what is hanairo fr?

Hanairo is an unofficial app for browsing Pixiv, the Japanese art and comic sharing site, built for iPhone and other Apple devices using SwiftUI and following what the developer calls a liquid glass design style. It is not made or endorsed by Pixiv itself, just an independent client that talks to Pixiv's own service. Inside the app you can see recommended illustrations and comics, browse daily, weekly, monthly, and historical popularity rankings, follow public bookmarks and the activity of people you follow, search by popular tags, artwork, or user, and open multi page artwork with full detail including tags, author information, statistics, and related works. Viewing full size images supports double tap and pinch to zoom along with swiping between pages, and a floating action bar lets you bookmark, share, or download the original image. You can also view an artist's profile, follow them, and browse their full works list, along with general bookmarking, following, sharing, and content filtering features. The app requires you to log in before you can reach the main interface at all, using Pixiv's own secure browser based login flow, and it keeps you signed in afterward by storing your login token securely and refreshing it automatically, including retrying automatically if a request fails due to an expired session. The code is organized into clear layers: one part handles the app's screens and navigation, a components folder holds reusable SwiftUI pieces, and a core folder separates data models, networking and login code, secure token storage, and background services from each other, so each view only worries about what it shows on screen while requests and login state live in dedicated central places. To build it yourself you open the project in Xcode and run it, and it currently compiles for iPhone, Mac, and Apple Vision Pro. There is also a script for producing an unsigned iOS install file, and the project's automated build system can post each new build, along with a summary of recent changes, to a Telegram channel if you provide the right bot credentials. Because Pixiv's mobile interface is not an official public API, the developer notes that the networking code may need updates whenever Pixiv changes it on their end. The project takes inspiration from an existing Flutter based Pixiv client and is released under the Mozilla Public License 2.0.
