Discover how to declare and use variables and constants in Swift, using var and let, to store, update, and protect information like age and name.

Explore Swift types by comparing strings as text and ints as whole numbers, and learn to declare variables and constants with type annotations using a colon.

Learn how Swift handles math with doubles and floats, and how to mix types using conversions for accurate results. Tackle a feet-and-inches challenge and apply the order of operations.

Master swift optionals by treating values as either a real value or nil. Create optional types and unwrap safely with if let.

Learn how classes in Swift act as blueprints to create independent objects with their own properties and methods, and how to instantiate, access, and modify them.

Learn how to use enums in Swift 5, with a compass example and dot syntax, and apply a fur color enum to enforce valid dog colors for cleaner code.

Learn how to replace complex if statements with switches to handle ranges, enums, and exhaustive cases, and apply them to directions and color examples.

Build a Swift 5 function that takes any text, lowercases it, removes punctuation, counts words, and ranks them from most to least frequent for clear text analysis.

Explore Swift five api stability, its impact on runtime and reduced app sizes, and how code compiles back to a single api for quicker load times.

Learn to work with strings and ints, using double quotes for text. Explore variables and constants, camelcase naming, and examples like lucky number eight and pizza.

Create a label in the storyboard, set its text, and center it with constraints across devices, then run in the iOS simulator to preview changes.
