Not sure what is wrong. It works in Xcode

My code is working correctly in Xcode. What am I missing here.

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {

  for i in 1...100 {
    if (i % 3 == 0) && (i % 5 == 0) {
        print("FizzBuzz")
    } else if (i % 3 == 0) {
        print("Fizz")
    } else if (i % 5 == 0) {
        print("Buzz")
    } else { print(i)
  }
}
  return "\(n)"
}

You didn't follow the instructions:

1) Change your variable/constant name that you are checking in each step to n. You have i.

2) Change all your print statements to return statements. You have print statements

3) Do not worry about the default case. You have an else statement.

4) The challenge also does not need you to loop over a range of values. You have for i in 1...100.
