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: "0.6.0"
),
]
)
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', '~> 0.6.0'
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" ~> 0.6.0
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"
],
"null": nil
]
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"
},
"null": null
}
""".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.
