Hour 5. Using Compiler Directives

Exploring Your Project
If you have followed the steps in Hour 4, “Organizing Projects with a Git Source Code Repository,” you now have your first Xcode project built in Objective-C. It does not do much (it opens an empty window and puts up a menu bar), but it runs. The structure of the project is the same as most of the projects you will build with Xcode, so this hour walks you through the few lines of code that have been generated for you. When you understand the structure, you can start to add your own code.
