Knew what MVC was but fumbled a bit explaining how the model and controller actually interact in practice.
Start by defining MVC as a design pattern that separates an application into three interconnected components: Model, View, and Controller. Then explain each component's responsibility and how they interact, using a concrete example like a simple to-do app. Finally, discuss trade-offs and variations (e.g., MVP, MVVM) to show depth, especially in the context of Apple's ecosystem.
Pro tip: Mention how Apple's frameworks like UIKit and SwiftUI relate to MVC (or MVVM), and acknowledge that while MVC is foundational, it can lead to massive view controllers—showing you understand real-world trade-offs.
State that MVC is an architectural pattern that divides an application into three main logical components: Model, View, and Controller, each with distinct responsibilities.
Describe the Model (data and business logic), View (UI presentation), and Controller (handles user input, updates Model and View). Emphasize separation of concerns.
Walk through a simple example, such as a user list: Model fetches users, Controller receives tap and updates Model, View displays the list.
Mention pros (modularity, testability) and cons (massive view controllers, tight coupling in some implementations). Briefly compare with MVVM or MVP.
Tie it to Apple's frameworks: UIKit follows MVC, SwiftUI leans toward MVVM. Show awareness of how Apple engineers apply these patterns.
