Udemy – SwiftUI Property Wrappers Explained Through a Real Feed App

Most tutorials and courses explain SwiftUI property wrappers in isolation—@State, @Published, @ObservedObject—but never show you how they actually work together in a real app. That’s where this course comes in.

This course is designed for iOS developers who are confused by property wrappers and overwhelmed by vague explanations. We focus on understanding why each property wrapper exists and how it’s intended to be used inside classes, structs, and most importantly, within the MVVM design pattern. You’ll build a fully functional RSS feed app from scratch, learning how to structure your code with a clean separation of concerns and how to inject dependencies into your view models properly.

Along the way, you’ll implement:

• @State, @Published, @ObservedObject, and @StateObject in context
• A networking layer using async/await and retry logic
• Feed parsing with FeedKit
• A SwiftUI UI driven by real-time view model updates
• Dependency injection for testability and clarity
• Proper use of @MainActor to handle UI updates safely

This course is practical, focused, and built for self-taught developers and beginners who want to move beyond copy-paste coding and really understand how SwiftUI apps are built. If you’ve been struggling to make sense of property wrappers, this course will give you the clarity and confidence to use them correctly—and build better apps because of it.
