PMJSON

PMJSON provides a pure-Swift strongly-typed JSON encoder/decoder as well as a set of convenience methods for converting to/from Foundation objects and for decoding JSON structures.

The entire JSON encoder/decoder can be used without Foundation, by removing the files ObjectiveC.swift and DecimalNumber.swift from the project. The only dependency the rest of the project has is on Darwin, for strtod() and strtoll(). The file ObjectiveC.swift adds convenience methods for translating between JSON values and Foundation objects as well as decoding from a Data, and DecimalNumber.swift adds convenience accessors for converting values into NSDecimalNumber.
