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 14 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)

Core Data is the technology that allows you to store and retrieve information on an iOS device. Although it is an advanced technology often difficult to grasp, my goal in this post is to simplify Core Data so it can be easily used by beginners.

As anyone who has used to Siri to make calls, search the web, or send messages knows, Siri doesn't always understand what you say. This can be followed by increasing frustration levels if Siri fails over and over to understand your voice corrections. But when Siri gets it wrong, you don't have to repeat yourself. Instead, you can edit your query via typing.

There is nothing like the post-Consumer Electronics Show fulfillment of promise, as things that were just demos in January start to ship. I spent the last month reviewing a wide variety of headphones, earbuds, and other audio devices. Here are my thoughts on a dozen ways to bring audio into your life, categorized by type: mono earbuds, stereo earbuds, on-the-ear headphones and over-the-ear headphones.

The Wordflex Touch Dictionary (free) is the most beautifully rendered touch-based reference technology you will hold in your hand. I only barely exaggerate how amazing it is to use. The last thing I want to do when researching a topic or looking for word substitutes (like the word "amazing"—I so overuse that word) is have to crack open an actual dictionary or thesaurus. It's both boring and silly in 2015. Why not watch the English language and it's various phylum unfold in graceful symmetry on the iPad screen!? The new version is now available without the need to spend one's shekels to attain it. Witness the beauty after the break!

If you're not already using location-based reminders, you are missing out on one of the coolest features of the Reminders app! Location settings in Reminders can help you remember things based on when you're next arriving at or leaving a location, so you won't forget to pick up milk next time you're near the grocery store, for example. We'll show you how to use this handy feature.

You can save a ton of money on an iCloud storage plan, Apple Music subscription, and purchases from Apple Music, Books, TV, Game Center, and the App Store. How? By using Apple Family Sharing, a money-saving program that allows up to six family members to share Apple Music and much more. The whole family can access the same content across multiple devices without sharing accounts. Once you've set up Family Sharing and started your family group, it's simple to add a family member; you can invite new members at any time. We've already gone over how to set up Family Sharing and how to share an Apple Music family plan with Family Group members. Now, here's how to send and accept family sharing invitations, so more family members can save money by sharing Apple purchases.

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.
