Help - can’t get through this println code challenge !

Given the constant named language, write a println statement which will print the following string: "Learning Swift". (Remember to use the language constant within the string you pass to your println statement).

println.swift 
let language = "Swift"
println("language" + learning Swift)

Hi,

They want you to print the constant called language and add a string "Learning" in front of it.

If you want to print a constant or variable, we use syntax which looks like this: 

println("\(language)")

This will print only the constant so the output will look like this: Swift

We want the output to be: Learning Swift

The final syntax is:

println("Learning \(language)")

I hope this will help :)

This is correct, although the code from the OP would work, I believe they want you to use string interpolation instead of concatenation.

Concatenation 

println("Learning " + language)

Interpolation

println("Learning \(language)")

Good luck :)
