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.

Installation

Swift Package Manager

Add the AnyCodable package to your target dependencies in Package.swift:

import PackageDescription

let package = Package(
  name: "YourProject",
  dependencies: [
    .package(
        url: "https://github.com/Flight-School/AnyCodable",
        from: "0.4.0"
    ),
  ]
)

Then run the swift build command to build your project.

CocoaPods

You can install AnyCodable via CocoaPods by adding the following line to your Podfile:

pod 'AnyCodable-FlightSchool', '~> 0.4.0'

Run the pod install command to download the library and integrate it into your Xcode project.

Note The module name for this library is "AnyCodable" --- that is, to use it, you add import AnyCodable to the top of your Swift code just as you would by any other installation method. The pod is called "AnyCodable-FlightSchool" because there's an existing pod with the name "AnyCodable".

Carthage

To use AnyCodable in your Xcode project using Carthage, specify it in Cartfile:

github "Flight-School/AnyCodable" ~> 0.4.0

Then run the carthage update command to build the framework, and drag the built AnyCodable.framework into your Xcode project.

Usage

AnyEncodable

import AnyCodable

let dictionary: [String: AnyEncodable] = [
    "boolean": true,
    "integer": 1,
    "double": 3.141592653589793,
    "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": 3.141592653589793,
         "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.
