Learn Swift Programming Syntax

This course assumes prior programming experience! Specifically, you should be familiar with programming concepts like variables, if statements, and loops, as well as object-oriented concepts like methods and classesYou will also need access to a Mac compu

Classes, Properties, and MethodsPractice building custom classes with their own properties and methodsLearn about type properties and computed propertiesSee example use cases for type methods and instance methods

Closure ExpressionsPractice using Swift closures with the functions, sorted() and filter()Learn shorthand closure expression syntax to make your closures super conciseSee how closures are used in animations in the method, animateWithDuration

Control Flow: Loops, If statements, and SwitchesPractice fast iteration with for-in loops by iterating through items in Arrays and DictionariesCreate programming logic of increasing complexity with if-else statementsDelight in the convenience and concise

Enums and StructsLearn the difference between value types and references typesPractice choosing when to use enums, structs, and classesUse enums to make your switch statements extra Swifty

How to Write and Call Functions in SwiftDefine and call functionsCorrectly use local and external parametersIdentify parameter types and return types

Optional TypesDeclare explicitly and implicitly unwrapped optionalsUnwrap optionals using both optional binding and optional chainingPractice safely unwrapping optionals and learn to avoid errors

Protocols and ExtensionsLearn how protocols and extensions can help keep your code DRYGiven a series of code snippets, fix compiler errors by implementing protocolsEdit the code in a sample app to see extensions in action

Swift CollectionsLearn about the Swift Collection Types: Dictionaries, Arrays, and SetsPerform basic operations including: append, count, insert, remove, update, find, and retrievePractice manipulating collections with exercises in Swift playgrounds
