## What it is
A Swift library providing fluent, chainable syntactic sugar over Grand Central Dispatch (GCD) asynchronous dispatches. It supports chaining blocks across quality-of-service queues (main, user-initiated, background, etc.) without nested indentation, plus AsyncGroup for running parallel blocks and waiting on completion.

## Use cases
- chain async blocks in swift without deep nesting
- simpler syntax for grand central dispatch
- run work on a background queue then update the ui on the main queue
- run several background tasks in parallel and wait for all to finish
- dispatch to custom queues with readable chained code
- swift wrapper around dispatchqueue async calls

## When to choose
- you maintain an older Swift codebase (iOS 8+/Swift 5.1 era) that predates structured concurrency and want readable GCD chaining
- you prefer fluent chaining over nested DispatchQueue.global().async blocks
- you need simple fire-and-forget dispatch to QoS queues or a group of parallel blocks with a wait

## When to avoid
- you are starting a new project - Swift's built-in async/await, Task, and task groups supersede this library
- you need an actively maintained dependency - the project is explicitly no longer maintained
- you need advanced concurrency features like cancellation, structured error handling, or actors
