Xcode 8.0 Playgrounds
Available today, these new standalone Swift 3.0 files are great for sharing and experimentation. Provided as a single download bundle, popular topics include: Big O Notation, Linked Lists, Binary Search Trees, Graphs, Queues and others.
Originally introduced with Xcode 6.0, Playgrounds work as standalone Xcode files. Great for learning new topics, folks can get up and running without expert knowledge of Xcode or version control management. As with the supporting book, the Xcode 8.0 Playground series will be updated as Swift 3.0 evolves.
