Modify the println statement within the greeting function to use the variable person. For example, if you pass a person named "Tom" to the function then it should display: Hello Tom. (Hint: you must use string interpolation).

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

Euuuh you did well the first task of the challenge but what you miss in the second task is the String interpolation with the parameter "person" and then you need to call the function and pass the String "Tom" inside. I hope you figured out and it helped you

          <p>func greeting(person: String) {
    println("Hello \(person)")
}

greeting("Tom")</p>
          ```
