Developing Next-Generation Apps for the Apple Watch

image

The word is out! The new Apple Watch is coming your way in early 2015, providing a brand new platform and great opportunities for a new category of apps. In this post I'll cover some of the basic features available for app developers so you can begin thinking about how these features can be put to use in your own custom apps.



Swift 101 - Working with Swift's New Optional Values

The Swift programming language has a new feature called optionals that were not previously available in Objective-C. They are similar to optional types in Java and nullable types in the C# programming language. 



Unleash Your Inner App Developer Part 18: Core Data Behind the Scenes

Do you have an idea for an app but lack the programming knowledge to begin build it? In this weekly blog series, 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 18 of the series. If you are just getting started now, check out the beginning of the series here(This post has been updated to iOS 7.1.)

We've been discussing Core Data in my last several posts and now you should understand the basics of:

In my previous post, you learned how to generate Objective-C classes from entities in a data model and you were introduced to the mmBusinessObject class, which provides an easy-to-use wrapper for Core Data classes. In this week's post, we're going to create our app's custom business controllers and take them for a test drive!

In my previous blog post, you learned how to add Core Data to a project and how to design entities in a data model. In this post, you will learn how to generate entity classes from the entities in a data model and use them within your app. You can get the latest version of the iAppsReview project at this link.

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.

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.

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.

One of the best software development books of all time is Steve McConnell's Code Complete. Whether you are a seasoned software developer or a brand new programmer, regardless of the platform or language in which you write code, I highly recommend checking out this book. It will change your way of thinking and vastly improve the quality of the code you write.



Swift 101 - Swift Meets the Cocoa Touch Framework

image

Even though Apple has provided the new Swift programming language for building iOS apps, one thing remains the same—we still use the Cocoa Touch Framework libraries to build iOS functionality into our apps. However, since the Cocoa Touch Framework is written in Objective-C, how is this accomplished? In this article I'll show you the mechanics behind how Swift accesses Objective-C code, and how the Cocoa Touch APIs (application programming interfaces) change when you access them from Swift.
