Hey Robert,

you have given the language constant already, so everything you have to do is use println to print out a string in which you interpolate the constant language. To interpolate a variable/constant inside of a string just write the variable or constant inside of \() .

So you should write it like that:

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

I hope that helps and if you have further questions feel free to ask! :)

Thanks very much!!
