Do you have an idea for an app but lack the programming knowledge to begin building it? In this weekly blog series, How To Unleash Your Inner App Developer, I will take you, the non-programmer, step by step through the process of creating apps for the iPhone, iPod Touch, and iPad. Join me each week on this adventure, and you will experience how fun turning your ideas into reality can be! This is Part 3 of the series. If you're just getting started now, check out the beginning of the series here (This post has been updated to iOS 8.0, Xcode 6.3 and Swift 1.2.)

In my previous post, we started the process of creating a prototype of an iPhone app called iAppsReview. You learned how to create a new project in Xcode, how to add a storyboard to a project and configure it, and how to add a navigation controller to a storyboard. You had just begun to configure the table view, which we will finish in this post. You'll learn how to create multiple sections in a table view, set section header text, add images to a project, and incorporate them in table-view cells.

After introducing the tools you'll need to develop apps in my previous post, I assume you've installed Xcode and are ready to get a taste of app development! I find there is no better way to learn than by doing, so let's dive in and start creating an app.

Extensions are one of Swift's best features. Extensions allow you to add behavior to existing classes, including classes in the Cocoa Touch Framework. Apple can't add every feature you want to their framework classes, but they have provided a tool to allow you to do it yourself! In this article, you will learn practical uses for Swift extensions you can use immediately in your iOS projects.

In part 2 of this post on Swift's protocols, you will learn practical uses for declaring custom protocols in your own apps, and learn further how they improve the architecture of your apps and make them easier to enhance and extend.

In part 1 of this post, I demonstrated how to implement existing Cocoa Touch protocols in your apps. Now you'll learn how and why to create your very own. First, we need to cover the basic construction of a Swift protocol.

In previous posts I have touched on inheritance in Swift. In this post, I'm going to be diving deeper and giving you a fuller picture of how inheritance works in Swift, and how you can use it to create apps that are easy to extend when you need to add new functionality. Along the way, you will also learn about the important concept of polymorphism and learn how to use Xcode's new playgrounds!
