...A thunk is a function that wraps an expression in order to delay its evaluation. Redux Thunk middleware allows you to write action creators that, rather than return an action will return a function instead. If you want to delay the dispatch of an action, or to dispatch only after meeting a certain condition, then the thunk can be used. Thunks are ideal middleware for a number of cases, in particular for basic Redux side effects logic, complex synchronous logic that must access the store, and simple async logic like AJAX requests.

...Instead of simple how-to recipes, the project collects detailed explanations, system internals analyses, and real-world insights into core subsystems like memory management (ARC), threading and Grand Central Dispatch, Objective-C/Swift runtime behavior, UIKit rendering pipelines, and effective use of concurrency. It also covers architectural and performance topics such as dynamic layout optimization, view lifecycle subtleties, Swift language pitfalls, and integration with low-level APIs such as Metal or CoreAnimation. By aggregating authoritative references, experiments, and code snippets, the guide helps developers reason through tradeoffs, debug subtle issues, and architect large-scale iOS systems.
