Building the user model

To 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
• The conversation ID

To do this you will use a Struct. Open ViewController.swift and add it, replacing CONVERSATION_ID with the conversation ID created earlier:

class ViewController: UIViewController {
    ...
}

struct User {
    let name: String
    let jwt: String
    let chatPartnerName: String
    let conversationId = "CONVERSATION_ID"
}

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

struct User {
    ...

    static let Alice = User(name: "Alice",
                            jwt:"ALICE_JWT",
                            chatPartnerName: "Bob")
    static let Bob = User(name: "Bob",
                          jwt:"BOB_JWT",
                          chatPartnerName: "Alice")
}
