End-To-End Application Development with Swift The addition of support for Swift as a server-side programming language makes it possible to use not just the same language on client and server, but also to reuse APIs and code. This opens up a world of possibilities for creating and deploying new types of applications. This session will introduce you to new models of client and server interaction for application development, and show you how to rapidly build an app with both client and server components written in Swift.
