iOS Swift Collections and Control Flow Control Flow With Conditional Statements Solution to FizzBuzz

Not a question; just a comment.

If you're trying to solve FizzBuzz using a switch statement, go ahead and read the relevant portion of "The Swift Programming Language (Swift 4)" (i.e., the documentation). You'll only need to read the first four or five paragraphs under Language Reference > Statements > Switch Statement. Cheers.
