That last line of code.

Use concatenation to combine the greeting string with a second string literal.

Example:

variable + " This is a string of text!"

Hi there,

Looking at your code I wanted to answer a question I had myself - can you or can you not interpolate an already interpolated string. The answer is yes, you can. I experimented writing some of my own code but yours as well. I think the editor was looking for the concatenation of your answer as Rich had mentioned, which is why it didn't accept. I hope this helps.

//My Experiment

    var interpolateOnce = "Get this string,"
        print(interpolateOnce)

    var interpolateTwice = "\(interpolateOnce) and this one too,"
        print(interpolateTwice)

    var interpolateThrice = "\(interpolateTwice) and this second to last one,"
        print(interpolateThrice)

    var interpolateFourTimes = "\(interpolateThrice) and this final one"
        print(interpolateFourTimes)


//Your Example

let name = "Johannes"
    print(name)

let greeting = "Hi there \(name)"
    print(greeting)

let finalGreeting = "\(greeting) How are you?"
    print(finalGreeting)

That's great!

Were either of the answers helpful? Was it a completely different issue? It would help others if you could elaborate on what you found or mark the appropriate answer best.
