Apple Watch SDK and More Great App Developer News

image

App developers heard some great news today when Tim Cook announced that WatchKit, the software development kit for building apps for the upcoming Apple Watch will be released next month (November)!

As I discussed previously in my Developing Next-Generation Apps for the Apple Watch post, this provides a great opportunity for app developers to get in the ground floor of a new technology and get noticed.



Swift Programming 101: Generics-A Practical Guide

image

If you have read Apple's documentation on Generics and were left wondering how you could use this technology in your own projects, this post is for you! You will learn how to take full advantage of generics in your every-day code as well as how to avoid the constant type-casting that usually results from creating generalized code.



Swift Programming 101 - Understanding Access Control

image

Access Control is one of the late-breaking features added to the Swift language. It allows you to specify the parts of your code you want to make public, and the parts you want to hide. It's an important tool in creating easy-to-use, and easy-to-understand interfaces.



Swift Programming 101: Demystifying Swift's Initializers (Part 2)

image

In this second part of my two-part post on Demystifying Swift's Initializers, I explain the concepts of initializer chaining, two-phase initialization, and initializer inheritance using hands-on examples that walk you through some of these deeper concepts. You can read part 1 of this post at this link.

If you would like to follow along and perform the step-by-step instructions with this post (highly recommended) you can download the project we have completed so far at this link.



Swift 101: Demystifying Swift's Initializers (Part 1)

image

Now that Apple has officially released Xcode 6 and the NDA has been lifted, it's time to dive deeper into Swift—Apple's new language for building iOS apps. Learning how to properly use initializers in Swift can be daunting at first. Swift's requirement that all stored properties in a class are initialized adds complexity to the initialization process. In the first part of this two-part post I'm going to demystify initializers as I provide a hands-on approach to learning how to best implement initializers in your custom classes.



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

image

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

image

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:

If you are just getting started now, check out the beginning of the series here(This post has been updated to iOS 7.1.)

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!



Unleash Your Inner App Developer Part 16: Tuning Up Core Data

If you are just getting started now, check out the beginning of the series here(This post has been updated to iOS 7.1.)

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.
