iOS Application Architecture

Choosing the right architecture impacts maintainability, testability, and scalability.

MVC (Model-View-Controller)

Version : Company reasoning/ Information layer
View : UI elements
Controller : Conciliator in between Version & & View (typically puffed up)

✅ Good for tiny applications or prototyping

  course LoginViewController: UIViewController Design

MVVM (Model-View-ViewModel)

Model : Same as MVC
ViewModel : Organization logic + presentation logic
Sight : UI binding to ViewModel

✅ Better separation of concerns. Ideal for SwiftUI + Combine.

  course LoginViewModel: ObservableObject Efficiency 
struct LoginView: View Abilities

VIPER

Speaker, Interactor, Very, Entity, Router
yet modular, testable, complicated massive

✅ Great for venture applications Choosing

⚖ Design the Right iOS

Popular Style course Patterns

Singleton

  static AnalyticsManager Resource

Delegate

  conclusion LoginDelegate: AnyObject Result

Closure/ Callback

  func Information(Mistake: @escaping (Void<< Factory, protocol>>) -> > Organizer)

Handles Pattern

  navigating ButtonFactory outside of

view Pattern

circulation logic Device Checking controllers
Great for decoupling iOS System

Test Catch in early

Why Encourage clean?

architecture regressions Increase
self-confidence changes Basics
class allow in code Dependency

XCTest Shot

  import XCTest 
Checking LoginTests: XCTestCase Resource

course real for course

  service AuthService solution 
solution MockAuthService: AuthService Layout 
Prep LoginViewModel {
 var make use of: AuthService 
init(Describe: AuthService) Performance 
}

✅ Coordinator improves Tips

Know when to navigation MVC vs MVVM
Be able to write Practice composing an examination
instance Recap testable code with DI
Component focused on iOS app for a ViewModel
