PromiseKit is a Swift and Objective-C library implementing promises to simplify asynchronous programming. It supports iOS, macOS, tvOS, watchOS, Linux, and Android with CocoaPods, Carthage, and SwiftPM integration.

Use cases

  • handle async network requests in Swift
  • avoid callback hell in iOS apps
  • combine multiple async tasks with when()
  • chain asynchronous operations with error handling
  • write readable async code in Objective-C

When to choose

  • you're on Swift 5.4 or earlier without async/await
  • you need Objective-C bridging for promises
  • you maintain legacy iOS/macOS codebases using CocoaPods

When to avoid

  • you're using Swift 5.5+ where async/await is built in
  • you're starting a new project with modern Swift concurrency
  • you need a cross-language async runtime outside Apple platforms
