I copy&pasted this code from the playground in here.
// Enter your code below
let name = "Andy"
let greeting = "Hi there, \(name)."
let finalGreeting = "\(greeting) How are you?"

To concatenate two strings you have to use the + operator on them. Like this:
let finalGreeting = greeting + " How are you?" // Concatenate greeting to " How are you?"
Concatenation and interpolation will result in the same string, but they are different techniques. Both of them are pretty commonly used which is why the challenge wants to ensure you are familiar with them.

28,558 PointsNah this is a very common task for students to have trouble with, so you don't have to feel too bad .
Since the techniques produce the same string they are often treated as interchangeable (and generally they are) so having a challenge that rejects code just based on the technique used to combine the strings is somewhat harsh.

5,471 Pointsthat´s what I had problems with the first time that I tried teaching myself code... I still prefer this interactive method over other courses that I can just follow along via video, so I´ll keep on trying :)
