Web Browser project adopts the industry's respected MVVM (Model-View-ViewModel) architecture, providing developers with a clear and scalable code structure. The code base is clearly divided into Models/, Views/, ViewModels/, Services/ and AI/ and other modules , each directory assumes a strict boundary of responsibility .
In the Models layer, the project defines core data models such as Tab, Bookmark, etc.; the Views layer uses SwiftUI to build modern interface components; the ViewModels layer handles complex business logic and state management; the Services layer encapsulates system-level services such as download management, history, etc.; and the AI/Catalog manages independently all machine learning related functions.
This architectural design makes the development of new features modular. For example, to enhance the ad-blocking feature, developers only need to extend the relevant implementation in the Services/ directory. The project also strictly follows Swift 6 concurrency rules and maintains zero warning/error code quality. Developers can adjust AI model parameters by modifying files such as AI/GemmaHandler.swift, or optimize the summary generation algorithm by extending ViewModels/AISidebarViewModel.swift.
The contribution process of the project is standardized , including Fork repository , create feature branches , submit PR and other standard open source collaboration process , to facilitate developers to participate in the co-construction . This standardized architectural design makes Web a quality reference project for studying modern browser development.
