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.

There is a commonly held belief that men don't like to ask for directions. As a guy, I am here to say it's true. At least for me. With Siri, I can ask for directions without anyone knowing.

Apple has announced they expect third party apps to support Dynamic Type. However, if you have tried to implement it in your apps, you know there are some unexpected land mines along the way (such as static table view cells and custom cell styles). In this article, you will learn how Dynamic Type works under the hood and how to get it working properly in a variety of scenarios. You will also get some Swift code that makes it easier to implement Dynamic Type in your apps.

If you read that headline and thought, "Wait, what? Of course I want to be an iOS ninja. How do I get started?" you should definitely sign up for the iPhone Life Tip of the Day Newsletter. In fact, here's our list of all the people who could benefit from receiving our short but super handy iPhone tips and tricks everyday in their inbox:
Some people say that Pinterest is the new Google. People head to Pinterest to search for project ideas, recipes, and news about their favorite topics. Using the Follow Interest tool, you can easily find new pins about your favorite topics without following other pinners one at a time. Pinterest will find the most popular pins from all of of the users who are posting about the topics you love and display them in your Pinterest feed. I've used this feature to find new pinners to follow and find more great pins about my favorite topics: health & fitness, technology, and DIY.

Have you always wanted to build an iOS app, but lacked the knowledge and skills? Have you ever signed up for an online course on creating iOS apps, only to feel frustrated because the content was out of date or not comprehensive enough? Are you dying to learn more about Swift and programming for the Apple Watch? It's a story we hear all the time at iPhone Life. And that's why we decided to partner with iPhone app expert, former Apple employee, and adjunct professor at RIT Paul Solt to make his iOS development courses available to iPhone Life readers at a big discount.

Extensions are one of Swift's best features. Extensions allow you to add behavior to existing classes, including classes in the Cocoa Touch Framework. Apple can't add every feature you want to their framework classes, but they have provided a tool to allow you to do it yourself! In this article, you will learn practical uses for Swift extensions you can use immediately in your iOS projects.

How would you like to extend the surface area of your app's user interface exponentially? How would your users react if you added multiple display devices to your app, each containing different content? All of this is possible by using an iOS feature many developers are not aware of—external displays.

In a recent post I noted that iOS 8.1.1 is now available for download. This morning I added a sentence to that post reminding people to BACK UP FIRST. That's because it's not uncommon for something to go wrong when one updates. For example, when I updated to iOS 8, I encountered an error, and the only way to get my iPad out of it was to restore to factory settings. Doing so means that everything is lost. Fortunately, I had backed up first, so it wasn't a problem.

Swift's advanced collections can help you model more complex objects in your apps and create an API that is easier to understand and use. In this post, I model a chessboard using Swift's subscripts and also cover tuples and multidimensional arrays!

In part 2 of this post on Swift's protocols, you will learn practical uses for declaring custom protocols in your own apps, and learn further how they improve the architecture of your apps and make them easier to enhance and extend.
In part 1 of this post, I demonstrated how to implement existing Cocoa Touch protocols in your apps. Now you'll learn how and why to create your very own. First, we need to cover the basic construction of a Swift protocol.
By Kevin McNeish
Protocols are a powerful, advanced tool that help make your apps easier to design and extend. They define standard behavior in classes that are not necessarily related. Protocols used together with delegates allow you to create classes with a well-balanced load of responsibilities.

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!

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.

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.

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.

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 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.

Have you ever wanted to tell Siri to keep it down or to speak up, but couldn't find where in the settings to adjust the virtual assistant's volume? That's because there is no Siri volume control in Settings.
Asking Siri to adjust it's own volume doesn't work either. You may recognize these Siri replies from your own attempts to adjust the volume:

Apple does not limit the character count for iMessages; but if you are sending a message to a non iUser it will be sent as an SMS and will therefore be limited to 160 characters. This means characters over 160 will be sent in a second text or possibly even deleted, depending on your recipient's carrier. To avoid this situation, turn on Character Count so you can always know when you've reached the SMS character limit.
