About iOS Developer
iOS development is the craft of building apps for the iPhone and iPad, using Apple's
tools and the Swift language. This course follows the path most developers take to get
there. It starts with Introduction to iOS Development (how the platform
works, the app lifecycle, and what you can build) and Xcode & Setup
(the IDE, simulators, running on a real device, and your first app).
Next come the language foundations: Swift Basics (constants, variables,
and types), Collections & Control Flow (arrays, dictionaries, sets,
and loops), and Functions, Closures & Optionals, the feature that
makes Swift safe. Structs, Classes & Protocols then covers how Swift
models data, including value vs reference types, protocols, and generics.
With Swift in hand, SwiftUI Fundamentals introduces declarative
interfaces with views, modifiers, and layout, while State, Navigation &
Architecture covers data flow, multi-screen apps, and patterns like MVVM.
UIKit Essentials covers the framework behind countless existing apps,
including view controllers, Auto Layout, and mixing it with SwiftUI.
Finally, Networking & Concurrency covers calling APIs with
URLSession and async/await, Persistence & Device Features covers
saving data and using the camera, location, and notifications, and
Testing, Debugging & App Store covers XCTest, Instruments, and
shipping your app to users through TestFlight and the App Store.

What You Can Do After This Course
By the end of the curriculum you'll have worked through 5 hands-on projects and
covered the core of what a developer role expects from someone who "knows iOS."
Concretely, you'll be able to:
Write clean, idiomatic Swift — comfortable with optionals, closures, and the language's conventions.
Model data with the right tools — choose between structs, classes, and protocols with confidence.
Build modern interfaces — create responsive, multi-screen apps with SwiftUI and navigation.
Structure apps for growth — manage state and separate concerns with MVVM.
Work with existing codebases — read and extend UIKit code and mix it with SwiftUI.
Connect to the real world — call APIs, save data locally, and use device features like the camera and notifications.
Test, debug, and ship — write tests, profile with Instruments, and publish through TestFlight and the App Store.
