MessagePack

A MessagePack encoder and decoder for Codable types.

This functionality is discussed in Chapter 7 of Flight School Guide to Swift Codable.

Requirements

• Swift 4.2+

Usage

Encoding Messages

import MessagePack

let encoder = MessagePackEncoder()
let value = try! encoder.encode(["a": 1, "b": 2, "c": 3])
// [0x83, 0xA1, 0x62, 0x02, 0xA1, 0x61, 0x01, 0xA1, 0x63, 0x03]

Decoding Messages

import MessagePack

let decoder = MessagePackDecoder()
let data = Data(bytes: [0xCB, 0x40, 0x09, 0x21, 0xF9, 0xF0, 0x1B, 0x86, 0x6E])
let value = try! decoder.decode(Double.self, from: data)
// 3.14159

Installation

Swift Package Manager

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

import PackageDescription

let package = Package(
  name: "YourProject",
  dependencies: [
    .package(
        url: "https://github.com/Flight-School/MessagePack",
        from: "1.2.3"
    ),
  ]
)

Then run the swift build command to build your project.

CocoaPods

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

pod 'MessagePack-FlightSchool', '~> 1.2.4'

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

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