and uses the custom description property for types that conform to CustomStringConvertible:

    struct Point: CustomStringConvertible {
    let x: Int, y: Int

    var description: String {
        return "(\(x), \(y))"
    }
}

let p = Point(x: 21, y: 30)
let s = String(describing: p)
print(s)
// Prints "(21, 30)"

    The conversion of p to a string in the assignment to s uses the Point type’s description property.

    Declaration

    Swift

    var description: String { get }

  • A textual representation of this instance, suitable for debugging.

    Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the String(reflecting:) initializer. This initializer works with any type, and uses the custom debugDescription property for types that conform to CustomDebugStringConvertible:

    struct Point: CustomDebugStringConvertible {
    let x: Int, y: Int

    var debugDescription: String {
        return "(\(x), \(y))"
    }
}

let p = Point(x: 21, y: 30)
let s = String(reflecting: p)
print(s)
// Prints "(21, 30)"

    The conversion of p to a string in the assignment to s uses the Point type’s debugDescription property.

    Declaration

    Swift

    var debugDescription: String { get }

  • Hashes the essential components of this value by feeding them into the given hasher.

    Implement this method to conform to the Hashable protocol. The components used for hashing must be the same as the components compared in your type’s == operator implementation. Call hasher.combine(_:) with each of these components.

    Important

    In your implementation of hash(into:), don’t call finalize() on the hasher instance provided, or replace it with a different instance. Doing so may become a compile-time error in the future.

    Declaration

    Swift

    func hash(into hasher: inout Hasher)
