Swift Fundamentals: Mastering the Basics with Swift & iOS

Explore variables and constants in Swift by creating and mutating strings, numbers, and booleans in Xcode, and learn when to use let versus var.

Explore how Swift operators affect values, including assignment, binary, modulo, and compound operators, with string concatenation and real-world examples. See how comparison operators drive boolean decisions in code and apps.

Learn string interpolation in Swift by injecting values into strings, and see how dynamic data updates using variables like age and greeting, with practical examples in Xcode playgrounds.

Explore conditional programming with if, else, and else if, using boolean variables and logical operators to model real-life decisions like age and affordability.

Explore dictionaries, a data structure of unique key-value pairs used for fast lookups, with examples like social security numbers and stock tickers, and learn creation, lookup, and update.

Master while loops by understanding conditional execution, booleans, and comparison operators, and compare them with for loops through a countdown example in Swift.

Explore for loops and while loops in Swift. Learn to define ranges, iterate over arrays with indices, and apply operations such as discounts to prices within a data set.

Explore Swift fundamentals by learning what functions are, how to define and call them, pass parameters, return values, and reuse logic with real life examples.

Master arrays as ordered lists that store values of the same type, illustrated by shopping carts, expenses lists, and to-do lists, and learn operations like append, remove at, and insert.

Explore Swift optionals and safe handling of nil values through real-life examples, unwrapping with if let and guard, and using default values to avoid crashes.

Learn how structs define templates with properties and functions to model real world objects like users, posts, and vehicles in Swift, create instances and arrays of them, and add methods.

Develop Swift skills by printing odd and even values with loops and the modulo operator, and learn to use lower and upper bounds to control dynamic ranges.

Learn to compute the sum, max, and min of an integer array in Swift using a for loop, building a running total and updating bounds.

Build a guest list app in Swift using guest and guest list structures, enabling name search, age filtering, RSVP updates, and a report of attendees and those over 21.

Learn to build a Swift shopping cart by modeling a product and a cart, adding and removing items, applying dollar and percentage discounts, computing totals, and printing receipts.
