So let's go ahead and start Xcode, and go ahead and say New, Playground. And you can see that you can also create a playground for macOS, so that's what I'm gonna select, instead of the iOS, so go ahead and select macOS, and then just select a blank, empty playground. I'm going to call this Blockchain, and I'm going to put it in a lecture. Let's go ahead and, over here. Okay, so there we go. So we have a playground macOS, and currently…
