Apple has released version 2.0 of the Swift Playgrounds iPad app. The app provides an interactive learning environment for the Swift programming language. With version 2.0, Apple has introduced subscriptions to playgrounds from third-party creators. According to Apple’s developer news site:
You’ll automatically see new and updated playgrounds in your subscriptions, a content gallery that shows all playgrounds in a single view, new robots, and much more.
Subscriptions can be added by entering a URL or by browsing a gallery Apple has created, both of which are accessible from an ‘Add Subscription’ button in the top right-hand corner of the screen from which you add new playgrounds. As of publication, the buttons for adding subscriptions from the gallery do not work, but they should soon. When updated playgrounds are available, you can receive a notification too. Among the first third parties with subscription-based playgrounds are Sphero, Lego Mindstorms, UBTech, Parrot Drones, IBM, Mekamon, Wonder Workshop, and Skoog.
In addition to subscriptions, the update includes enhanced documentation for the Swift programming language and iOS SDK, and playgrounds can be opened from the Locations button in the Files app.
