John Sundell has put together a really handy Swift library called Unbox. It provides a straightforward interface for marshalling JSON data into Swift data models and it supports all the standard JSON types out of the box.
I like it better than the approach taken in ObjectMapper because Unbox supports immutable (
let) properties whereas ObjectMapper currently requires all properties to be mutable. It does look like ObjectMapper is in the process of adding an
ImmutableMapping protocol which should be a big improvement, but I think Unbox is probably the better choice right now.
