As promised, here is my first installment on learning to program in the new Swift language!

Defining Classes in Swift

The following code shows an example of a Swift class definition:

To declare a class in Swift, you use the class keyword followed by the name of the class. If it has a superclass, you add a colon and the name of the superclass. The beginning and end of the class are indicated by the opening and closing curly braces.

Over the years I have literally taught tens of thousands of people how to write code in Objective-C through training classes, conferences, online forums, and my book series. Based on the mountain of feedback I have received, I can tell you some key points that make Swift much easier to learn than Objective-C.

If Objective-C is the only language you have ever coded in, I have one thing to say about moving to Swift. Welcome to the 21st century.

If there was a common theme for WWDC 2014, Tim Cook articulated it at the end. He said what's great about Apple products is that their operating system, devices, and services work together in harmony, creating a seamless experience for users. And that seamless experience was expanded in dramatic fashion today, with the announcement of new technologies such as HomeKit, HealthKit, iCloud Drive, and Continuity. Apple also announced a ton of new features for built-in apps in iOS 8 such as Mail, Messages, Photos, and Safari.

Do you have an idea for an app but lack the programming knowledge to begin building it? In this weekly blog series, I will take you, the beginner app developer, 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 app ideas into reality can be! This is part 41 of the series. If you are just getting started, check out the beginning of the series at this link.

These days, more and more iOS apps offer users the option of logging in with Facebook. If you want your app to go viral, this is a great first step. In fact, 80 percent of the top-grossing iOS apps use social media logins. As stated in the Facebook documentation:

When it came to the iPod, I was an early adopter. And boy was it emancipating to no longer tote around CDs in my car or carry a Discman with me on the run. In fact, it was incredible.

At the time that the iPod emerged, smartphone apps were science fiction, like flux capacitors and hoverboards. But now, smartphones are not only ubiquitous, they are boasting more flexibility and nearly as much storage capacity as iPods. Could it mean the death of the iPod in the coming months and years? Maybe…

As much as I love Apple, I like what Microsoft is trying to do. But, heaven help me, I can't stand their commercials. "Honestly" starts each actor's fake testimonial. As if it wasn't obvious that these are primarily actors (except Seattle Seahawks player Russell Wilson) reading someone else's lines, by using the same words and format, Microsoft is being phony from the beginning in commercials that start and end with the word "Honestly." It insults the intelligence of the audience. Not to mention the valid charges of sexism. Interestingly, when searching using Yahoo (powered by Microsoft's Bing) none of the negative articles about the commercials show up, but under Google, they do. Whose search engine is being honest, now?
