Yesterday, Apple released Swift Playgrounds 4.0, the first version of the app from which you can build an app and publish it on the App Store. That’s a big step forward for the app that started as a limited sandbox for learning to code. The app is not as capable as Xcode. Still, with support for Swift 5.5, live previewing of the app you’re building as you code, multiwindowing, access to SwiftUI, UIKit, the ability to move projects between Swift Playgrounds and Xcode, and more, the app has an enormous amount of potential waiting to be tapped.
Swift Playgrounds has steadily improved since its introduction in 2016 on the iPad and launch on the Mac last year. Early versions of the app were firmly grounded in learning to code. That’s still the case. The app includes an extensive catalog of lessons on how to code and build apps. There’s also a new ‘Get Started with Apps’ lesson and an App Gallery section that includes several sample apps to help teach coding basics.
