Bummer! Make sure the value you are assigning to greeting is an interpolated string

Works in Xcode preview, but can't get past this in the code challenge?

strings.swift 
// Enter your code below
let name = "Scott Becker."
let greeting = "Hi there"
let interpolatedGreeting = "\(greeting), \(name)"

Hi Scott,

You've done task 1 correctly. The second task wants an interpolated string saying "Hi there, name" - you need to merge the task one constant into that.

The last part wants a constant called finalGreeting - you've called yours differently - and it should be a concatenation of greeting and a string, "How are you?" (Ignore the leading space - that's a little error!).

You end up with:

let name = "Steve"
let greeting = "Hi there, \(name)"
let finalGreeting = greeting + "How are you?"

Make sense?

Steve.

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

It's expected to be in this form. What you're doing wrong is that you need to let greeting equal "Hi there, Scott Becker." Not interpolatedGreeting = If you read the instructions very carefully, you'll see that's what it says.

that might be a step after the challenge I was taking, as I don't remember that string being gone over - let finalGreeting = greeting +

But I'll poke around some more to see if I can GET to that step :-)

Thanks!

Hi Scott,

Top right of this window is the "View challenge" button - this takes you to the challenge the forum post was made from. That's where I got this from, anyway.

This one: https://teamtreehouse.com/library/swift-20-basics/swift-types/string-manipulation

Either way, I hope you get it sorted - if not, just shout!

Steve.

Thanks Samrat. I'm getting used to the semantics of designing with language as opposed to pixels. I appreciate all the help!
