We have tried to cover as much of Swift to get started with coding as possible. A single chapter would not do justice to cover the breadth of this topic. We saw that we can use the println function to output our data, and while in the Playground, the values for all variables are seen in the editor space. In the next chapter, we will take a break from code and look at creating interfaces visually in Interface Builder. If you want to learn more about Swift, Apple has a blog and lots of resources including some free iBooks on Swift. One thing to note is that Swift is evolving, and in the time since Swift was announced at WWDC to the time it was released in September, the language and the syntax has undergone many changes. The possibility of it changing in the near future cannot be ruled out. So be aware of this fact when working with Swift.
