Apple has introduced Swift Playgrounds, a new app for iPad that makes learning to code fun and easy for anyone. Swift Playgrounds brings coding to life with an interactive interface that encourages students and beginners to explore working with Swift, the easy-to-learn programming language from Apple used by professional developers to create world-class apps. Swift Playgrounds includes Apple-developed programming lessons where students write code to guide onscreen characters through an immersive graphical world, solving puzzles and mastering challenges as they learn core coding concepts. The app also features built-in templates to encourage users to express their creativity and create real programs that can be shared with friends using Mail or Messages or even posted to the web.
The library of Apple-developed programming lessons helps students learn core coding concepts, such as issuing commands, creating functions, performing loops and using conditional code and variables, and allows them to progressively build confidence and skill. Apple will regularly release new standalone challenges so students can continue to refine their coding abilities as their skills and interests grow. Educators and developers can also use Xcode to create their own unique challenges for the app.
In addition to the lessons, Swift Playgrounds comes with a number of built-in templates to help aspiring developers express their creativity. Students and developers can modify and build on this code to make it their own by adding graphics and touch interactions. Swift Playgrounds allows you to create a virtually unlimited variety of interactive programs using Swift and the iOS frameworks. You can create empty playground documents or start from one of the built-in templates with scaffolding for graphics and user interface to build powerful apps that respond to touch and accelerometer or that control Bluetooth devices. And since Swift Playgrounds uses real Swift code, projects can be exported directly to Xcode to create programs for iOS and macOS that can ultimately be turned into full-fledged apps.
Because Swift Playgrounds was designed from the ground up for the Multi-Touch iPad interface, you can create entire programs with only a few taps. A new coding keyboard lets you quickly type additional characters common to Swift programming by swiping across the key, while a shortcut bar presents the most likely next commands or values based on context. And, using a pop-over keypad, you can simply tap to edit a number in place, touch a colour value to display a colour picker, and even drag the boundaries of a loop or function definition to wrap around existing code. You can also drag from a library of common coding snippets to create new, powerful code with little or no typing. Your programs look beautiful running in full screen on the iPad Retina display and feel completely immersive, responding to touch gestures and the iPad accelerometer for interaction.
