Do I need to double space whenever I'm writing code? Or is it just to make things clean?

Is it required or is it just preference?

Hey Evan,

Swift doesn't really care about whitespace, so yes, it is just a preference among most programmers. It just makes the code easier to read if you're skimming through it. Not everything is double-spaced, but that would be up to you. Group certain things... space out others. Basically whatever makes reading it easier. Imagine you wrote some code and then you go back to look at it months later... those spaces are going to be really nice. :)

Keep Coding! :dizzy:

Just like comments, spacing in general is not required but it allows for more neat and readable code.
