A tiny Swift DSL for AutoLayout that provides a declarative syntax for expressing layout constraints as linear equations.
SwiftAutoLayout is a tiny domain-specific language (DSL) for AutoLayout in Swift that provides a declarative way to express layout constraints. It replaces the verbose `NSLayoutConstraint` API with a concise, equation-like syntax that mirrors the linear equations AutoLayout uses, making constraint definitions more intuitive and readable. The library simplifies creating and managing AutoLayout constraints by using overloaded operators and property extensions.
iOS and macOS developers working with AutoLayout in Swift who want to write cleaner, more maintainable layout code without the boilerplate of the standard `NSLayoutConstraint` API.
Developers choose SwiftAutoLayout because it dramatically reduces verbosity and improves readability by expressing constraints as natural linear equations. Its lightweight, declarative approach integrates seamlessly with existing AutoLayout workflows while providing a more intuitive syntax.

Transforms verbose NSLayoutConstraint code into readable linear equations, as shown where `view1.left == view2.right * 2.0 + 10.0 ~ 750` replaces multiple lines, aligning with AutoLayout's mathematical foundation.
Provides direct properties like `UIView.width` for all layout attributes, simplifying access without manual enums and supporting views and layout guides on both iOS and macOS.
Uses the `~` operator to set constraint priorities directly in expressions, streamlining complex layout definitions without separate property assignments.
Offers consistent syntax for iOS and macOS, with properties for `UIView`/`NSView` and layout guides, enabling shared layout logic across Apple ecosystems.
Relies heavily on overloaded operators which can be confusing for developers new to the DSL or lead to ambiguity in complex, nested constraint expressions.
Does not support newer UI frameworks like SwiftUI, making it irrelevant for modern projects adopting declarative paradigms and forcing dual codebases for mixed environments.
Focuses on syntax simplification but lacks built-in tools for constraint animation, debugging, or dynamic layout changes, requiring reliance on standard AutoLayout workflows.
