your code is similar for the code necessary for a different challenge. However the challenge you linked to is not that one. Did you get your code from another forum post perhaps? That code is for a tuples challenge, this challenge is on return types.

the challenge states Modify the definition of the function named greeting to return a String and replace the println statement with a return statement. The function should return a greeting. For example, if you pass in a string "Tom" then the return string would be: "Hello Tom".

the challenge initially has the following code:

func greeting(person: String) {
    println("Hello \(person)")
}

it needs to return a string, not a tuple. and you need to return the string, not print it

the swift eBook states:

You indicate the function’s return type with the return arrow -> (a hyphen followed by a right angle bracket), which is followed by the name of the type to return.

func greeting(person: String) -> String {
    return "Hello \(person)"
}
