Having trouble with function/ returning value

Modify the definition of the function named greeting to return a String and replace the println statement with a return statement. The function should return a greeting. For example, if you pass in a string "Tom" then the return string would be: "Hello Tom".

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

you need to add a string in the parameter when you call your function.

greeting("Some String")
