204 json api client part 2
In this episode we start writing an application-specific API Client. We use Argo to decode our JSON response into an Episode model, including some nested object decoding, date formatting, and wrap it up by testing the implementation to make sure it works.

#203
203 json api client
In this episode I start creating a reusable api client that will make it a lot easier to consume a JSON api and convert the response into model objects. It uses Argo for the JSON parsing, and leverages Swift features to provide a rich callback for the API calls.

131 swift json redux part 2 poster 1280
In this episode we wrap up our JSON parsing exploration in Swift by extending the decoding to work with arrays. Doing so cleans up the extraction code significantly.

#129
129 swift json poster 1280
Parsing JSON (which provides no contracts or type guarantees) can be difficult and tedious in Swift. Many of the problems you are forced to deal with were easier to ignore in Objective-C, but that doesn't mean they weren't present. In this episode we'll take a look at a very manual approach to mapping from a JSON response to a Swift type.

#121
121 mantle with core data part 2 1280
In this episode we continue with our mantle example, this time binding the code to the UI. This involves mapping back to our mantle model for display on the cell, as well as responding to changes using the NSFetchedResultsControllerDelegate protocol.

#116
116 mantle poster 1280
In this episode we go over a handy little model framework called Mantle. With Mantle we can easily get support for NSCoding, NSCopying, and JSON serialization for our model objects.
