Summary

In this chapter, we explored Swift on the server. We developed a web application that runs entirely in Swift. Our application also communicates with Slack to post messages. We used the Vapor web framework to create a Swift web server, and you learned how to call Slack webhooks from Swift. While our example was fairly simple, it is easy to see how we could expand it to a larger and more complex application leveraging the power of Swift.

This brings us to the end of the book. We've covered a lot of material and learned the new features of Swift 3. We discussed Apple's motivation and objectives for the evolution of Swift. I have shown you where to find documentation on the language and how to get involved with the future direction of Swift. We explored Swift on Linux and some of the possibilities this creates for server-side Swift applications. Swift 3 adds new language features that improve many of the libraries that you will use everyday in your coding projects.
