Swift 5 Frozen Enums
If’s funny how the blog posts in the community are often influenced by what we’re working on every day and with so many people starting to move their code to Swift 5, I guess it’s not surprising that this week, has seen a number of posts from different people on Swift 5’s changes to enums.

Great work from everyone involved!

nef
This week we also saw the release of Nef – a new framework from @tomasruizlopez and the team at @47deg. Nef is focused on closing the gap between your code and documentation, and consists of set of command line tools that lets you automatically generate your documentation from your example code and markdown docs written in a Swift Playground. Looks useful.
