Modify the println statement within the greeting function to use the variable person. For example, if you pass a person

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). i don't understand

parameters.swift
func greeting(person: String) {
let
    println("Hello")
}

To print the person name, you have to add the parameter "person" into the print function.

One way to do that is via string interpolation like this.

func greeting(person: String) {
    println("Hello \(person)") // note the syntax on how to pass the person name into the string
}

If you test the above in the playground, you will see that this works.

I hope that helps,

Mike
