Lecture #2 provides a short walk through of the Xcode developing environment. The first half of the lecture discusses the various classes of the model for the playing card game. The second is a life demonstration on how to start a project in Xcodes, placing buttons and labels in Storyboard and connecting them to the view controller.
At the end of the lecture the app called Matchismo displays a playing card and allows to flip it to show both sides of the card.
The code for this lecture is available at github.
The lecture as well as its slides (which include a complete walk through of the demo from the lecture and most of assignment #1) are available via iTunes called “2. Xcode 5”.
