Hands-On Swift 5 Microservices Development

Returning DB models

To return the user model is relatively simple: create a new instance of the output model and assign the values to it. Thanks to Swift's extensions, you can do it like this:

extension UserOutput {    init(withUser user: User, accessToken: String, refreshToken: String) {        self.userId = user.id        self.email = user.email        self.firstname = user.firstname        self.lastname = user.lastname        self.accessToken = accessToken        self.refreshToken = refreshToken    }}

To return the user, we now only have to call the following:

return UserOutput(withUser: user, ...)

We will complete these models in Chapter 7, Writing the User Service, when we write the User Manager Service.
