10,893 PointsSwift Basics code challenge working in Xcode, but not Treehouse compiler. What am I doing wrong?
I'm in the Swift 2.0 Basics course, in the "Recap: Swift Types" section. On task 2 of 2 I'm getting the "Bummer" message which reads "The string literal being assigned to output must be an interpolated string that evaluates firstValue, secondValue and product"
Here's my code:
let firstValue = 500
let secondValue = 5
let product = firstValue * secondValue
let output = "\("The product of") \(firstValue) \("times") \(secondValue) \("is") \(product)"

Treehouse TeacherYou only need the backslash and parentheses around things that are a variable name to be interpreted. firstValue is a variable name. "The product of" is not a variable name. Take a look at the output line you need:
let output = "The product of \(firstValue) times \(secondValue) is \(product)"

10,893 PointsYESSS! Thank you so much! Not sure why it worked in Xcode, but I'm glad you taught me the proper syntax because I would'be been doing a lot of extra work for myself in the future. Thanks again!

Treehouse TeacherYou're quite welcome! And yes, it's good to get used to it now because this string interpolation stuff comes around in other languages too. I promise :)
