I get paid to write Swift code at the day job, at night I write a lot of node backend code for a side project. I have to say that it's pretty refreshing to jump in and not have the (increasingly) opinionated Swift compiler barking at me for everything I do. Unfortunately Swift has also made me extremely paranoid in JS, where I find that everything I write is checked for null, but I don't think I'd trade the freedom in nodeJS for Swift's type safety. This is super cool though, well done.
