Swift
Apps for iPhone and iPad.
Swift is the language of Apple's platforms: iPhone, iPad, Mac, Apple Watch and Vision Pro. It is fast, safe by design and pleasant to read. This track starts from zero: constants and variables, optionals, decisions and loops, functions and closures, then structs, classes, enums and protocols. You will meet Swift 6's compile-time protection against data races, take a first look at async code and actors, and build your first SwiftUI screen. A last module turns it into a real app: lists and navigation, JSON from the network with Codable, and saving data with SwiftData.
Every lesson is short, practical and checked with quizzes, so you learn by doing.
