Compare floats and doubles, noting that floats handle up to seven decimal places and doubles up to fourteen, with bank balance examples and type conversion for math functions.

Explain the difference between characters and strings in Swift 3, covering length, quoting, concatenation with plus and plus equals, and string to integer conversions with examples.

Explore Swift optional variables, learn how a question mark makes a type optional and allows nil, and compare with regular variables and constants across integers, booleans, and strings.

Master Swift if statements to control code flow by testing conditions. Learn how booleans, true/false tests, and double equals drive decisions in examples using constants, variables, and score tracking.

Learn to test multiple conditions in one if statement using the and and or operators, then explore nested if statements for sequential checks, illustrated with username and password login logic.

Explore how if, else if, and else statements evaluate conditions in sequence, with else handling all other outcomes. Use bank balance and purchase examples to illustrate their differences.

learn how if let binds optional values in Swift 3, using optional variables, nil handling, and optional binding to safely execute code when values exist.

Master boolean and number arrays in Swift 3, with hands-on examples of integers, floats, doubles, and booleans. Learn how to initialize, manipulate, and resize arrays in playgrounds.

Explore integer, float, and double arrays, compare precision and usage, and learn character and string arrays for storing and passing data in real‑world applications.

Learn how to access and modify elements in arrays, using integer and string arrays, with zero-based indexing and examples that show updating specific elements.

Discover how to initialize an array with repeated values using a repeating approach, and how to add elements to an existing array with append or plus equals.

Master array manipulation in Swift 3 by inserting and removing elements at specific indices. Learn to access, modify, and explore array functions using playgrounds and the dot syntax.

Master Swift for-in loops to execute code multiple times, using index ranges and inclusive versus exclusive bounds, and compare with traditional for loops for clarity.

Learn how to use the loop index inside for loops to perform operations, print results, and track counts, including starting values and using the index to multiply values.

Combine arrays with for-in loops to iterate and print each element efficiently. Learn zero-based indexing, using count, and optionally modify elements or concatenate them into strings.

Construct arrays from an empty array with a for loop and the append function, building a 0 through 10 integer sequence and uniform string arrays.

Combine for loops and if statements to filter and print specific array elements using conditions, the modulus operator, and index-based tests.

Explore for loops in Swift 3, from basic start and end indices to iterating arrays, applying conditionals, and printing or updating values.

Explore Swift 3 functions, define and call functions with or without parameters and return types, including simple no-parameter no-return examples that print messages.

Explore functions with parameters by printing input strings, doubling integers, and multiplying two numbers, and preview how return types will be used in later functions.

Learn how functions with return types work in Swift by combining strings, returning a string, and storing results in variables or printing them.

Demonstrate functions with multiple return values and types by returning a doubled number and its string form, then show naming and ordering of return values.

explore implementing if statements inside a function to return the maximum of two numbers using a max function, conditionals, and return statements to demonstrate function design.

Learn how to use functions with for loops to iterate over a string array, combine elements into a single string, and return or print the result.

Define and use functions with names, parameters, and optional return types. Build small helper functions, use conditionals and loops, and have functions call other functions to perform tasks.

Explore switch statements and while loops in Swift 3 using playgrounds to test code, understand control flow, and compare with if and for loops.

This lecture demonstrates switch statements by testing a variable’s value against cases like money, map, and cell phone, using a default, and compares them to if statements for cleaner code.

Explore while loops by comparing them to for loops, show how to execute code until a condition is met, and avoid infinite loops.

Explore a Mario-like video game example that uses a while loop to update player and enemy positions, check contact, and end the game when lives run out.

Learn how continue, break, and return statements control loops and functions, skip iterations, exit loops, or exit a function, with practical examples in while, for, and switch structures.

Explore how while loops run code until a condition is met, and for-in loops control iterations. Compare switch statements to if statements, and how break, continue, and return manage flow.

Learn to define new types with enumerations, compare them to classes and structures, and use switches to handle limited value cases in Swift 3.

Explore associated and raw values in enumerations, using shapes and tea examples to show how to attach dimensions or string and integer values, search by raw values, and retrieve cases.

Explore how classes create new instances with properties and behavior, using a bag example to show fields, methods, and how to initialize and modify them.

Understand structures as a middle ground between enumerations and classes, defining properties without functions, and see a bank account example that demonstrates optional owner, id, balance, initialization, and copying.

Explore how structures and classes work together in Swift, nesting a location struct inside a class and modifying its properties via dot notation, including enumerations and raw values.

Learn to add and configure a label in an iOS app with xcode and swift, from project setup and storyboard design to adjusting attributes in the inspector.

Connect the label from the main storyboard to code via an outlet, then initialize and access it in code to modify its text and other properties directly.

Learn to modify a label's text in code rather than the attributes window, by assigning label.text, using a separate function, and running the app to see the change.

Modify label text with label.text and append or remove actions; extract text into a variable, use start and end indices, and adjust text alignment in code or attributes.

Change a label’s text color in code or the attributes inspector and manage scaling by enabling font size to shrink to fit and adjusting the number of lines.

Learn to design a layout with the storyboard, drag-and-drop controls, and code initialization, then configure a label’s text, alignment, and color, recognizing labels display static text.
