Building the user model

To be have a conversation you need to store some information about a user:

  • A user's name
  • A user's JWT
  • Who they are chatting with

To do this you will use a Struct. Open the ViewController.swift file and add it below the class.

class ViewController: UIViewController {

struct User {
    let name: String
    let jwt: String
    let callPartnerName: String

To make things easier for later on add some static properties on the User type for the users Alice and Bob. Replacing ALICE_USERID, ALICE_JWT, BOB_USERID, BOB_JWT with the values you created earlier.

struct User {

    static let Alice = User(name: "Alice",
                            callPartnerName: "Bob")
    static let Bob = User(name: "Bob",
                          callPartnerName: "Alice")
