Hey Yasser,

in this challenge you have to use string interpolation which means that you have to print "Learning Swift" by interpolating the constant language that contains "Swift". The constant already exists so you shouldn't remove it and you don't have to create it yourself. The only thing you have to do is write the println statement and print out the string with "Learning" and the interpolated constant. You interpolate a constant/variable by writing it inside of \() .

It should look like this then:

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

I hope that helps, good luck! :)

Hi Yasser,

The challenge wants you to use string interpolation to complete the string "Learning Swift" with the existing constant language. Strings can be interpolated by surrounding the name in backets and preceding those with a backslash. This inserts the contents of the constant or variable into the string being used. Something like this:

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

So, language holds "Swift" and we insert the contents of language with the brackets and backslash. The output string will be "Learning Swift".

Make sense?

Steve.
