Concatenated strings in Swift 2, works in Xcode, but not correct in quiz.

The attached code works in Xcode, but is marked as incorrect in the quiz.

Hi Jordan

The code isn't attached - but here is how the answer should look:

let name: String = "Marina"
let greeting = "Hi there, \(name)."
let finalGreeting = greeting + "How are you?"

Maybe you misspelled something?

Hi Marina,

Thanks for your help, sorry for not attaching the code I thought it would be done automatically. The question I am having trouble with is this one:

Often when we use apps, we enter our name during the sign up process. Later, inside the app, we see many greetings that reference us by name.

This feature can be implemented quite simply using string interpolation. 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.

The answer I gave is the following:

let firstValue = 100
let secondValue = 300

let product = firstValue * secondValue

let output = "The product of \(firstValue) times \(secondValue) is \(product)"

I get the correct output in Xcode, but not in the quiz. I can't figure out what I am doing wrong. Thanks again.

So, I'm thinking you attached the wrong code, since that doesn't look like anything from this challenge :-) Try to attach the right one, then I will take a look.

Hi,

So even though this thread is from quite awhile ago, I thought I'd jump in and clarity the correct response.

Marina your code is almost correct, only due to the challenging asking for a concatenated string, you would need to include " " to provide the appropriate whitespace between the two sentences. Thus you final code would be:

let finalGreeting = greeting + " " + "How are you?"

This is correct

let name = "Lynn" let greeting = "Hi there, (name)"
