The updated app includes a new "What's Next" feature that offers up other playground suggestions to try based on current progress in the Swift Playgrounds app, providing users with a clearer path for learning new coding skills.
Today's update also introduces support for macOS content caching in order to speed up downloads in networks that have multiple Swift Playgrounds users.
Swift Playgrounds 2.1 comes three months after Apple introduced version 2.0 of Swift Playgrounds, an update that added support for subscribing to playgrounds from third-party creators and browsing and downloading third-party content.
The 2.0 update also brought support for robots like IBM's TJbBot and Mekamon, and a new gallery view was added to make it easier to see all available playgrounds you're subscribed to.
Swift Playgrounds can be downloaded from the App Store for free. [Direct Link]
