Swift 1.2 Is a Major Update—But Doesn’t Replace Objective-C

2015_02_25_Swift

The first beta of Xcode 6.3 was recently released with a new version of the Swift language that contains a number of significant changes.

Swift has a great deal of promise. It could make development for iOS and OS X both easier and more reliable. Unfortunately, much of its promise has yet to be realized.

Swift 1.2 is a major update that comes at the cost of backward compatibility, yet significant issues remain unresolved.

How to Make a Game with Unity

here's how to make a game with Unity

Game development used to be something you could only do if you were a brilliant wizard of a programmer.

But today there are game engines—and many of them free—which build in most of the guts of a game. All that’s required of you is a little scripting, and a lot of imagination.

Here’s how to make a game with Unity.

Use the Popular MEAN Stack to Build Web Apps

What's the MEAN Stack?

Web technology evolves at Internet speeds, so finding the right combination of solutions for your web apps can be tricky for a web developer. From front-end frameworks to back-end server and database environments, arriving at the right blend of technologies for your projects takes experimentation, trial, and error.

If you’re looking to streamline your existing web app development workflow, the increasingly popular MEAN stack (a handy acronym referring to the combination of MongoDB, Express.JS, Angular.JS, and Node.JS) is a great choice. Here’s what it is, and how to get started with it.

So You Want to Build Your First iOS App? Here's How.

build your first ios app

With over a million apps on the iTunes App Store, you might think that it’s easy to build an iOS app. And for experienced developers, that may very well be the case.

For guys like me, though—who have no experience with Objective-C (or Apple’s new programming language, Swift)—it’s harder than you think to build your first iOS app.

But it’s not impossible. You just need to know how to get started.

He Helps Fight Hunger in Rwanda. And lynda.com Helps Him.

2013-10-Sudan-Darfur-IDPCampVisit

At a time of year when many of us are filling our homes and our bellies with an abundance of delicious treats, Jules Rugwiro is fighting hunger in Rwanda.

Jules is a database manager with the UN’s World Food Programme (WFP), the largest humanitarian agency that addresses hunger.

“The work that we do includes providing food and/or cash for refugees, responding to emergencies, feeding school children, and connecting farmers to markets,” says Jules, a Rwandan who lives and works in Kigali, the nation’s capitol. “I collect information on whether food is available and accessible, and how it’s utilized by people in different parts of the country. Once we have this information, we identify who the vulnerable people are (i.e. those who are ‘food insecure’), where they live, how insecure they are, and why they are insecure. WFP bases its interventions on these results.

“If my job is not done properly, the most vulnerable people would not be identified and thus not assisted.”

How does he make sure his job is done properly?

“I learned most of my programming and database management skills through self-study and the material available on lynda.com,” says Jules, who studied information technology in school.

Code Clinic 6: Building Dynamic Websites

code clinic 6

When the Internet first made an appearance, it was nothing more than a collection of fixed web pages. Back then, web pages didn’t use external data to build the dynamic sites we now expect as a daily experience. Incorporating real-time data such as finance, weather, updates from friends or the status of a thermostat changed the Internet from a static library of reference materials into a busy highway of information.

Code Clinic Six challenges our authors to use their language of choice to merge data with a web page template.

We’re starting with files created by James Williamson for chapter nine of his Dreamweaver CC Essential Training course, but instead of manually inserting the data into the page, we’re using code to bring the data and the HTML together.
