Interpolated Strings

I have been stuck for about 45 minutes on this and I am probably not understanding the question correctly.

"In this task we're going to declare two strings. First, declare a constant named name and assign to it a String containing your name. Second, declare a constant named greeting. Set the value of greeting to an interpolated string that combines "Hi there, " with the string stored in the name constant. As an example, the final value of greeting could be "Hi there, Linda.". Note: Make sure to enter a period/full stop after your name in the final string."

I have tried the following but that seems to give an error in the Treehouse online system

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

Then I tried it differently using Xcode and that provided me with needed result

let name = "Michael." let greeting = "Hi there,"

let greetingName = "(greeting) (name)"

Please, advise

In swift you interpolate strings by using a slash and and two parentheses and then the variable name you want inserted in the string between those, like this:

"Hello there \(name)" // This places the contents of the name variable inside of the string.

So the solution looks like this:

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