Your Brain 🧠 on Swift Concurrency
summary
Asserts that await is not blocking and demonstrates why awaiting frees threads by suspending tasks, not threads, with diagrams of tasks moving between threads. Explains actor isolation, actor reentrancy, implicit MainActor for SwiftUI ObservableObject, and that functions run on the global executor unless instructed otherwise. Distinguishes unstructured, detached and structured tasks, shows async let and task groups for child tasks, warns to create tasks sparingly and prefer unstructured over detached.
