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 much fun turning your ideas into reality can be! This is Part 13 of the series. If you are just getting started now, check out the beginning of the series here. (This post has been updated to Swift 1.2, iOS 8, and Xcode 6.3)
This post contains some of the most important information you need to know to build a well-designed app that easily adapts to changes requested by users, the constant changes Apple makes to iOS, and the ever-changing landscape of iOS devices. It all comes down to a solid app architecture. We're going to take a quick digression from the iAppsReview app this week to look at a simpler Calculator app to help us establish good architectural principles.
