I write a lot of Go and used to write a lot of Swift. Swift is what you’ll consider a modern language (optionals, generics, strong focus on value types), while Go is Go. I appreciate both languages, and of course Swift feels like what you’d pick any day. But, after using both nearly side by side and comparing the experience directly, I’ve got to say, I’m so much more productive in Go, there’s SO much less mental burden when writing the code, — and it does not result in more bugs or other sorts of problems. Thing is, I, of course, am always thinking about types, nullability and the like. The mental type model is pretty rich. But the more intricacies of it that I have to explain to the compiler, the more drag I feel on getting things shipped. And because Go is so simple, idiomatic, and basically things are generally as I expect them to be, maintenance is not an issue either. Yes, occasionally you are left wondering if a particular field can or cannot be nil / invalid-zero-value, but those cases are few enough to not become a problem. |
