Having trouble w/ the println function. Not sure what I'm doing wrong. interpolate?

not sure what I'm doing wrong. Already confused....I think this lesson should be project influenced learning....For first timers, it's confusing as hell to know why we are doing things....the exercise should have a higher purpose. Also is the println function a literal command that is for a printer or just code to view in a console?

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

So to answer your question, yes, the print or println function is used in programming languages to print to the console. This allows you to see what your code is calculating or print text to the screen. Otherwise the computer would just do calculations without displaying anything.

In your answer, you printed "Learning Swift Swift" instead of "Learning Swift". 

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

thx! so the print function is just to display the output to a console? (and a console is your form factor display or just referring to the Xcode console?)

Yes, exactly. The console we're talking about xcode console in this case, which just appears on the bottom center in the main Xcode app, or in a separate partition on the right if you are in an Xcode playground.
