As a computer programmer, I live in a familiar cycle: Write some code, then run it repeatedly to work out all the kinks. There is a moment when you hit “run” for the first time, already anticipating what the errors might be, thinking about next steps when the error inevitably presents itself.
It’s been weird writing server-side Swift. I do my hacking, adding a feature or refactoring or whatever, I make the compiler happy, then it’s time to get to the nitty-gritty. I roll up my sleeves, start the program… and it works. Just like that. I run the tests against the other systems. It works.
It’s like you’re all ready for a fight and the other guy doesn’t show up. NOW what are you going to do?
Swift can be annoying with how hard-assed it is about certain things, but that picky compiler that sometimes forces long-winded syntax is like that really picky English teacher who you realize after the fact gave you a command of words you didn’t have before. If you have a null pointer in Swift, you went out of your way to create it.
Programming languages exist for the convenience of humans, not machines. So if you can make a language that makes it harder for humans to make a mistake, why wouldn’t you?
Man I enjoy writing code in Swift. Of the four languages I use regularly, Swift is hands-down the one I’m most productive with, even though I’ve been using the others for far longer. And just today I remembered that functions could return tuples, and I was like, “Damn!” all over again, thinking how I can shrink my interfaces.
Most of my days are consumed writing code in other languages (at least for now), and what strikes me every day is that the mistakes I make would not have been possible in Swift. Think of that!
