Masonry is a lightweight Objective-C framework that wraps Apple's Auto Layout NSLayoutConstraints in a chainable, expressive DSL. It simplifies creating constraints in code for iOS and macOS apps, with Swift users directed to its successor SnapKit.

Use cases

  • create autolayout constraints in objective-c without verbose nslayoutconstraint code
  • lay out uiviews programmatically with a chainable syntax
  • pin a view to its superview edges with insets
  • replace storyboard constraints with code-based layout
  • maintain legacy objective-c ios app layouts

When to choose

  • you are writing an Objective-C iOS or macOS app and want concise Auto Layout code
  • you are maintaining an existing codebase that already uses Masonry
  • you prefer a lightweight DSL over verbose NSLayoutConstraint APIs

When to avoid

  • you are writing Swift - use SnapKit instead for better type safety
  • your project relies primarily on Interface Builder or SwiftUI for layout
  • you need a library with active feature development rather than maintenance
