The NHS is preparing to close nearly all of its Open Source repositories. Throughout my time working for the UK Government - in GDS, NHSX, i.AI, and others - I championed Open Source. I spoke to dozens of departments about it, wrote guidance still in use today, and briefed Ministers on why it was so important. That's why I'm beyond disappointed at recent moves from NHS England to backtrack on…

Roadmap for improving the type checker In the past, we've released various "manifestos" and "roadmaps" to discuss planned improvements to the language. This post is also a roadmap of sorts, but instead, the focus is on the implementation rather than user-visible language changes (however, I will briefly mention a few potential language changes at the very end). Specifically, I'm going to talk about some work we are doing to improve expression type checking in the Swift compiler. This includes c...

Nearly ten years ago, Swift was open sourced and an official runtime for Linux was released. I’ve been involved with Swift on the server since almost the very beginning, originally picking it up as a way to use a language I really enjoyed for backend development. In that time Swift has come a long way, with stability across platforms, a burgeoning ecosystem and many success stories. It’s matured into a great option for highly-scalable server applications, websites, and lambdas. In this post, I’ll cover how Swift:
