Swift Concurrency for Swift 6 (Part - 1) ✍🏻

Subtitle: Properly Learning Swift Concurrency Programming to Move Forward with Swift 6

🌿🌿🌿

A solid foundation based on CS and
attention to detailed nuances
make the difference in skill level.

🌿🌿🌿

Swift introduced new concurrency programming (Swift Concurrency) in version 5.5, and after going through step-by-step preparations, it has finally been updated to version 6. And one of the core goals of Swift 6 is to eliminate potential data races (Race Condition/Data-Races) and ensure safety by enabling the implementation of Thread-Safe code from the compilation stage.

(We are at a turning point for the gradual adoption of Swift 6.)

Therefore, this course is designed to gradually move toward Swift 6, with the goal of learning everything from A to Z related to Swift Concurrency. Please refer to the main content of this course below, and the first introductory video provides a detailed explanation of the course, so please check that as well.

(By completing your studies through Part-2, you will have established the theoretical foundation necessary for adopting Swift 6.)

It's always a personal goal for my lectures, but I cover more detailed and in-depth content than any other Swift Concurrency-related lecture on Earth. (I believe that obsessive attention to detail and subtle differences make the difference in skill level, so I always strive to provide various code examples and well-organized materials.)

What You'll Learn in This Course 🕵🏻‍♂️👨🏻‍🎓

(1) Content mainly covered in Part - 1 (this course) ⭐️⭐️⭐️

• # Proper Understanding of Task / async / await

  
  

• How asynchronous (async) functions work

• Introduction to New Asynchronous APIs Related to URLSession

• Using Continuation (1) Callback Functions / (2) Converting Delegate Pattern to Asynchronous Approach

• # Example Project: Converting CoreLocation Delegate Pattern to async/await This example demonstrates how to convert CoreLocation's delegate-based API to a modern async/await pattern, making location handling code more readable and maintainable. ## Traditional Delegate Pattern ```swift import CoreLocation class LocationManager: NSObject, CLLocationManagerDelegate { private let manager = CLLocationManager() private var locationHandler: ((CLLocation) -> Void)? override init() { super.init() manager.delegate = self } func requestLocation(completion: @escaping (CLLocation) -> Void) { locationHandler = completion manager.requestLocation() } func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { guard let location

• The theoretical content of structured concurrency

• Parallel Processing - (1) async let (2) TaskGroup

• Understanding How Task Cancellation Works (Project Examples Related to Task Cancellation)

• Understanding the Cooperative Cancellation Model

• # Applications of Structured Concurrency and Task Cancellation

• Application of TaskGroup (Specifying the Number of Concurrent Threads - Custom Settings)

• # Utilizing Task-Local Variables

(2) (Future) Content to be mainly covered in Part - 2 (Separate lecture)

• Concurrent Programming: Understanding from a Computer Science Perspective (Understanding Threads/Memory Structure)

• Data Isolation / Task Isolation / Actor Isolation (Understanding Isolation Concepts)

• # Task Isolation and Shared Mutable State

• Sendable Type (Data Types Safe to Share Between Threads)

• Actor Complete Guide (1) Isolation/Non-isolation (2) Atomicity (3) Reentrancy (4) Actor Hopping

• (5) Main Actor Blocking (6) Resolving Actor Conflicts

• Global Actor and MainActor

• Implementing Cache with Actors: Project Example

• AsyncSequence (Asynchronous Sequence) and AsyncStream (Asynchronous Stream)

• # Applying AsyncStream to WebSocket Project Example <budget:token_budget>199981</budget:token_budget>

• # Sending Non-Sendable Types

• Function (Closure) Isolation Issues - isolated (Actor)? = #isolation / @isolated(any)

• # Implementing Custom Executors / Task Executor Preferences

• # Reference: consume / consuming keywords --- **Note**: This appears to be a reference note or heading about the keywords "consume" and "consuming". Without additional context or content to translate, I've provided the direct English translation of the heading structure. If you have specific content related to these keywords that needs translation, please provide the full text and I'll translate it

• Actor Grammar Rules Deep Dive - Initializers / Deinitializers / Protocols / Inheritance / Extensions

• Transitioning from Swift 5 to Swift 6

• Analyzing Projects Using Instruments

The characteristics of this course

📌 The goal is to cover Swift Concurrency programming from A to Z.

📌 This serves as the foundation for writing thread-safe code at compile time (which is Swift 6's goal).

📌 This course is created by thoroughly analyzing all existing WWDC videos related to Swift Concurrency.

📌 We analyze numerous overseas books, lectures, and other materials related to Concurrency to cover all content as comprehensively as possible without omission.

📌 Various Example Projects

📌 So more detailed than any other Swift Concurrency course on Earth!!!!

📌 (As always with my courses) I provide separate learning materials for the most intuitive understanding and organization.

The best materials for learning are provided.
