The Ultimate 70+ Hours iOS Development Bootcamp

download and install xcode from apple, launch it on a mac, and create a swift playground to start learning the swift language before building actual ios applications.

Master Swift basics by declaring variables with var and constants with let, and explore type inference and common types like string, integer, double, and boolean in Xcode playgrounds.

Learn Swift operators and expressions, including arithmetic, comparison, and logical operators; explore compound assignment operators and the ternary operator with practical variable examples.

Explore strings and string interpolation in Swift, learn concatenation with the plus operator, and see how immutability and append affect performance, readability, and automatic type conversion.

Explore conditional statements in programming, using if, else, and else if to evaluate temperatures and decide outcomes, and learn about the ternary operator and switch statements.

Learn how switch statements in Swift enable exhaustive, pattern-matching decisions across ranges and discrete cases, with examples for days of week and graded scores.

Explore how to use loops to repeat tasks efficiently. From for-in over arrays of fruits to while and repeat-while counters, learn continue and break to control flow.

Explore Swift functions, covering syntax, parameters, return values, and how functions act as first-class citizens, callable and returnable, with argument labels and defaults.

Explore closures as self-contained blocks in Swift, learn how they capture surrounding variables, and build add, multiply, and incrementer closures with trailing closure syntax.

Learn how the nil coalescing operator unwraps optionals in Swift, using ?? to provide a default value when a name is nil and to print results.

Explore optional chaining in Swift to safely access properties and methods of optional types. Apply if let unwrapping and nil coalescing for nested objects.

Explore why forced unwrapping in Swift is risky, how optionals and nil values influence unwrapping, and why it should be a last resort, with examples on URLs and SwiftUI previews.

Learn how implicitly unwrapped optionals work in Swift and how to safely connect IBOutlets in UIKit, avoiding runtime nil errors when labels are not connected.

Explore optional mapping and flat mapping in Swift, showing how map accesses the unwrapped version and transforms optional values, while flatMap flattens optional results, with practical examples and comparisons.

Explore associated types in Swift by detailing a web service protocol with a generic codable model. Define concrete models like movie or user via type aliases.

Explore generic functions in Swift to create a single, reusable first element utility that works across strings, numbers, and other types using a type parameter.

Explore how generics apply to structs and classes, using a generic pair with first and second types t and k, and a generic stack with push and pop.

Explore how to apply constraints to generic types, ensuring only Encodable data passes into a JSON encoder by requiring generics to conform to Encodable.

Learn protocol inheritance in Swift by defining animal and can fly protocols, then implement a bird that conforms to both, addressing missing implementations and when inheritance makes sense.

Discover protocol composition in swift, where codable equals the combination of decodable and encodable. See how a duck can conform to both and be encoded or decoded.

Learn how protocols act as types in Swift by defining an animal protocol with a makeSound method, implementing dog and cat conformers, and calling makeSound on a generic animal.

Explore protocol extensions in swift, which provide a default implementation for protocol methods, allow overriding, and let conforming types share a common behavior like make sound.

Explore how Swift enums use raw values to auto-increment integers (Sunday as 1, Monday as 2) and to encode and decode with Codable for HTTP status codes and user roles.

Learn how associated values extend enums in Swift with practical examples, including HTTP requests with URLs and parameters and using result types for success and failure data.

Understand how nested enums work in Swift by placing a menu enum inside a restaurant enum, with entrees and desserts as menu items. Apply this hierarchy to routes in SwiftUI.

Explore how enums in swift conform to protocols, using fruit examples to compare equality with equatable and discuss other protocols such as hashable.

Explore how to define a Swift enum with static functions and properties, returning all HTTP methods and providing descriptive titles for display.

Explore enums with computed properties in Swift by modeling weather with temperature and rainfall, and deriving a nice weather boolean using a switch on self.

Launch a new SwiftUI project in Xcode, select the app template, and build a content view that conforms to the view protocol using a struct and live text previews.

Learn to customize text and combine views with stacks in SwiftUI. Build vertical and horizontal stacks, adjust spacing, and apply foreground color, fonts, and parent styles.

Display images in SwiftUI by importing assets, resizing with resizable and aspect ratio, shaping with clip and padding, and loading from URLs with async image, placeholders, and progress indicators.

Model hikes with name, photo, and miles, display them in a SwiftUI list with images and formatted miles, and conform to Identifiable with a UUID for navigation in next lecture.

Wrap the hiking list in a navigation stack, create a reusable hike cell view, pass hike data, and use a navigation link to navigate to a hike detail screen.

Implement a SwiftUI hike detail screen that displays the hike image, name, and miles, accepts a hike dependency, and uses a preview with an inline navigation title.

Add tap and zooming animation to an image in a hiking app by toggling a zoomed state and switching content mode and aspect ratio between fit and fill with animation.
