This document discusses Swift development on IBM Cloud. It summarizes Swift's performance and memory usage, introduces the Kitura web framework, and describes tools like the Swift Sandbox and Package Catalog for community enablement. An example photo sharing app called BluePic is presented to illustrate end-to-end Swift development, with the iOS client communicating with backend services hosted on IBM Cloud.
