I don't understand the question about interpolation using constants.
I don't understand what its asking me to do and i cant find the info in the video.
println language = ("Learning Swift")

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! :)
