#241
241 file downloads part 3
In this episode we take the download state and progress notifications and update the user interface to reflect this state. We'll see how to translate the notification into the indexPath for that episode row, and how to fake a change related to the fetched results controller to trigger a reload of the content. We will leverage the RateLimit library to save periodic changes in progress to the model without overwhelming Core Data.

#240
240 file downloads part 2
In this episode we create a DownloadInfo model in CoreData in order to track the state of a download, separate from any view controller.

#239
239 file downloads part 1
Downloading large files on iOS represents some unique challenges. Downloads should occur in the background, not confined to a particular view controller. They should be able to report progress on multiple screens, and should be robust enough to survive application suspension and failing network conditions, and respect the user's cellular data plan. In this episode we start a series on downloading large files that will cover all of the above concerns.

#204
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.

#194
194 modeling api endpoints
In this episode we talk about modeling API Endpoints as first class types, rather than relying on strings and string interpolation scattered across your application. For this we'll leverage Swift enums with associated values.

#89
089 networking in ios7 poster 1280
In this episode we take a look at the brand new NSURLSession family of classes. We'll consume the iTunes Affiliate Search API and show how to do a simple GET request.
