Lecture #4 is mostly theory with a tiny demonstration in between.

It starts with an introduction to foundation objects and how to create them using initializers or special class methods. The demo shows how to use introspection to safely use dynamic typing.

New for iOS 7 is preferredFontForTextStyle for fonts and font descriptors.

The lecture ends with attributed strings …

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.
