Have you had experience developing backend applications using Vapor?

I have experience developing backend applications using Vapor — a Swift framework for creating server-side applications. For example, I built a REST API for a mobile app, using Vapor for routing, working with a database through Fluent, and handling requests. Here's a simple example of a request handler in Vapor:

import Vapor

func routes(_ app: Application) throws {
    app.get("hello") { req -> String in
        return "Hello, Vapor!"
    }
}

This approach allows writing backend in Swift, which is convenient for iOS developers.
