TestFlight users who have signed up to beta test Apple's Swift Playgrounds coding app can now download the Swift Playgrounds 3.0 Beta, which is available as of this morning. Swift Playgrounds uses Swift 5.0, the beta version of Apple's coding language.
The full extent of what's new in Swift Playgrounds 3.0 isn't clear as of yet, but Apple's release notes for the beta update provide a bit of detail. The new version of the app allows Playground Books to contain directories of Swift code and resources that can be imported for use by any page in the book.
Modules in a book's Modules directory can also be imported to any page in the book. Apple's release notes for the update are below:
New in Swift Playgrounds 3.0 Beta:
Playground Books can now contain directories of Swift code and resources that can be imported for use by any page in that book.
The ./Contents/UserModules/UserCode.playgroundmodule/Sources/UserSource.swift file is editable by users using the new source editor tab.
In addition, the modules in a book's Modules directory (.playgroundbook/Contents/Modules) can be imported by any page in the book, but can't be viewed or edited in the app.
Note: Swift Playgrounds 3.0 beta uses Swift 5 (swiftlang-1001.0.63.8). Code written using other versions of Swift may not work in UserModuleExample.playgroundbook.

This is the first beta of Swift Playgrounds 3.0 that Apple has released. The current version of the app available to the public is version 2.2, released back in November.
