SwiftUI NavigationStack State Sharing | Parent to Child ViewModel Explained

In this video, we dive deep into SwiftUI state management while navigating between views using NavigationStack.

You’ll learn:
• Why @State does NOT work across navigation
• How @StateObject and @ObservedObject actually behave
• How to share a ViewModel between parent and child views
• How NavigationStack preserves state
• Common SwiftUI mistakes that break data flow

We build a real counter example where:
– The parent view owns the ViewModel
– The child view updates the same state
– Changes reflect instantly across navigation

This is a MUST-WATCH if you are confused about SwiftUI state, navigation, or ViewModel lifecycles.
