How do I go about making sure a constant has an interpolated string value?

I don't understand how to go about assigning the constant (in this case "greeting") to the interpolated string. I declared the the constant "greeting" and gave it a string value of "Hi there" but I can't seem to figure out how to use the interpolated sting method to display the values from "name" and "greeting" constants.

strings.swift 
// Enter your code below

let name = "bob."

let greeting = "Hi there"

let interpolatedGreeting = "\(greeting), \(name)"

Task 1:

let name = "bob"

let greeting = "Hi there, \(name)."

They didn't want you to create a third constant. They just wanted you to interpolate name into greeting. Also, the editor is very picky, so you have to put the period in the right place. Not in name, but at the end of the String in greeting.

For Task 2 you will add:

let finalGreeting = "Hi there, " + name + ". How are you?"

So, at the end, you have an example of String interpolation and an example of String concatenation.

You have to do the string interpolation in the greeting constant:

let name = "bob"

let greeting = "Hi there, \(name)."
