Promises are a well-known design pattern used to delay evaluation of future values, and to pipeline operations in an asynchronous manner. Typically, there are three internal states: Pending, Fulfilled, Rejected, used to control Promises’ behavior, but this lacks core interfaces such as Cancel, Pause, Resume, Progress, that are all essential in our daily iOS & OS X development. Needing more powerful classes than Promise or NSOperation, SwiftTask was created, and entirely written in Swift.

By taking a closer look into SwiftTask's resume/progress handling, we will explore a new approach to the Reactive Programming paradigm. Every Task will eventually become a Stream.

Overview:

1. What are Promises?

• History of event-driven programming

• Callback hells and Promise

2. Extending Promises

• Introduction of SwiftTask

• Demo

3. Going Reactive

• Introduction to ReactKit

• Demo

4. V.S. & Acknowledgements

• PromiseKit / Bolts-iOS

• FBKVOController

• ReactiveCocoa

5. Conclusion
