Swift Task Lifecycle Management - Structured vs Unstructured Concurrency
Swift Concurrency fundamentally changed how asynchronous programming works in Swift. Before async/await arrived, developers relied heavily on completion handlers, delegates, Combine pipelines, and Grand Central Dispatch (GCD). These approaches worked, but they often made asynchronous code difficult to reason about, debug, and maintain. With Swift Concurrency, Apple introduced a model centered around tasks, structured concurrency, and actor isolation. One of the most important concepts to understand in this model is the difference between structured and unstructured concurrency. ...
