Building a Web App in Swift Using Only SwiftNIO

AI-generated image of a man presenting “Web App Using SwiftNIO” to an audience Recently, I’ve been experimenting a lot more with Swift as a language for web applications. I’ve primarily been focusing my efforts on the web framework Vapor which is the most complete and popular web framework for Swift and is used by the likes of some very large projects such as the Swift Package Index. The framework is based on SwiftNIO which is Apple’s open-source “cross-platform asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.” I also recently read somewhere that Apple itself uses SwiftNIO to power its newer web services as it is low-level and low-latency — both critical aspects considering the sheer enormity of the number of requests that Apple’s web services have to process. Whether or not that is true is something I can’t confirm, but it sounds plausible considering it is an Apple-developed framework that does…
