Hydra is a lightweight, full-featured Promises library for Swift, inspired by JavaScript's A+ promise spec and ES8 async/await. It lets developers write asynchronous code in a synchronous style with operators like all, any, retry, timeout, map, and zip.

Use cases

  • write async code in Swift without callback nesting
  • chain multiple asynchronous operations with promises
  • retry failed async operations with backoff
  • run several async tasks in parallel and wait for all
  • add timeouts to asynchronous operations
  • cancel in-flight async operations

When to choose

  • you're on Swift 3.x/4.x and need promise-based concurrency
  • you want async/await-style syntax before Swift's native support
  • you need rich promise combinators like all, any, zip, retry

When to avoid

  • you're on modern Swift with built-in async/await and structured concurrency
  • you need an actively maintained library (last release 2021)
  • your project targets only Apple platforms with Combine available
