Developing Code for OSX rather than IOS
I have just started to work my way through this book and have stumbled at the first hurdle. I wish to develop code for OSX. I have started a new project and chosen Cocoa Application as my template. I have entered the code [println("Hello Swift")] which gives an error 'Use of unresolved identifier "println"'.
Help please. Do I need to include a library? If so, which and how? Or something else?
