i'm using let greeting = "Tom" which works in xcode but no on the test?

here's the code i gave it.

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

let greeting = "Tom" println("Hello (greeting)")

returns.swift 
func greeting(person: String) -> String{
    return person
}

let greeting = "Tom"
println("Hello \(greeting)")

OK - so you've modified the function to return a string, then changed the println a little too much. The println's string was the string you want to return. So the modified function looks like:

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

And that's it! If this method were used, it would be called in this way:

var varName = greeting("Tom")

The variable varName would then contain "Hello Tom". But that's not part of this challenge - it just wanted you to amend the method.

Make sense?

Steve.
