How-To

I like Apple's Maps app, but a number of times it's taken me to a location that simply didn't exist: an Indian restaurant, a zoo, a hotel in a small town, a Chinese restaurant. I diligently follow Siri's directions and when she says I've arrived, the establishment in question is nowhere to be seen. And in several of these cases probably never existed. If you've had similar problems and prefer maps from third parties such as Google, you can now conveniently access these maps from within Apple's Maps app.

In previous posts I have touched on inheritance in Swift. In this post, I'm going to be diving deeper and giving you a fuller picture of how inheritance works in Swift, and how you can use it to create apps that are easy to extend when you need to add new functionality. Along the way, you will also learn about the important concept of polymorphism and learn how to use Xcode's new playgrounds!

One of the great new features in iOS 8 is the ability to send an audio message. Sometimes it's simply a lot more convenient to make a quick recording than it is to type a message. Why not simply call the person? Because convention requires that we then engage in conversation. An audio message is more efficient. And the party you're sending it to can listen at his or her convenience rather than having to answer the phone.

iOS 8 finally brought the ability to customize the iPhone and iPad interface by allowing you to add widgets to the Today screen in Notification Center. In an earlier post, I explained the simple steps for doing this. You simply swipe down from the top of the display to view the Notification Center and tap on the Edit button at the very bottom. This reveals widgets that are associated with apps that you already have installed on your device. You simply tap on the green button to add a widget.

Vidget (free) is different. Instead of being an app such as ESPN Sport Center with an associated widget, its sole function is to let you easily add a bunch of widgets to your Today screen, with about 20 different widgets currently available.

You've probably had the experience of listening to the radio and wondering the name of the song that's playing—maybe it's new to you and you're wondering who the artist is, or maybe it's familiar but you can't remember the name. Now with iOS 8, Siri can help. In the past, you could ask Siri to identify music playing on your device, but with iOS 8 you can ask Siri to identify any ambient music. And, conveniently, Siri also makes it easy to purchase the song or album.

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.

Apple's new iOS 8 is great, and one of those great new features is Continuity. With Continuity, users of multiple Apple products can take a phone call on one device and switch to another on the fly. I typically leave my iPhone docked at the entrance to my house and then I work upstairs on my MacBook. When the phone rings, I have to make a mad dash to answer it. Now I can take the call on my iPad. And soon, with Mac OS X Yosemite, I can answer the phone call on my MacBook!

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.

The iPhone 5s gave us Slo Mo video capture, where images are recorded at 120 FPS (Frames Per Second) and then played back at 30 FPS. But now the iPhone 6 offers Super Slo Mo, which captures 240 FPS. This will allow for some incredible action videos. I played with this new feature at my daughter's softball game and was able to analyze her swing and running essentially in real time. This could be a great boon to coaches and athletes, not to mention a lot of fun! Here's how to use it:
