FizzBuzz Challenge could be far more educational

The FizzBuzz can be solved with a simple set of variables and an if/else if statement:

func fizzBuzz(n: Int) -> String {
  var fizz = n % 3 == 0
  var buzz = n % 5 == 0
  let fb = fizz && buzz
  if fb {
    return "FizzBuzz"
  } else if fizz && !buzz {
    return "Fizz"
  } else if !fizz && buzz {
    return "Buzz"
  }
  return "\(n)"
}

Unfortunately, this doesn't take advantage of any of the other useful conditional and check statements we've learned.

I've coming from a strong JS background, so I immediately looked at this and said, "It's way too easy, ", we could be using for, switch and arrays to solve this but the challenge itself has none of those requirements.

I would suggest adding the caveat that the numbers checked need to be in a certain range and that we need to check against them before returning the value or Fizz/Buzz/FizzBuzz.

For example, simply adding the requirement that the range be 1 - 100 would require the use of the range operator and probably a for statement.

Adding an additional requirement that the numbers be stored in an array would incorporate the append method.

These concepts were easy for me to grasp coming from JS, but would be much more challenging for a person not familiar; it is far more educational to be challenged to combine all of these problem solving methods rather than a simple if/else statement.
