A Swift wrapper around Facebook's CSS flexbox implementation for programmatic layout in iOS/macOS apps.
SwiftBox is a Swift library that wraps Facebook's css-layout implementation, bringing CSS flexbox capabilities to native iOS and macOS development. It allows developers to create responsive, complex layouts programmatically using flexbox concepts like flex, direction, and alignment, without relying on Auto Layout.
iOS and macOS developers who need programmatic control over UI layouts, prefer flexbox semantics over Auto Layout constraints, or are building cross-platform UI components.
It provides a lightweight, predictable alternative to Auto Layout with the familiar flexbox model, reducing boilerplate and offering deterministic layout calculations directly in Swift.

Implements the CSS flexbox algorithm, making it intuitive for developers with web experience and reducing the verbosity of Auto Layout constraints for complex arrangements.
Defines layouts using Swift structs (Nodes) entirely in code, enabling version-controlled UI logic without Interface Builder dependencies.
Works on both iOS and macOS with a shared layout engine, allowing code reuse and consistent behavior across Apple platforms.
Computes view positions deterministically based on flex properties, offering reliable outputs and easier debugging for responsive designs.
Requires disabling Auto Layout for views, which can conflict with standard UIKit/AppKit components and break built-in behaviors like animation or adaptive interfaces.
Has limited community support, documentation, and third-party tools compared to Auto Layout, making adoption and troubleshooting more challenging.
Wraps Facebook's css-layout engine, tying the project to an external codebase that may not be actively maintained or updated for new Swift versions.
