Your code has the right approach, but the main part is missing. First you can omit the println() statement, since you don't won't to print out the greeting directly. Second you have do return the greeting instead of printing it out.

A working solution could be like this:

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

or if you want to assign the greeting to a constant first:

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