In this chapter, we have covered everything that we need to know to develop Mac OS X Apps.
Specifically, we covered how to install the Xcode IDE from the Mac App store and how to create a new Xcode project from a template. We then identified the different types of files needed to create a Mac OS X App. Then we customized the Xcode template and created a new icon for our App. Finally we created the user interface and actions for our App so that we could build it for installation into the Applications
folder.
Now that we've learned how to develop a basic Mac OS X App, we need to take a small diversion in our route to learn what to do when the unexpected happens and the debugger appears when least expected – which is the topic of the next chapter.
