Hey Mark,

firstly you shouldn't change the language constant, you can just leave it as it is. To print out "Learning Swift" with the println function and string interpolation you can write the String "Learning " and then inside of the string you can interpolate the constant language by writing it inside of \() . Also just a note by the way: In Swift 2 you have to use the print function instead of println .

The solution for this challenge could look like this:

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

I hope that helps, good luck! :)
