Snappy is a light-weight layout framework which wraps AutoLayout with a nicer syntax. Snappy 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. Snappy supports both iOS and OS X.
-> Snappy uses some Swift only features like function overloading it cannot be used from Objective-C. Because of this we’ve chosen to swap prefixes from Masonry’s `mas_` to `snp_` so you can use both Masonry and Snappy in the same project.
