Kitura-Session 3.3: Sharing Codable objects between a user’s requests

In Kitura-Session 3.3, by defining the type we expect from the session, we get our Codable model straight out of the session:

router.get("/session") { request, response, next in     let books: [Book] = request.session?["books"] ?? []     response.send(books)     next() }

Even with a simple model, this has vastly reduced the amount of code required, added compile time safety and made our code easier to read!
