I chuckled more than I should at this passive aggressive *comment on RubyGems

Having an "unimplemented" helper function in Swift is handy for staying in a development flow state. Here's a post that shows how to build this 3 line function and hopefully inspire other productivty hacks. paul-samuels.com/blog/2021/03/2…

When you annotate an import with testable in Swift you are making subtle tradeoffs that may be impacting your design without you realising it. I've written a post to cover a few of these impacts. paul-samuels.com/blog/2021/03/2…
