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

1 Answer

Everything's good up to the modifying the function. What they want is when the function is called with a name (like "Tom") it will display "Hello Tom". So you have to modify the println() statement:

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