I have the right answer (I think) but it still says that its wrong.

Question: Given the constant named language, write a println statement which will print the following string: "Learning Swift".

Use the language constant within the string you pass to your println statement. Practice using string interpolation.

Answer: let language = "Swift" println ("Learning(language)")

Result: Bummer! You printed "Learning Swift", but you were supposed to print "Learning Swift".

In essence.. I have the answer right but treehouse just doesn't care? :/

Hey alexander Leavell,

You're VERY close. You're just missing one character. What you're looking to do is use string interpolation to add the value stored inside a constant or variable to another string. The syntax for this is \(variable).

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

I also recommend that you Switch to the iOS Swift 2.0 Development track. The Swift language is on version 2.0 now and there have been some changes. For example, println() is no longer supported. It has been changed to print(). So, if you're using println(), you will get an error.

The new track has accounted for these changes. You can find it here: Swift 2.0

Good Luck!
