Swift is one of the fastest-growing computer languages today. Created by Apple, developers use Swift to make apps for iOS, which runs on more than a billion iPhones around the world. Swift is an open-source language, complete with a compiler, a standard library, and an integrated development environment. It also has a package manager to help you build and distribute your projects.
Swift has a focus on safety, speed, and expressiveness with its use of type inference and automatic memory management. It has many powerful features to make your development easier, including generics, automatic reference counting, closures, and optionals. It uses types to ensure your code doesn’t crash inadvertently bypassing information to a wrong data type, and its syntax encourages you to write clean and understandable code. It’s a language that you’ll find easy to learn and easy to master. You’ll use Swift to build projects and apps for iOS, the desktop, and the web, and have fun while doing it!
Learning Objectives:
- Explain simple and complex data types
- Craft your program’s control flow with conditionals, if statements, and loops
- Understand how to use functions
- Describe the workings of data structures and classes
- Identify when to use methods and how to implement them

Hello, welcome to KnowledgeCity's course on Swift. My name is Mark Nair and I'm an award-winning professor of technology and economics. I've been using and teaching the Swift programming language since Apple first introduced the language at the 2014 Worldwide Developers Conference in San Francisco. Swift is a terrific general purpose modern programming language. Which means it's fast, safe, expressive, and maybe more importantly for us, easy to learn, easy to read, and easy to use. You can use Swift to make apps for iOS devices, the Mac, and even create server side applications. In this course, you'll learn the basics of Swift development from using data and variables to more complex data structures such as arrays and dictionaries. You'll learn how Swift uses functions for reusable code and how structs and classes will help you better organize your logic and code. By the end of this course, you'll be able to write and run your own functional Swift code and you'll understand how variables, constants, and data structures, functions, and methods work within Swift. And you'll be on your way to writing your very own apps. So let's get started.
