What you'll learn

Learning iOS development without understanding Swift can feel like trying to build a house without knowing how to use the tools. In this course, Swift 6 Fundamentals, you’ll learn to read, write, and reason about Swift code with confidence. First, you’ll explore Swift’s type system and how to declare and use variables, constants, and control flow. Next, you’ll discover how to work with optionals, collections, functions, and Swift’s core data structures like tuples, arrays, dictionaries, and sets. Finally, you’ll learn how to define your own types using structs, classes, and enumerations; understand initialization and access control; and get introduced to advanced features like protocols, error handling, closures, generics, and modern concurrency. When you’re finished with this course, you’ll have the skills and knowledge of the Swift programming language needed to write clear, modern code and confidently move forward with iOS or macOS development.
