What are architecture patterns for Vision in Swift?

Architecture patterns for Vision in Swift involve structuring your application in a way that promotes clear separation of concerns, maintainability, and scalability. Some common architecture patterns include:

  • MVC (Model-View-Controller): This pattern separates the application into three interconnected components, allowing for efficient code organization and clearer data flow.
  • MVP (Model-View-Presenter): This pattern focuses on the presentation logic, where the Presenter handles the communication between the Model and View.
  • MVI (Model-View-Intent): A unidirectional data flow architecture that focuses on expressing state and actions more explicitly.
  • VIPER (View-Interactor-Presenter-Entity-Router): This pattern divides the application into distinct layers, aiming for high testability and low coupling.
  • SwiftUI & Combine: Utilizing SwiftUI for UI design and Combine for reactive programming, promoting a declarative approach in designing user interfaces.

Here's an example of a simple implementation using MVVM (Model-View-ViewModel) in Swift:

class User { var name: String var age: Int init(name: String, age: Int) { self.name = name self.age = age } } 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 } } // In a SwiftUI View struct UserView: View { @ObservedObject var viewModel: UserViewModel var body: some View { VStack { Text(viewModel.userName) Text(viewModel.userAge) } } }
