Okay, now I get it, the naming makes autocomplete more convenient.
Returning void makes it easier to spot errors. If you accidentally use "capitalizeInPlace" instead of "capitalizedString" your code will compile without issues. If the mutating method returned void, it would result in a compile error.

That's an extreme edge case though, since if you're using a mutating method, you're using a mutating string, and you're probably aware of that.
