- [Instructor] When you're working in X code, creating a playground allows you to prototype code so you can have very little code on the screen and just focus on one little piece. And that's what we're going to do to get a little bit of practice in working with variables. So in X code, go to file, new, and then choose playground or use the keyboard shortcut. So I'll click that, and then what I'm going to do is choose iOS, blank, and then hit next. And I'm going to give this just the default name and save it on my desktop. So there's my playground and I'll go into full screen mode, and it has this greeting that says "Hello, playground". And if you hit this play button right here to the left of the code, so that's right over the line number, then the app will build for a second and launch, and it will show you the values of variables on the right side of the screen. So that's really helpful when you're learning and when you're trying to develop things like algorithms. The first time you…
