+**Masonry is no longer actively maintained, going forward we recommend using [SnapKit](https://github.com/SnapKit/SnapKit) as it supports Swift and provides better type safety with a simpler API**

 Masonry is a light-weight layout framework which wraps AutoLayout with a nicer syntax. Masonry has its own layout DSL which provides a chainable way of describing your NSLayoutConstraints which results in layout code that is more concise and readable.
 Masonry supports iOS and Mac OS X.
