Help with fizzBuzz, all work in playground

I have been going crazy with this exercise. I have built 2 results for this and both work in a playground and give the appropriate results. I can not get them to work here, either. I can not also see any output when I switch to the preview. Any ideas? I will post the other version of the solution in a sperate comment

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
   for n in 1...100 {
    switch (n % 3, n % 5) {
    case (0 , 0): print("FizzBuzz")
    case (0 , _): print("Fizz")
    case (_ , 0): print("Buzz")
    default: print(n)
    }
}
    return "\(n)"

  // End code

}

here is my other solution, again, both work

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)
}
}

Hi Joseph If you look at the instructions it asked you to change print statements to return statements

func fizzBuzz(n: Int) -> String {
    // Enter your code between the two comment markers
    if (n % 3 == 0) && (n % 5 == 0) {
        return("FizzBuzz")
    } else if (n % 3 == 0) {
        return ("Fizz")
    } else if (n % 5 == 0) {
        return("Buzz")
    } else {
        return("n")
    }
    // End code
}
