Interpolation Challenge: Wrong here, correct in real world

Why was my answer to the Interpolation Challenge marked incorrect here, but works fine in Xcode?

let language = "Swift"
println("Learning \(language)")

I just successfully completed the challenge myself again using the below code:

let language = "Swift"
println("Learning \(language)")

Not sure what is going on because you have the correct answer.

I recommend looking closely at the error message when your code is marked wrong on here. They're usually pretty helpful.

Also, try typing out the code rather than copying it from another program - like from an Xcode playground - if that's what you're doing.

Thanks for your help guys!
