Questions tagged [promisekit]

PromiseKit is Objective-C and Swift Promises implementation. It is also a collection of helper functions that make the typical asynchronous patterns we use in iOS development delightful too.

Modern development is highly asynchronous: isn’t it about time iOS developers had tools that made programming asynchronously powerful, easy and delightful?

PromisesKit is not just a Promises implementation, it is also a collection of helper functions that make the typical asynchronous patterns we use in iOS development delightful too.

In addition, PromisesKit is designed to be integrated into other CocoaPods. If your library has asynchronous operations then consider adding an opt-in subspec that provides Promises for your users. Documentation to help you integrate PromiseKit into your own pods is provided later in this guide.

PromisesKit is available in Objective-C and Swift flavors.
