Learn about Dictionaries, Arrays, and Sets and perform basic operations including: append, count, insert, remove, update, find, and retrieve.
Practice fast iteration with for-in loops by iterating through items in Arrays and Dictionaries, also learn how Swift handles if-else and switch statements.
Define and call functions, correctly using local and external parameters; identify parameter types and return types.
Practice building custom classes with their own properties and methods.
Learn the difference between value types and references types and practice choosing when to use enums, structs, and classes.
Learn how protocols and extensions help keep your code DRY. Given code snippets, fix compiler errors by conforming to and implementing appropriate protocols.
Practice using Swift closures with the functions, sorted() and filter(). You'll also learn shorthand to make your closure expressions super concise.
