I tried posting a request to my localhost with a json body from REST CLIENT & POSTMAN and also from terminal. But always the request.body is nil. Using package : .Package(url: "https://github.com/IBM-Swift/Kitura", majorVersion: 1, minor: 1).
Please make sure that you have added the BodyParser middleware to your routes. For example:
let router = Router()
router.all(middleware: BodyParser())
