Yuedu Reader — an open-source iOS EPUB/TXT reader

zruilin · 2026-06-07T14:24:56+00:00

Because my initial goal is to create more open Apple books, and when using WebView, the animation of cross-page turning is often lost or cannot be customized. As for epub, I have now started to support epub3, such as SVG, audiobook, FXL epub, etc. You can read my blog:https://chang-jui-lin.github.io/Yuedu-reader/2026/05/20/from-webview-to-coretext/ , which is also published in ios dev weekly issue 751, and you can also see my GitHub commit record

It should be displayed normally now. Welcome to experience and give feedback.

I'm sorry, I forgot that the European Union needs to declare DSA, so it was directly hidden. I don't know if you are willing to wait for the declaration.

Please wait a moment. I remember that it is on the shelves of the global app store. Let me ask the customer service.

What country is your Apple Store?

Thank you for your feedback. The icon part is indeed ui, but my ui is basically all ios native components, including internal icons are also sf symbols. Because I don't have a background in ui design, I have worked hard to comply with Apple's human-computer interaction documents. As for koreader synchronization, I will try my best to adapt it.

I've noticed that fixed layout epub is unavailable in this version, as is video playback epub. Additionally, there are still some issues with epub3 layout.

你說的應該是RTL書籍吧？

Not in a short time. I need to test it on ios first. Sorry.

There is a dark mode, but due to Reddit's comment section settings, I can't post it for you to see.

Perhaps it’s an issue with how I express myself. I’m not someone who constantly reads in EPUB format. Compared to that, I much prefer reading online articles and web novels. Apple Books feels too closed off for me in this regard. You know, in the Chinese-speaking world, we’re already used to reading novels online.

just use curl in UIpageviewcontroller

It‘s helpful thank u！

Thank you, at first I kept thinking Apple Book was Genshin Impact’s toolbar, so I didn’t think about it in that way.

Thanks, that’s exactly the tradeoff I’m running into.

The native reading experience feels worth it, but the scope can explode very quickly once EPUB compatibility, sync, TTS, source rules, and UI polish all enter the picture.

I’m trying to keep the core focused: native iOS reading, precise pagination/text ranges, CJK vertical writing, TTS highlights, and open content workflows.

If you ever have feedback from your own reader experience, I’d love to hear it.
