In my earlier I post I talked about not being very sure that a method I wrote for one of the Stanford iOS Programming course assignments was really embracing Swift as a language. I then posted about using Swift’s unit test framework that would make any refactoring easier and better.
And so on to the refactoring…
Well, with a fresh day came a fresh eye, and there was not too much I could really do to make the method more Swift than C/C++. I ended up mainly folding some let statements into inline expressions. Not exactly hard, but when all was completed I think the code is more or less as tight as it could be and still easily readable – opinions to the contrary are very welcome.
