Readium Swift Toolkit

Readium Mobile is a toolkit for ebooks, audiobooks and comics written in Swift & Kotlin.

This toolkit is a modular project, which follows the Readium Architecture.

A Test App demonstrates how to integrate the Readium Swift toolkit in your own reading app

Using Readium

Readium libraries are distributed with Swift Package Manager (recommended), Carthage and CocoaPods. It’s also possible to clone the repository (or a fork) and depend on the libraries locally.

The Test App contains examples on how to use all these dependency managers.

Swift Package Manager

From Xcode, open File > Add Packages and use Readium’s GitHub repository for the package URL:

You are then free to add one or more Readium libraries to your application. They are designed to work independently.

If you’re stuck, find more information at


Add the following to your Cartfile:

github "readium/swift-toolkit" ~> 2.2.0

Then, follow the usual Carthage steps to add the Readium libraries to your project.

Note that Carthage will build all Readium modules and their dependencies, but you are free to add only the ones you are actually using. The Readium libraries are designed to work independently.

Refer to the following table to know which dependencies are required for each Readium library.

R2Shared R2Streamer R2Navigator ReadiumOPDS ReadiumLCP
R2Shared ✔️ ✔️ ✔️ ✔️
CryptoSwift ✔️ ✔️
DifferenceKit ✔️
Fuzi ✔️ ✔️ ✔️ ✔️ ✔️
GCDWebServer ✔️
Minizip ✔️ ✔️ ✔️ ✔️ ✔️
SQLite.swift ✔️
SwiftSoup ✔️ ✔️ ✔️ ✔️ ✔️
ZIPFoundation ✔️


Add the following pod statements to your Podfile for the Readium libraries you want to use:

pod 'R2Shared', podspec: ''
pod 'R2Streamer', podspec: ''
pod 'R2Navigator', podspec: ''
pod 'ReadiumOPDS', podspec: ''
pod 'ReadiumLCP', podspec: ''

Take a look at CocoaPods’s documentation for more information.

Local Git Clone

You may prefer to use a local Git clone if you want to contribute to Readium, or if you are using your own fork.

First, add the repository as a Git submodule of your app repository, then checkout the desired branch or tag:

git submodule add

Next, drag and drop the whole swift-toolkit folder into your project to import Readium as a Swift Package.

Finally, add the Readium libraries you want to use to your app target from the General tab, section Frameworks, Libraries, and Embedded Content.

Building with Readium LCP

Using the toolkit with Readium LCP requires additional dependencies, including the framework R2LCPClient.framework provided by EDRLab. Contact EDRLab to request your private R2LCPClient.framework and the setup instructions.
