![]() ![]() The Apple coding app is free, but it requires an iPad, the company’s tablet computer, which has declining sales and which many schools and families may not be able to afford. Apple devices and ones based on the Microsoft Windows software have recently lost market share at United States public schools to Chromebooks, inexpensive laptops that run on the Google Chrome operating system. Tech companies are in heated competition for the education market. Cook, the chief executive of Apple, said during a company event last week to introduce the iPhone 7. “We believe every student should have the opportunity to code,” Timothy D. In January, President Obama said he was asking Congress to provide $4 billion in the budget for a computer science initiative in public schools. Tech executives have argued that such training could help address socio-economic differences among students, by providing them with marketable job skills. The introduction of Apple’s app coincides with a larger Silicon Valley campaign to press public schools to teach coding. “It’s easy to take the next step and learn to write a real app.” “When you learn to code with Swift Playgrounds, you are learning the same language used by professional developers,” Brian Croll, Apple’s vice president of product marketing, said in a telephone interview. Unlike some children’s apps, which employ drag-and-drop blocks to teach coding, the Apple program uses Swift, a professional programming language that the company introduced in 2014. ![]() if let bestPlayer = players.Apple plans to release a free coding education app on Tuesday that it developed with middle-school students in mind, in the latest salvo among technology companies to gain share in the education market and to nurture early product loyalty among children.Īpple’s app, called Swift Playgrounds, introduces basic computer programming concepts, like sequencing logic, by asking students to use word commands to move cartoon avatars through a fanciful, animated world. ![]() Use optionals when you might have an instance to return from a function, or you might not. Memory is managed automatically using tight, deterministic reference counting, keeping memory usage to a minimum without the overhead of garbage collection. To best support international languages and emoji, Strings are Unicode-correct and use a UTF-8 based encoding to optimize performance for a wide-variety of use cases. Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces. Even better, you don’t even need to type semi-colons. Named parameters are expressed in a clean syntax that makes APIs in Swift even easier to read and maintain. Swift is the result of the latest research on programming languages, combined with decades of experience building Apple platforms. ![]()
