Free online courseiOS application development

Course Description

Want to turn app ideas into polished iPhone and iPad experiences? This free online course guides you through modern iOS application development using SwiftUI, Apple’s declarative UI framework, so you can design interfaces faster, iterate confidently, and ship features with a clear architecture.

You’ll begin with the essentials of SwiftUI and quickly move beyond basics into the patterns that make apps maintainable. You’ll practice building views the SwiftUI way, understanding why the UI is described as a function of state and why views are treated as read-only snapshots. From there, you’ll develop a strong foundation in MVVM, learning how to separate UI from business logic so your code remains testable, scalable, and easier to change as your app grows.

As you progress, you’ll connect layout and composition with reusable components, explore shapes and protocols, and learn how Swift’s type system supports safer app development. You’ll also dive into view modifiers, gestures, and animation, gaining the ability to add smooth interactions that make an app feel responsive and professional.

Practical building is a core focus. You’ll work through app-style projects that reinforce state management, user interaction, drag and drop, and document-style workflows. Along the way, you’ll encounter multithreading concepts for keeping the interface fluid, plus robust error handling and persistence strategies so data can live beyond a single session.

By the end, you’ll understand how to navigate common SwiftUI app structures, work with bindings and navigation, integrate with UIKit when necessary, and think through multi-platform considerations when targeting iOS and macOS. If you’re aiming for a portfolio project, a first mobile developer role, or a modern upgrade from UIKit-only workflows, this course gives you a solid, hands-on path to building with SwiftUI.
