## Async Workflow

All apps have asynchronous workflows. Apple's `NSOperation` and `NSOperationQueue` provide a foundation for building arbitrarily complex workflows. This demo code coincides with my [STL CocoaHeads](https://www.meetup.com/St-Louis-CocoaHeads/events/253392866/) talk on techniques for building "async workflows". 

The demo code shows how to:

- use dependent operations

- pass data between operations using a thread-safe key/value store (i.e `Session`)

- track progress using `NSProgress`

- support an easy to understand cancellation policy

- allow app background execution (with just a few lines of code)

## Presentation Slides

Be sure to review the CocoaHeads [presentation slides](AsyncWorkflow.pdf) for additional notes and details.
