31,603 PointsHey Amaury,
the problem in your code is that you're trying to interpolate the string itself here:
\(Hi there)
"Hi there" is no variable (and wouldn't be a valid name for one), so you don't have to interpolate it and you can just write the string. Also note that even though it works like this it would be better and cleaner code when you write the period in the greeting instead of in your name constant like so:
let name = "Christian"
let greeting = "Hi there, \(name)."
I hope you understand what was wrong in your code now and that I could help you, good luck! :)

31,603 PointsHey Matthew,
there are a few things wrong in your code. You're using string concatenation instead of interpolation, to interpolate a variable or constant in a string you have to write the variable/constant inside of \()
. Also note that you can't write spaces between words in a constant/variable name like you did in "interpolated address".
So if you're interpolating your name in the greeting constant you do it like that:
// Enter your code below
let name = "Matthew"
let greeting = "Hi there, \(name)."
I hope that helps! :)

let name = "Christian."
let greeting = "\(Hi there), \(name)"
which it was wrong.
Thank you, Tobias Helmrich !!! Amaury.
