In this chapter, you looked at the history of Swift and why it stands out from other languages. You then learned why Swift has been leaning toward server development from the beginning. After looking at Swift's performance compared to other languages and frameworks, you learned about Swift on the server and what is currently supported. Docker and SwiftNIO should be terms you can explain by now. Finally, you explored the features of Swift 5 and have seen examples of what the changes could look like in practice.
Go through the Questions section to validate your understanding of Swift on the server.
In the next chapter, you are going to explore the Vapor framework and you will be set up to create web applications with Vapor and Swift.
