在安静的世界里编织精彩

Swift Playground makes it fun to learn to code and build real apps. You solve interactive puzzles in the guided “Get Started with Code” and learn the basics of building apps in “Get Started with Apps.” You experiment with a wide range of challenges and samples that let you explore unique coding experiences.

Swift Playground doesn’t require any coding experience — it’s perfect for anyone just starting out, from eight to one-hundred-and-eight. The whole time you are learning Swift and SwiftUI, the powerful programming technologies created by Apple and used by professionals around the globe to build many of today’s most popular apps. And because it’s built to take advantage of real frameworks, Swift Playground provides a one of a kind learning experience.
