Your First Programming LanguageStart Free Course
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.
This free course is your first step towards a new career with the Become an iOS Developer Nanodegree Program.
Enhance your skill set and boost your hirability through innovative, independent learning.
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.
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.
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.
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.
This course assumes no prior programming experience. Basic computer literacy and an understanding of how to navigate the macOS is recommended.
