Asynchronous Operations in Swift explained in a Swift Playground

Asynchronous Operations in Swift - Playground

This project contains a playground to demonstrate Asynchronous Operations in Swift. It's been used in my presentation that I've performed at Swift Paris and CocoaHeadsNL. Slides from this presentation can be found here and a live recording can be found here.

Swift Playground

The playground can be used to go over each element of operations. It's great to play around and see what each functionality does.

It also demonstrate 3 different types of Asynchronous Operations:

• The base AsyncOperation: Everything that is needed to create a asynchronous operation
• An AsyncResultOperation: An enhanced version of the AsyncOperation that adds a Result<Success, Failure> type
• The ChainedAsyncResultOperation: All of the above but then chainable

Example Project

The example project references the operation classes and allows you to play around with the code by building an app.

Interesting resources

All of this content has been published in my chapter for the Swift for Good book. Definitely consider buying the book as all revenue is going to charity. The book is written by 20 different authors from the community and contains high quality Swift content.

You can also find blog posts about Operations on my blog SwiftLee:
