Unit 2: Introduction to UIKit|Introduction to UIKit

In the last unit, you got started with the basics of the Swift programming language and the basics of the Xcode development environment. You learned about constants, variables, types, operators, and control flow—and you had a chance to experiment with some Xcode features.

This unit will take you many steps further. You'll learn about structures, collections, loops, and different ways to work with the information that makes up an app. At the end of the unit, you'll build an ambitious project. Don't worry if it feels hard—because it is! Every coder in the world went through the same challenges. Keep at it, and you'll start to enjoy solving problems with code.

What You'll Build

Apple Pie is a simple word-guessing game, where the user must guess a word, letter by letter, before all the apples fall off of the apple tree. If there are apples remaining, the user wins—and can eat delicious Apple Pie.
