In this lab, you will experiment with Objective C fundamentals in a Mac terminal application that does not display any user interface. Everything you do in this lab is applicable to iOS as well – we will not use any API that is not available in iOS.

Begin by creating an Xcode project of type OS X > Application > Command Line Tool. (In the Type combo box, select “Foundation” if it isn’t selected.) Add classes as necessary per the instructions below using File > New > File, OS X > Cocoa > Objective C Class.

Implement a PlayingCard class that has the following methods, initializers, and properties:

• NSString* suit property
• NSUInteger rank property (valid values are 1-13, where 1 = “Ace”, …, 13 = “King”)
• NSString* contents read-only property that returns the card name (e.g. “Jack of Spades”)

• Windows SDK for Windows 8.1

Additionally, the labs we will use during the workshop are available here. Please download and extract the files before the workshop.
