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

Copy/Paste error message here, not sure what is the error:

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

println.swift 
let language = "Swift"
var zstr : String = "Learning "
println("\(zstr) \(language)")

The editor can be rather picky sometimes, and the error messages baffling, as in your case. But here's what it wants:

let language = "Swift"

println("Learning \(language)")

Your way works in Xcode, but not in the editor.

Actually I didn't try it in Xcode but either way, I figured out the correct answer.. just worth mentioning to you guys.

You don't have to use the 2nd variable, but when you do, you put in a 2nd space, which isn't supposed to be there. This code worked for me:

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

However, if you wanna do it with 2 variables, you just need to have to remove the space at the end of the 2nd variable, like this:

let language = "Swift"
// Notice the lack of a space at the end of this line
var zstr : String = "Learning"
println("\(zstr) \(language)")
