An important new feature in Swift is option types, which allow references or values to operate in a manner similar to the common pattern in C, where a pointer may refer to a value or may be null. This implies that non-optional types cannot result in a null-pointer error; the compiler can ensure this is not possible.
This particular book is about as much – no, even more – than you can expect from a book introducing something like Objective-C, the iPhone SDK/xcode, and Cocoa Touch to an absolute programming “dummy”. Again, in typical fashion, I quickly glossed over the beginning and tried to jump right into the “fun stuff”. DON’T DO THAT. This book is so well organized and easy to read that you actually SAVE TIME by starting from the beginning and working your way through the examples and chapters. It doesn’t take long at all. I’ve made my way through 3/4 of it in about 4-5 days (only in free time) and I can say that I’m not even the same person today that I was 4 days ago – it really is that good. The book is calibrated to someone who knows NOTHING about any of this, but yet it doesn’t leave out the important things that everyone needs to know (e.g. the code examples). And when it’s “glossing over” something, it tells you exactly what someone like me needs. By the time you’re 3/4 of the way through this book, you will understand about 3/4 of what you need to know to be dangerous with xCode/interface builder, and the rest of iPhone SDK. Unfortunately, that 3/4 is not enough to get you to that killer app – and that 1/4 remaining is where the wheat is separated. You will eventually need to learn Objective C programming. BOTTOM LINE: if you want a quick orientation into iPad/iPhone programming, enough to orient you and set you on course, this is a GREAT start. With this foundation, you can easily build your skills in no time using additional resources which I mention below. The same thing is true if you’re new to Objective C but you’ve programmed other languages, such as C++. Only for those like that, you will get even more out of this book. I can’t recommend this enough.
Another key feature of ObjC is its use of protocols, known in most modern languages as interfaces. Protocols promise that a particular class implements a set of methods, meaning that other objects in the system can call those methods on any object supporting that protocol. This is often used in modern OO languages as a substitute for multiple inheritance, although the feature sets are not entirely similar. A common example of a protocol in Cocoa is the NSCopying protocol, which defines one method, copyWithZone, that implements deep copying on objects.

Video recordings of Stanford’s 10-week computer science class, taught by two Apple employees, will be freely downloadable through Apple’s iTunes U educational channel. The course’s syllabus and slides will be freely available on iTunes as well.
This course will be teaching iOS 6, the newest mobile platform from Apple which (with any luck) will be released in October. Last year, iOS 5 was released at the same time as the new iPhone 4S, at the beginning of October. So we would plan on shipping the early access beta of Try iOS in October, and the wide release a month later, in November.

To arrange your apps alphabetically, on your iPad, tap Settings > General > Reset > Reset Home Screen Layout. This will make your first page default to the original Apple apps. Beginning on the second page, your apps will appear alphabetically. You will have to do this each time you add an app to keep it in order or you can rearrange them after buying new apps.
While many of the iOS apps we are going to cover in this article do “double duty,” meaning that they are capable of more than one function, these iPad and iPhone apps generally excel in just one or two primary functions:
0:34. Let’s go over some stats before we get into how to make an iPad app, because most people don’t understand how it’s possible to create a free iPad app and generate a significant daily and monthly income. How are you able to make money when the app is free?
In regards of all these inconveniences, we are looking for an automatic process in order to minimize the margins of error and the waste of time and money. Our main requirement is that all these processes can be managed from one center of operations. We would like to be able to use a computer and/or Internet in order to run automatically the following operations:
Your new device offers the choice of restoring apps, data, and settings from your most recent iCloud backup, or updating your current device’s backup and then restoring. After you select a backup, you can choose whether to transfer some settings related to location, privacy, Apple Pay, and Siri. If you want to update the backup on your device, make sure that Wi-Fi is enabled on your device.
Let’s do this now and call our class myClass. XCode created both the interface and the implementation files for myClass and added the code we need to get started. The interface file is the one that ends in .h. If you open that file you will see the code that XCode automatically filled in for us.
Functional Reactive Programming or FRP is a combination of functional and reactive paradigms. Learn how to implement FRP using ReactiveCocoa. Get acquainted with the basics such as Signals, SignalProducers, Events and much more.
Customize the objects you add. You can adjust the properties for each object, allowing you to create a custom and intuitive interface. For example, you can add placeholder text to a text input field that will help guide the user on what they should input.
Learn how to create custom user interfaces for different screen sizes or orientations, which can be especially useful for iPhones. Then you will learn the basics of connecting your interface with your Objective-C or Swift code.
A mobile app will build a connection with your customers that goes beyond food and atmosphere, it builds loyalty with your patrons and helps increase restaurant traffic, empowering your business like never before. The restaurant app maker tool allows you to build and deploy a restaurant app that can take orders and reservations, showcase your menu, promote offers, and boost sales.
Add more screens. As your project grows, you will probably need to add more screen to display all the content necessary for the app to be useful. For example, if you are making a to-do list app, you will need at least two screens: one for inputting a to-do list item, and one for viewing the entire list.

Whether your organization requires a single course or an entire curriculum, Learning Tree has the expert instructors and management expertise to deliver quality training that meets your budget, program schedules, and business goals.
I’ve largely been platform-agnostic in this post. Even with all the advancements over the last several years, especially on the design side, Android apps are still much harder to build. Anecdotally, our experience is that Android apps take 2-3x longer than iOS apps. Steve Cheney, now at Estimote, had similar findings in late 2013. For this reason, the typical approach is still to start with iOS and then move to Android
Corona SDK. The Corona SDK uses LUA as a development language and then re-compiles to Objective-C. And because LUA is quicker to write, apps can be built much faster using Corona SDK. Corona specializes in 2D graphics and includes its own physics engine. You can also compile for both iOS and Android from a single set of code. Corona also supports building native Windows and Mac OS apps, but it doesn’t support consoles like the PlayStation 4 or XBOX ONE. Corona is a great choice for 2D games and casual games.
5. Lift the carrier and lay it upside-down along the back panel side of the tray. Don’t disconnect the brown plastic ribbon cable. From this vantage point, you can extract and replace the two SDRAM sticks, hard disk drive, and optional optical drive.
iPhone X is here. Download Xcode 9 and test your apps now to make sure they’re ready for the Super Retina display by respecting safe areas, supporting adaptive layouts, and more. Once your apps are ready, you can submit them for review.
Introduced in iOS 6, Apple’s Guided Access feature allows parents, teachers, and people with disabilities, to temporarily restrict the entire device to a single app. The home button is disabled, along with multitasking, allowing users to work within a single app without distraction.
The next thing I tried still involved using Xcode workspaces (I really thought that this was the way to go). What I did was create a group independent of any Xcode project in the workspace that held the shared code. This was once step up from what I did before.
The courses content will help delegates understand the basic and advanced concepts of iPad app development. Our iPad app development course in Stoke-on-Trent will allow you to interact with the tutor on a one-to one basis and receive tailored help to suit your learning needs.
Lilliput 7-inch touchscreen monitor (CarLCD.net #619GL-70NP/C/T; $245.00) NOTE: Sure, a 24-inch monitor ($349) would be much nicer, but this lil’ ol’ monitor provides a touchscreen input, which can be useful during testing with the iPhone SDK iPhone Simulator. You can download the Mac OS X Intel driver for this touchscreen monitor from EETI.
I’ll bet this describes at least some of you out there right? The reason I know this is that late last year I asked my readers what their biggest sticking points were. The overwhelming response to this question could be summarized by two words: Time and Tools.
Yet another option is to try a service like MacinCloud. It’s basically a remote Mac rental service that allows you to use Apple hardware through the Internet. You may have experienced something similar with remote services like Teamviewer. It’s a good option but can be slow.
Now that we have a working knowledge of many parts of the Swift language, it’s time to take a deeper dive and look under the hood. In this grab bag of a course, we’re going to look at many different topics including computed and stored properties, designated and convenience initializers, extensions, memory management and much more. By the time you’re done with this course, you’ll have a wider array of tools in your tool belt that will help you write more concise and flexible Swift.
