SwiftParsec is a Swift port of the Parsec parser combinator library. It allows the creation of sophisticated parsers from a set of simple parsers. It is also easy to extend the available parsers. The parsers are fully integrated into the language, they can be put into arrays, passed as parameters, returned as values, etc. SwiftParsec provides expressiveness, is well documented and simple.
