I love that Swift Playgrounds allow us to explore programming tasks but I wish we could take the next steps and share what we've built with others. The ability to share is what makes a platform viral.

I'm writing about Functional Programming in Swift and other topics at my Editor's Cut blog. These posts may form the foundations of a book I'm working on. Join the Discussion.
