This chapter will walk us through the steps needed to set up Xcode as well as the development of the SimpleCalc App. SimpleCalc will allow us to take two numbers and perform addition, subtraction, multiplication, and division. This App is intentionally kept simple because we have many things to learn about how to develop Apps in this chapter.
In this chapter, we shall learn the following:
Installing the Xcode App
Creating a new Xcode project
Configuring an Xcode project
Creating an App Icon
Configuring an Xcode target
Creating a user interface
Implementing a Mac OS X App behavior
Building and running a Mac OS X program
