What We’ve Learned

In this chapter, we’ve tooled up for our journey into iOS 10 development, and we’ve gotten a tiny taste of how it works. We downloaded and installed Xcode 8, which is what we’ll use to create our apps.

Since we’ll be writing our apps with the Swift programming language, we created a playground to try out some simple Swift code in an interactive sandbox, which lets us type in a little code and see what happens. The playground gives us access to most of the things we could do with the iOS SDK, from crunching numbers to playing web radio. And with so much to play with in the SDK, we looked at how the documentation viewer lets us browse or search the documentation for classes, methods, and functions that we can call.

Our next step will be to get a real grip on the Swift programming language so we can start building more sophisticated behavior.
