Your First Programming Language. In this course, you’ll begin learning Swift, Apple's programming language for building iOS applications. You'll start with fundamentals and work your way towards understanding all the core principles necessary to get started creating your first app. At the end of the course, you'll complete a problem set of exercises designed to challenge your understanding of Swift and give you the opportunity to apply what you've learned.

The beginning of any developer's journey is to learn their first programming language. For iOS developers, that journey begins with the Swift programming language. By taking this course, you will learn the basics of Swift and its core features which allow developers to solve problems, construct algorithms, and eventually build feature-rich mobile applications.
What You Will Learn
Lesson 1
Variables
In this lesson you’ll learn about one of the most basic building blocks of nearly every programming language — variables. Variables give developers the ability to store information that can be used to control the behavior of an application. By the end of this lesson you'll be able to create and store values using variables.
Lesson 2
Strings
In this lesson you’ll learn how to represent a sequence of characters or in other words a string! For iOS apps you'll use strings for labels buttons and any text in a user interface but you'll also need them for behind-the-scenes processing. By the end of this lesson you'll be able to create and manipulate strings using their powerful built-in features.
Lesson 3
If Statements
In this lesson you’ll learn how to control when and how Swift code is executed by using if statements. You'll also learn about the counterpart to if statements called "else" statements. By the end of this lesson
you'll be able to specify conditions for when Swift code should be executed based on logic that you define.
Lesson 4
Functions
In this lesson you’ll learn about functions — the construct which gives developers the ability to organize and reuse code. Understanding functions is a crucial step to becoming an iOS developer and once you finish this lesson you'll be able to create and use them in Swift.
Prerequisites and Requirements
This course assumes no prior programming experience. Basic computer literacy and an understanding of how to navigate the macOS is recommended.
