The Ultimate iOS 14, Swift 5 and WatchOS 7 Masterclass

Explore Swift conditional testing, ternary, and nil coalescing operators, including comparisons, boolean logic, and string value checks, to drive control flow and concise code.

Discover Swift collection types, starting with arrays, and learn how to declare, initialize, and reassign them, compare arrays, sets, and dictionaries, and understand tuples versus collections through practical examples.

Learn common array operations in Swift, including retrieving counts, first and last elements, and index access, plus modifying arrays with append, insert, replace, and remove on a tuple-based inventory.

Explore the fundamentals of control flow, including if and else, nested conditions, switch statements, null value checks, and loops, while learning when to use each construct.

Explore control flow with if and else statements that run code blocks based on true or false tests. See a simple left-right player position example.

Explore how else if statements extend basic if logic to test multiple conditions, using button presses like left, right, up, and down, plus a default else to handle invalid input.

Explore switch statements in Swift, compare them to if else, learn the syntax and default clause, and see how button presses update x and y positions.

Explore advanced switch statement techniques in swift, including range tests, multiple values, and tuple matching with decomposing bindings and where clauses.

Learn how function return types and return statements work, return values as expressions, and how blank returns exit functions or loops with practical max and game examples.

Learn how to define an item category as an enumeration, restrict values with cases, use raw values or associated values, and implement exhaustive switch statements.

Learn to connect outlets and actions in a view controller by linking UI elements to code, then update a label's text on button press.

Learn to build a view from a data collection using a for each loop to display a 14-day forecast in swiftui, with text styling and padding.

Learn how to layer an image with text using a z stack to place today's weather over a clouds background image, creating a simple weather app interface.
