Swift 5.5 introduced Concurrency - async/await, structured concurrency, Actors, etc. greatly simplifying what it takes to write performant, safe, server side Swift code. Since the introduction of these features, many people have found Swift to be an excellent language for building server side applications, including Apple. Apple has made a strong push to make Swift fully available on Linux, and even built projects like the Swift AWS Lambda runtime. But even with the great support coming from Apple, depoloying server side Swift still takes a lot of operational expertise, and then even once deployed developers are missing those platform features that we have come to expect.
Swift Cloud aims to solve this problem by providing a platform that gives developers a robust set of features for deploying Swift to the cloud. Things like 1 click deploys, HTTP/3, globally distributed, 100ms cold starts, custom domains and more.
