Variables can be created in a playground—a prototyping area for quickly typing out code and getting feedback on whether the code is working properly.
- [Instructor] There are actually multiple ways you can…get started in writing your code.…One of the easiest, and most clean ways…to write code, just to practice how programming works…is through something called a playground.…So I'm going to create one from the welcome screen here.…If you're already in Xcode and are not at the welcome screen…you can just go to File, New, and then choose Playground,…or use the shortcut Option + Shift + Command + N.…So create a new playground and I'm going to give this a name…I'll call this Variables,…and for platform I'm going to choose iOS.…
For what we're doing it doesn't make a huge difference.…I'll hit next and then I'm going to save this…in my Exercise files, Chapter 02, Playground, Final…and of course if you're following along…save it right in here outside of that final folder.…I'll hit create.…And I'm going to expand my screen a little bit…so that all we have here is the playground.…So, here, what we have is three…lines of codes spread out over six lines.…So we have line one,…
