How do I separate view, view model, and model layers?

In this example, we will explore how to separate the view, view model, and model layers in a Swift application using the MVVM architecture.

        // Model
        struct User {
            var name: String
            var age: Int
        }

        // ViewModel
        class UserViewModel {
            private var user: User
            
            var userName: String {
                return user.name
            }
            
            var userAge: String {
                return "\(user.age) years old"
            }
            
            init(user: User) {
                self.user = user
            }
        }

        // View (Example User Interface)
        class UserView {
            var viewModel: UserViewModel
            
            init(viewModel: UserViewModel) {
                self.viewModel = viewModel
            }
            
            func displayUserInfo() {
                print("Name: \(viewModel.userName), Age: \(viewModel.userAge)")
            }
        }

        // Usage Example
        let user = User(name: "John Doe", age: 30)
        let viewModel = UserViewModel(user: user)
        let userView = UserView(viewModel: viewModel)
        userView.displayUserInfo() // Output: Name: John Doe, Age: 30 years old
