What are some examples of the MVC pattern in Swift?

The MVC (Model-View-Controller) pattern is widely used in Swift for organizing code. For example, in an iOS app, the Model could represent data like user profiles, the View could be the UI components displaying this data, and the Controller would handle the logic connecting the Model and View.

Can you give me a specific code example?

Sure! Here's a simple example:

class User {
    var name: String
    var age: Int
    init(name: String, age: Int) {
        self.name = name
        self.age = age
    }
}

class UserView {
    func displayUser(user: User) {
        print("User: \(user.name), Age: \(user.age)")
    }
}

class UserController {
    var user: User
    var view: UserView
    init(user: User, view: UserView) {
        self.user = user
        self.view = view
    }
    func updateUser(name: String, age: Int) {
        user.name = name
        user.age = age
        view.displayUser(user: user)
    }
}

In this example, User is the Model, UserView is the View, and UserController is the Controller.

How does this pattern help in app development?

The MVC pattern helps in separating concerns, making the code more organized and maintainable. It allows developers to work on different components independently, which can speed up development and make it easier to manage changes.
