Important Notice

Since 0.9.7 Hydra implements Cancellable Promises. In order to support this new feature we have slightly modified the Body signature of the Promise; in order to make your source code compatible you just need to add the third parameter along with resolve,reject: operation.
operation encapsulate the logic to support Invalidation Token. It's just and object of type PromiseStatus you can query to see if a Promise is marked to be cancelled from the outside.
If you are not interested in using it in your Promise declaration just mark it as _.

To sum up your code:

return Promise<Int>(in: .main, token: token, { resolve, reject in ...

needs to be:

return Promise<Int>(in: .main, token: token, { resolve, reject, operation in // or resolve, reject, _

New Features:

• #25 Added support for Cancellable Promises via InvalidationToken. See the documentation for more info.

This is the latest update for Swift 3.x.

Changes include:

• #31 : Introduced nested generics
• Minor fixes to documentation

• #22 Fixed an issue with any operator which in several occasions does not work.
• #24 Fixed never chainable if return rejected promise in recover operator closure.
• #26 Added concurrency argument in all operator; it allows you to set the number of max concurrent promises running for an all task in order to reduce memory and cpu footprint.
• #28 Fixed Promise's memory leak
• #29 Cleaned up the process of running the observer
• #18, #20 Refactoring of several func inside the Promise's class.
