Working with dates is a task that is universally applicable to Swift developers. Particularly when dealing with an API, dates can arrive in all shapes and sizes. We‘ll examine some of the common ones such as ISO 8601, show how to parse these formats into Date instances, and how to use DateFormatter to display them back again as a string. We‘ll also cover the importance of using en_US_POSIX and honoring the user‘s Locale when displaying dates.

UITableView can support scrolling through many rows of data, however fetching large amounts of remote data can slow down your app, use up too much memory, and bog down your web server. This is all wasteful if users aren‘t ever going to scroll down that far. In this episode you‘ll learn how to perform automatic UITableView pagination using an easy technique.

In order to use CloudKit to read or write private data (or to write in the public database) the user will have to be signed in to iCloud on their device. If they are not, they'll not have a great experience, and things won't work. In this episode we'll check the account status before trying to save a record in CloudKit. We'll also respond to the notification to know when the user's account status has changed so we can react accordingly.

Continuing our build out of Road Trip DJ, this time I focus on the music player, and keeping the play/pause button in sync on UIToolbar, which proves to be more difficult than it should be.

In this episode we continue Road Trip DJ and implement the media picker controller, talk about the different modes that in can operate in and how that affects the usability of this app. We also consider how we're going to build a playlist and keep appending items to it.

#156
In this episode we start building an app from scratch called Road Trip DJ. The idea is the build a playlist of music on the fly while it is playing. This is an app I've wanted to build for a while and it serves as a good, small app we can build from start to finish.

This week we have another free bonus video on the improvements that Xcode 5 brings to Autolayout. As something that has been quite obnoxious to work with in the past, many people dismissed auto layout when it was introduced to iOS 6. With these improvements it is much more friendly and dare I say... usable?

In this episode, we'll set up a free continuous integration server called Jenkins (previously Hudson) to run our build. We'll configure it to automatically check out changes from git, run the build, and finally run all of our tests. We'll then use a conversion script to translate the test output into JUnit test report files that Jenkins natively understands.
