Description
What you’ll learn
-
Understand the fundamentals of concurrency and asynchronous programming in Swift.
-
Compare and contrast DispatchQueue and async/await for managing asynchronous tasks.
-
Safely handle shared mutable state using actors to prevent race conditions.
-
Refactor legacy code using structured concurrency for better readability and safety.
-
Apply @MainActor and task isolation to safely manage UI updates in SwiftUI.
-
Identify and resolve callback hell by converting closures into async/await patterns.
-
Trace thread context and execution flow between background and main threads.
-
Build concurrency-safe services and view models using both GCD and structured concurrency.
Are you a Swift developer still reaching for DispatchQueue every time you need to go async? Do terms like @MainActor, Task, and actor feel abstract or disconnected from the kind of code you actually write every day?
This course is your bridge.
“Goodbye GCD” is a clear, practical, and no-fluff introduction to modern Swift concurrency — built specifically for developers like you who know how to use DispatchQueue but want to understand and fully adopt async/await.
We don’t assume you’re starting from scratch, nor do we bury you in theory. Instead, this course meets you where you are: inside real-world mobile code. We use DispatchQueue as a familiar reference point to explain how structured concurrency works, why it exists, and how you can use it to write cleaner, safer, and more maintainable Swift.
You’ll see exactly how async/await improves upon traditional approaches, how to think in terms of thread context and task suspension, and how features like @MainActor and actor solve problems you’ve likely encountered but had to hack around.
By the end of the course, you won’t just know how to use Swift concurrency — you’ll understand how it thinks.
Whether you’re transitioning from UIKit to SwiftUI, refactoring legacy code, or preparing for your next big iOS role, this course will equip you with the concurrency foundation modern apps demand — without wasting your time.
If you’re ready to move beyond callback hell and take control of concurrency in Swift the right way, this course is for you.
Who this course is for:
- UIKit developers transitioning to SwiftUI and structured concurrency
- iOS engineers looking to modernize legacy GCD-based code
- Developers who struggle with managing async tasks and thread safety
- Swift developers curious about the actor model and structured concurrency
- Intermediate Swift learners ready to go beyond basics
- Mobile developers seeking better ways to handle background work
- Programmers looking to write cleaner, more maintainable async code
- SwiftUI users who want to safely update UI in concurrent environments
- Engineers preparing for iOS interviews with concurrency topics
- Teams modernizing their app architecture to use Swift’s async/await model
