I have no idea how to solve this. I've tried everything.

I'm sure I am making a fundamental mistake, please help me correct this.

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

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

So this task is basically 2 different tasks, the first one, where we need to declare that the output will be a String (and you did this correctly).

The second part asks you to change the print statement into a return statement. We do this by changing the keyword on the last line inside the function. No code will need to be outside the function here.

Let me know if this works.

Hello Andrew.

You are not supposed to print anything here, just make the function return the full string and you will be ok.

I don't know how to do that. What exactly am I supposed to write?

Hi Andrew, so in this challenge, the goal is to modify the function to return the string "Hello (person)" with the proper input string added in The way you have the function modified at the moment is close but is only returning the input string itself. There's no need to call the "println" method so don't worry about that. Let me know if that helps.
