Apple's The Swift Programming Language
You can download Supplemental Materials, Lesson Videos and Transcripts from Downloadables (bottom right corner of the Classroom) or from the Dashboard (first option on the navigation bar on the left hand side).
In this lesson, you'll become familiar with Swift types and operators, and develop deftness in defining variables and constants.
In this lesson, you'll declare explicitly and implicitly unwrapped optionals, and unwrap optionals using both optional binding and optional chaining.
In this lesson, you'll learn about Dictionaries, Arrays, and Sets and perform basic operations including: append, count, insert, remove, update, find, and retrieve.
In this lesson, you'll practice fast iteration with for-in loops by iterating through items in Arrays and Dictionaries. You'll also get experience with if-else statements and switch statements.
In this lesson, you'll define and call functions, correctly use local and external parameters, and identify parameter types and return types.
In this lesson, you'll practice building custom classes with their own properties and methods.
In this lesson, you'll learn the difference between value types and references types and practice choosing when to use enums, structs, and classes.
In this lesson, you'll learn how protocols and extensions can help keep your code DRY. Given a series of code snippets, you'll fix compiler errors by conforming to and implementing the appropriate protocols.
In this lesson, you'll practice using Swift closures with the functions, sorted() and filter(). You'll also learn shorthand to make your closure expressions super concise.
