How-To

If you're concerned about your iPhone's battery life, knowing what apps are using up your battery life is a good practice. Of course, if you use an app a lot it’s always going to show up as the app using most of your battery. But sometimes an app running the background or not working properly will drain your battery life too, and it’s good to be aware of them. This feature gives you a clearer picture of what's going on. Here’s how to find out which apps are draining your battery on iPhone.

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.

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:

Apple is great about making the latest operating system run on older equipment. But just because you CAN do something doesn't mean you should! There are reports from iPhone 4S owners that suggest they might have been better off without upgrading.

As an App Developer, every new release of iOS means a scramble to make sure my apps are compatible, and usually they are. But once in a while, Apple changes things just enough that old apps need to be tweaked to work with the new operating system. Making a living on the App Store, while difficult, is possible, but you have to keep your apps updated and add new features as Apple adds capabilities. The sad fact is, not every developer does that. Indeed some developers will be probably have apps in the App Store that simply won’t work on iOS 8, and never will. The developers may have shut their doors, and there may be no plans to fix incompatibilities.
