***Im having issues with interpolation problem...It wont accept my code....I run it in XCode and everything works fine..

By the code you can infer what the question is about...

let secondValue = 30

let product = firstValue * secondValue

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

I think you're having a little bit of trouble with the idea of string interpolation! The beauty of interpolation is that we can blend variables and constants with strings and numbers. Let's see interpolation in action:

let numberOfApples = 6
let numberOfOranges = 7
var message = "I had an amazing harvest today! I picked up \(numberOfApples) apples and \(numberOfOranges) oranges. In total, I had \(numberOfApples + numberOfOranges) pieces of fruit!"

In interpolation, we use the 

\()

to signify a variable, expression, constant, or anything like that. What you might want to do is use these ideas to come up with your own solution. One more example:

let firstMultiplier = 40
let secondMultiplier = 50
let answer = "\(firstMultiplier) times \(secondMultiplier) is \(firstMultiplier * secondMultiplier)"

I hope that helps you!
