Swift

This is your ultimate resource for Swift, the programming language for Apple devices! Get to know Swift’s syntax and learn to work with elements such as variables and collections. Use Swift’s built-in features for debugging, error handling, and memory management to streamline your development process. Then move to more advanced topics like concurrency and custom modules. Follow along with downloadable code examples to get practical experience working with the language. Become a Swift master in no time!

Your comprehensive guide to the Swift programming language
Work with variables, collections, enums, structs, and other language elements
Practice as you learn with downloadable code snippets

You'll learn about:

Swift Syntax:
Understand the elements of the Swift programming language. Learn to use variables, data types, and operators, and then string them together into collections. Implement control flow statements to execute your code based on predefined conditions.
Features and Programming Techniques:
Work with object-oriented programming techniques in Swift using enums and structs. Improve your code using Swift’s variety of features, including Automatic Reference Counting for memory management, built-in debugging, and nil value management with optionals.
Coding with Swift:
Start developing with Swift right away! Download code samples and follow line-by-line instructions for everything from your first “Hello, world!” to custom reusable modules.

Key Highlights:

Variables and collections
Control flow
Functions
