iPhone Life - Best Apps, Top Tips, Great Gear

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 15 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).

In my previous post in this series, I discussed some of the basics of Core Data, the technology that allows you to store and retrieve information on an iOS device. You learned about entity data models, databases, and how you can improve on Apple's default Core Data implementation.
