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


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:

2.2.0 ">
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.

  • Implement Pop-Up Noterefs

    Implement Pop-Up Noterefs

    The r2-navigator-kotlin has a click handler that is bridged from JS that checks for <a epub:type="noteref"> and displays the target content in a modal.

    Relevant code:=

    var handleClick = function(event) {


    fun handleClick(html: String) {
        val doc = Jsoup.parse(html)
        val link ="a[epub:type=noteref]")?.first()
        link?.let { noteref ->
            val href = noteref.attr("href")
            if (href.indexOf("#") > 0) {
                val id = href.substring(href.indexOf('#') + 1)
                var absolute = getAbsolute(href, resourceUrl!!)
                absolute = absolute.substring(0, absolute.indexOf("#"))
                val document = Jsoup.connect(absolute).get()
                val aside ="aside#$id").first()?.html()
                aside?.let {
                    val safe = Jsoup.clean(aside, Whitelist.relaxed())
                    // Initialize a new instance of LayoutInflater service
                    val inflater = activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
                    // Inflate the custom layout/view
                    val customView = inflater.inflate(R.layout.popup_footnote, null)
                    // Initialize a new instance of popup window
                    val mPopupWindow = PopupWindow(
                    mPopupWindow.isOutsideTouchable = true
                    mPopupWindow.isFocusable = true
                    // Set an elevation value for popup window
                    // Call requires API level 21
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                        mPopupWindow.elevation = 5.0f
                    val textView = customView.findViewById( as TextView
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                        textView.text = Html.fromHtml(safe, Html.FROM_HTML_MODE_COMPACT)
                    } else {
                        textView.text = Html.fromHtml(safe)
                    // Get a reference for the custom view close button
                    val closeButton = customView.findViewById( as ImageButton
                    // Set a click listener for the popup window close button
                    closeButton.setOnClickListener {
                        // Dismiss the popup window
                    // Finally, show the popup window at the center location of root relative layout
                    mPopupWindow.showAtLocation(this, Gravity.CENTER, 0, 0)
                    overrideUrlLoading = false

    The same could be implemented for iOS.

    Current click handling:

    function onClick(event) {
      if (event.defaultPrevented || isInteractiveElement( {
      if (!window.getSelection().isCollapsed) {
        // There's an on-going selection, the tap will dismiss it so we don't forward it.
        "screenX": event.screenX,
        "screenY": event.screenY,
        "clientX": event.clientX,
        "clientY": event.clientY,

    In terms of implementation, I'll start with comparing to the Android version.

    In reading through the behavior, it appears that all taps (on any element) call the Kotlin function before the event is propagated through the DOM. The Kotlin checks to see if the tapped element is a[epub:type=noteref] and if so, identifies the target material. It's important to do this in the host code, rather than JS, so that you can access whatever file is being targeted. If the Kotlin func successfully displays the modal, it does a little semaphore action (so to speak) to the WebView delegate to cancel the navigation. (That last bit is a little convoluted since shouldOverrideUrlLoading appears to be employed in reverse, but that's what I gather.)

    In contrast, the iOS click handler explicitly avoids calling across the JS bridge to Swift for any interactive elements, including <a> tags. The recursive isInteractiveElement JS function references this regarding don't-mess-up-the-author's-scripts.


    This test contains 3 links with different behaviors:

    1. normal link, which should take the user to the previous test;
    2. scripted link, which should display a hidden element below the second paragraph;
    3. scripted link, which is using window.location to send the user to the next test.

    The test is here and looks like:

    <a href="../Text/test-005.xhtml">I’m a simple link to the previous chapter (Audio controls with buttons)</a>
    <a id="anchor-hook" href="#note">I’m a link which will be used to display something below this paragraph</a>
    <a id="anchor-programmatic" href="#anchor-programmatic">I’m a link using window.location to the next chapter (DOM Storage)</a>

    along with

    var hook = document.getElementById("anchor-hook"),
        prog = document.getElementById("anchor-programmatic"),
        note = document.getElementById("note");
    hook.addEventListener("click", function(e) {
      if ( === "none") { = "block";
      } else { = "none";
    }, false);
    prog.addEventListener("click", function(e) {
      window.location = "../Text/test-007.xhtml";
    }, false);

    I am tempted to check for epub:type=noteref in the JS and call a new, special Swift handler specifically for this purpose. I think that links of that type should be handled by the app and any user scripts are forfeit.

    The other question in my mind is what to do on the targeted content, because typically (in my understanding of things) it should be hidden. Not sure if the author should have to display:none it or if that should be part of the styles injected by the app...I lean towards the latter.

    I intend to do this work over the next day or two, but I wanted to ask for feedback before my PR leaps full-armed from the brow of Jove.

  • Should we raise the minimum supported iOS version to iOS 10?

    Should we raise the minimum supported iOS version to iOS 10?

    EDIT: We talked about this issue on the last dev meeting, and agreed on dropping support for iOS 9. Unfortunately, we don't have the resources to maintain the toolkit on such older versions. Apple is not making it easy.

    The next tagged release will be the last one supporting iOS 9.

    I'm testing the waters.

    Right now, Readium supports down to iOS 9, but:

    • the PDF navigator requires iOS 11
    • the audiobook navigator will require iOS 10

    Personally, I think it's time to raise the minimum requirement to iOS 10.

    3.3% of iPads are < iOS 10, and only 0.1% on iPhones.

    Any disagreement?

  • Support for Swift Package Manager

    Support for Swift Package Manager

    Xcode 11 finally brought native support for SPM, including iOS!

    As the official package manager for iOS development, this should be the default choice used in Readium projects.

    I think this could also simplify the build settings of the test app, that are right now split between Carthage and submodules. We could maybe use only SPM, setup either with a direct path to the submodules or with the URLs to the Git repositories.

  • How can I set full-screen background image

    How can I set full-screen background image

    There are two questions: I try to set full-screen background image to each page of one chapter and the cover page. To do so, I set the Navigator full-screen, then the top bar and bottom bar just cover the Navigator. The first question is how to set the top/bottom margin of each page, since the top/bottom line of text is covered by the top/bottom bar content. Another question is about the background image. I use the css style "background-repeat: repeat-y;". It work well in Android with Readium SDK, but not work in iOS with R2.

  • Restoring last read position occasionally fails, opening EPUB to beginning of chapter instead

    Restoring last read position occasionally fails, opening EPUB to beginning of chapter instead


    Reopening an EPUB trying to restore the last read position seem to work inconsistently, sometimes opening the book to the beginning of the chapter. This bug is currently blocking our transition to R2 which otherwise is complete.

    I am unable to reproduce the issue on iOS 14. However I can reproduce it roughly one time out of 5 attempts using the same steps, book, build and device on iOS 13, 12 and 10. (I never tried on 11.) It is easier to reproduce with long books trying to restore a position toward the end of one of the last chapters, but it's pretty random.

    I can't reproduce this in the r2-testapp but I'll try to explain what I tried in detail what I am observing.

    Build / Test Set-up

    • Xcode 11.5 toolchain
    • carthage 0.36.0
    • R2 version 2.0.0-beta.1
    • test devices: iPhone 11 iOS 14.4 / iPhone 6 iOS 12.5.1
    • simulators: iPads / iPhones iOS 13.5, 12.4, 10.3.1
    • Focusing on epubs without DRM (e.g. Treasure Island, which is also present in the testapp). DRM'ed books exhibit same behavior though.

    R2 Set-up

    The way R2 is integrated in our app (SimplyE) matches the r2-testapp's -- as a matter of fact I copied its architecture. As far as restoring the reading position is concerned, my understanding is that one simply has to pass the desired Locator to the initialLocation parameter in the EPUBNavigatorViewController initializer. Is this correct or is there more to it?

    I also verified the locator i am passing is always the same, with or without experiencing the bug.


    I've tried to follow how the initialLocation locator is propagated at runtime inside the R2 navigator code, to try to understand where it is getting lost. I see that it is passed to the reloadSpreads(at:) function, and there i verified a non-zero initialIndex is always found.

    The code then flows to PaginationView::setCurrentIndex(_:location:) and then loadView(at:location:completion:). I verified the guards in those functions are not triggered.

    From there control passes to EPUBReflowableSpreadView::go(to:completion:), which may be called multiple times during initialization from many places. I assume this is expected?

    This is where things get confusing. When the bug happens the last go(to:completion:) call is for a Locator with progression == 0. This seems to come from a polling timer, for updating the user setting style. In this last function invocation we call go(to:) with the currentLocation value, which is incorrect because its progression is 0. Shouldn't that still be the initialLocation i passed in in the navigator's initializer, since the reader is still setting itself up? (There's a spinner on the screen at this time.) I just can't figure out where that initialLocation ends up going, or why/if it's being overwritten.

    From another POV, I noticed that on the r2-testapp navigator(_:locationDidChange:) is called twice (once with progression==0, then with the correct locator) but on our app it's only called once, and when the bug happens the locator.progression is 0. That callback is also called from another polling timer, which makes me think order of execution is not guaranteed to be identical across 2 identical instantiations of the navigator.

    I also noticed that if i start putting a lot of breakpoints with debugger output (which slows down execution), the bug is more likely to be triggered. This hints at possible race conditions, but it's just a conjecture.

    Long write-up, sorry... final thoughts

    I've tried many other approaches (e.g. trying to follow the spreads set-up, or how the Locator progression property is being set) but probably i should stop here since I'm rambling at this point.

    Thanks in advance for any help/pointers/suggestions. I realize the fact that the r2-testapp is fine probably means I have a bug in my set-up, but on the other hand this random behavior could mean something is off inside r2-navigator, but I ran out of things to look into.

  • Add user interface to search through a publication

    Add user interface to search through a publication

    (Please respond in this issue if you want to contribute this feature and have any question)

    The PR adds a new SearchService feature to search through the content of a publication. We need to expose this in the user interface of the test app.

    Here are some general guidelines:

    • SearchService is described in this proposal.
    • The search interface needs to be added for the ReaderViewController if publication.isSearchable is true.
    • It would be best to load the next page of results ( when scrolling to the end of the results table view)

    Starting a search

    To start a new search, use It will asynchronously return a SearchIterator if the search is valid. This iterator can be used to get the search results.

    let cancellable = "banana") { result in
        switch result {
            case .success(let iterator):
                // show results using iterator
            case .failure(let error):
                // display error

    Showing the results

    The results will be displayed in a table view. Every time the user scrolls to the end of the scroll view, you need to request the next page of results with It will return a LocatorCollection, or nil if the search is finished.

    let cancellable = { result in
        switch result {
            case .success(let collection):
                if let collection = collection {
                    // append `collection.locators` to the table view
                } else {
                    // search is finished
            case .failure(let error):
                // display error

    For each Locator cell:

    • If locator.title is different from the previous locator.title, create a new section with this title in the table view
    • Display the locator.locations.totalProgression in the cell
    • Display the search snippet with locator.text.before + locator.text.highlight + locator.text.after, putting emphasis on the locator.text.highlight portion.

    Cancelling the search

    When the user cancels the search, you need to dispose of the search properly:

    • If didn't return an iterator yet, call cancel() on the Cancellable returned by
    • If a SearchIterator was received:
      • call cancel() on the Cancellable returned by the last call
      • call iterator.close()

    Install using CocoaPods not resolving right GCDWebServer

    I tried to install r2-streamer-swift using CocoaPods and saw that it has GCDWebServer as a dependency.

    The issue is that the Cartfile uses a forked ( and working ) version of GCDWebServer ( erdlab/GCDWebServer ), meaning that the Cocoapods installs can't work without that exact dependency.

    Is there any reason why the forked version of GCDWebServer isn't available on CocoaPods ? If no, can we publish the forker server on CocoaPods to then update the podspec file of this project ?

    • The new NavigatorDelegate.navigator(_:didJumpTo:) API is called every time the navigator jumps to an explicit location, which might break the linear reading progression.
      • For example, it is called when clicking on internal links or programmatically calling Navigator.go(to:), but not when turning pages.
      • You can use this callback to implement a navigation history by differentiating between continuous and discontinuous moves.



    • Publication.format is now deprecated in favor of the new Publication.conforms(to:) API which is more accurate.
      • For example, replace publication.format == .epub with publication.conforms(to: .epub) before opening a publication with the EPUBNavigatorViewController.



    • The LCPService now uses a provided HTTPClient instance for all HTTP requests.



    • #14 Backward compatibility (iOS 10+) of JavaScript files is now handled with Babel.
    • Throttle the reload of EPUB spreads to avoid losing the position when the reader gets back to the foreground.


    • Fixed the notification of acquisition progress.

  • 2.2.0(Nov 9, 2021)

    Take a look at the migration guide



    • Support for Paragraph Margins user setting.


    • A new translate EPUB and PDF editing action is available for iOS 15.



    • Improved performances of the search service used with EPUB.


    • Fixed turning pages of an EPUB reflowable resource with an odd number of columns. A virtual blank trailing column is appended to the resource when displayed as two columns.
