String interpolation is how you can display the value of a variable within a string.

So in your example you want to be able to display the variable person within a string.

println("Hello \(person)")

As you can see you have to use a backslash (this escapes it) and then wrap your variable name in parentheses in order to get it to display its value within the string.
