Apple Swift - What is?



Swift is a new object-oriented programming language for iOS and OS X development. Swift is modern, powerful, expressive, and easy to use.

  • Fast. Compiles and optimizes with the advanced code analysis in LLVM to create high-performance apps.
  • Complete platform. Access all of the Cocoa and Cocoa Touch frameworks with Swift.
  • Safe by design. Eliminate huge categories of bugs, crashes, and security holes.
    Swift pairs increased type safety with type inference, restricts direct access to pointers, and automatically manages memory using ARC, making it easy for you to use Swift and create secure, stable software. Other language safety related features include mandatory variables initialization, automatic bounds checking to prevent overflows, conditionals break by default, and elimination of pointers to direct memory by default.
  • Modern. Write, debug, and maintain less code, with an easy to write and read syntax, and no headers to maintain.
    Swift includes optionals, generics, closures, tuples, and other modern language features. Inspired by and improving upon Objective-C, Swift code feels natural to read and write.
  • Interactive. Use Swift interactively to experiment with your ideas and see instant results.
  • Unified. A complete replacement for both the C and Objective-C languages. Swift provides full object-oriented features, and includes low-level language primitives such as types, flow control, and operators.
For full information about the Swift language and to get started using it, see The Swift Programming Language.

8 affordable tools to help optimize for conversion and understand your users better

Image
Conversion rate optimization (CRO) has remained a hot topic over the last few years, and more companies are starting to allocate larger proportions of their budget to optimize their websites for existing users rather than focusing solely on customer acquisition. Over the last few weeks I’ve been involved in a lot of CRO-focused projects, both in my day job and on some of my side projects – so I thought I’d focus my first TNW article on some of the tools that I’ve used and found particularly useful. The following tools are designed to either aid the CRO process or help to deliver insight into the performance of your website. Optimizely Via About Analytics Optimizely is an A/B testing tool (amongst many other things) that allows you to quickly and easily perform experiments on content and pages of your website. I really like Optimizely because it makes it very quick and easy to create complex experiments and apply them to either all of your visitors or individually specified sub...

Faraday wants you to believe it’s not a front for the Apple Car, but probably is

Image
Billion dollar car companies don’t pop up overnight. Well, except Apple   Faraday . It plans to release its first vehicle in 2017, and claims it’ll have  15 percent more range  than the Tesla Model S. Bold. It’s also spending some serious loot. According to a recent  blog post , Apple  Faraday plans to spend $1 billion to develop a manufacturing plant in California, Nevada, Georgia or Louisiana in order to “explore other aspects of the automotive and technology industries, including unique ownership and usage models, in-vehicle content and autonomous driving.” The well-funded startup currently employs 400 people and adds 10 new hires a week. Right now you’ll find them operating out of Nissan’s former California research facility. All that sounds great, but where Apple  Faraday loses the rest of us — and sparks intense rumor that this could indeed be the Apple car —  is through its representative speaking in vague generalities and carefully guarded trui...

The new Xbox One Elite comes with a 1TB SSHD and Elite controller

Image
The all-new  Xbox One Elite Console , announced today, is for the most serious console gamers out there. It features a 1TB solid state hybrid hard drive and the new customizable Elite controller for $499 in the US. Microsoft says the new SSHD hard drive means you’ll get into games 20 percent faster than the original Xbox One console and it automatically optimizes games and apps to open faster. The  Elite controller  allows gamers to customize the thumbsticks, directional pad and paddles for gamers to get the controller to their liking. As for the console itself, it doesn’t appear to be visually any different than the previous version of the Xbox One and the only internal difference appears to be the slightly speedier hard drive. Microsoft  also  announced a new ‘ lunar white ‘ version of the Xbox One controller which adds ‘improved grip texture’ and comes in white and gold for $64.99. Xbox One Elite will be on sale in the US starting November 3. You can...
