In this episode we continue our work on the Apple TV app for NSScreencast by adding a local cache of data we receive from the API. Doing so will allow us to have content immediately on launch without waiting for the network, and will also support client-side searching and filtering. Here we talk about how to set up Core Data with Swift and write a few quick tests using an in-memory store to verify that things are working.
