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• you need an actively maintained dependency - the project is explicitly no longer maintained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
