No sure how to get "Hello" to show up in my return statement.

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

Hi there,

You're nearly there.

The challenge is expecting the return to be "Hello <person's name>".

For this you've correctly amended the method skeleton to include a String being returned and replace the print with a return. But you do need to keep the string interpolation in there:

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

Using that method would look like greeting("Steve") which would then return a string, Hello Steve to where the method was called from.

Hope that makes sense!
