How do you compile the code, so that the Function of greeting reads "Hello Tom"

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).

Everytime I try to compile this code, "Tom" never shows up. How do I compile this code?

func greeting(person: String) {
    println("Hello " + "(person)")
greeting(" Tom")

instead of doing this:

println("Hello " + "(person)")

You need to put:

println("Hello \(person).")
