## 1. What is the main difference between NavigationStack and NavigationView in SwiftUI?

**Answer**

NavigationStack (iOS 16+) replaces NavigationView and provides explicit state management with NavigationPath. NavigationView uses an implicit navigation stack, while NavigationStack enables full programmatic control of navigation through bindable state.

## 2. What is the purpose of the navigationTitle modifier in SwiftUI?

**Answer**

The navigationTitle modifier sets the title displayed in the navigation bar when a view appears. It accepts a displayMode parameter to control the title's display style (inline, large). It is a key navigation interface element.

## 3. What is the correct method to create navigation to a destination with NavigationLink?

**Answer**

NavigationLink accepts a label (displayed view) and a destination (target view). In modern SwiftUI, prefer the initializer with value and navigationDestination modifier for better state management. NavigationLink shows a chevron indicator by default on iOS.
