AltConf 2017: Full Stack Swift in 30 Minutes

The introduction of Swift on the server gave the promise of being able to easily build, deliver and own the whole user experience and the solution, not just the iOS app. Building a backend however introduces many new technologies and terms, from server, cloud and Swagger definitions, to Docker and Kubernetes. This session will show you how easy it can be, demonstrating how to build a Swift Server application and connect to it from an iOS app in under 30 minutes.
