This project demonstrates how to use Swift as a programming language for building microservices, Kitura as a web framework, and Redis as a database. The author created a new Swift project, installed the necessary dependencies, including Kitura and a client library for interacting with Redis, and then built an HTTP server that connects to a Redis database in the cloud. The application sets a key-value pair in the Redis database and retrieves it, showcasing the ease of use of these technologies together.
