Stuck on FizzBuzz Question - Swift 2.0 Collections and Control Flow!

I'm not sure where I'm going wrong, compiler error I'm receiving in treehouse is:

swift_lint.swift:3:33: note: to match this opening '{' func fizzBuzz(n: Int) -> String {

When I run the code in Xcode I receive an error stating - "Will never be executed"

I feel like it something very simple and I am just not seeing it. Thanks for the help!

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
  for n in 1...100 {
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 "No Fizzing or Buzzing here!"
}
  // End code
  return "\(n)"
}

First, you started a for loop inside your function that's not needed, and which doesn't have a closing curly brace. If you check the instructions, it says "The challenge also does not need you to loop over a range of values (using for or while). I'll take care of that."

Second, the else... clause was supposed to return n as a String. The challenge editor is quick picky sometimes, and I'm sure that it wasn't happy with that either.

Here's the code, so you can compare:

func fizzBuzz(n: Int) -> String {

    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)"
    }
}
