iOS Swift Basics (retired) Control Flow Exercise: FizzBuzz Generator

The exact SAME code for my "if-conditional" sometimes WORKS, and sometimes DOESN'T work.

I was thinking of an alternative implementation for the FizzBuzz game, so I chose the C-style "for-iterator" and an "if-conditional".

Strangely enough, the code didn't work. So I rewrote the two "else if" statement, and voilà, it worked. The exact same code.

Then I pasted the old code over it, and even though nothing changed, it threw up 3 errors.

One works, one doesn't. What the hell?!

Hey there, so I could be wrong about this, but using the style I found in this control flow example from apple:

https://teamtreehouse.com/forum/the-exact-same-code-for-my-ifconditional-sometimes-works-and-sometimes-doesnt-work

it looks like swift likes you to start the else if statements on the same line as the end bracket for the previous control flow operator (if or else if). I could be wrong but in my experience xcode is pretty finicky about how you style/space things.
