Tip of the Day: Recover Deleted Photos

image

If you like to use the camera on your iPhone or iPad, one of the features you'll appreciate in iOS 8 is the ability to recover deleted photos. When you delete a photo, it remains available in the Recently Deleted album on your device for 30 days. If you decide that in fact you want to save a photo you deleted, you can easily recover it.



Tip of the Day: Find Out Which Apps Are Draining Your Battery

If you're concerned about battery life, you'll want to check out the new feature in iOS 8 that lets you see what apps are using your battery the most. This usage can simply result from your using an app a lot, but other times apps have background processes that drain the battery or the app isn't working properly. This feature gives you a clearer picture of what's going on.



Tip of the Day: Recover Safari Tabs You Accidentally Closed

image

I constantly use tabs in Safari. When I'm viewing a page and see a link I want to read — but without closing the page I'm currently on — I tap and hold the link to open it in a new tab. I sometimes have as many as a half dozen tabs open. And nothing is more frustrating than inadvertently closing a tab when it's something I haven't yet read. Fortunately, if that happens to you, there's a simple way to re-open recently closed tabs.



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.



Tip of the Day: Use Siri to Identify Songs Playing on the Radio

image

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.



Tip of the Day: Turn off Predictive Text Completely

image

Can Apple read your mind? With iOS 8, it looks like it! Apple has caught up with Android and other platforms that offer a form of predictive Text called QuickType. This means, when composing text, your iOS device will suggest words that it thinks you want to use. While AutoCorrect guessed at a word, based on the letters you type, QuickType predicts what word you might type next based on the context of your message or document.



Tip of the Day: How to Turn On Grayscale Mode in iOS 8

image

Among the many new features of iOS 8 is grayscale mode. Why would you want your display to appear gray rather than in colors? There are two main reasons. First, for those who are color blind, items such as menus may be hard to distinguish if they rely on color to stand out from a background. Grayscale can make the display more readable for them. And second, if your battery is running low and you know that it will be a while before you'll have the opportunity to charge it, grayscale can extend battery life. 



Tip of the Day: How to Use iOS 8's Manual Exposure in Camera

image

Automatic exposure (which determines how light or dark our images should be) is so convenient and accurate most of the time, but then there are those times when we end up with  overexposed or underexposed images that make us cringe. After all, our cameras are pretty advanced, but it's still impossible for them to recognize when we want our focal point darker (such when shooting silhouettes) or lighter. 



Tip of the Day: Use Reader Mode in Safari for Easier Reading

image

Web pages are often cluttered with ads and menus, all of which can be distracting if you're just trying to focus on reading the text. Fortunately, Safari has a Reader Mode that removes all those distractions and presents the page's text and images in a simple and attractive fashion.



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.
