iOS Swift - State Management in SwiftUI

What is wrong with this code snippet?

struct ContentView: View {
  @EnvironmentObject var settings: Settings
  var body: some View {
    VStack {
      Text(settings.username)
    }
  }
}

// Usage
ContentView().environmentObject(Settings())

ASettings must be a class conforming to ObservableObject.

BThe @EnvironmentObject property wrapper requires initialization.

CText cannot display a String directly.

DenvironmentObject() modifier should be applied to ContentView's parent, not ContentView itself.

Step-by-Step Solution

Solution:

Step 1: Check environmentObject injection location
The .environmentObject() modifier should be applied on a parent view, not directly on ContentView instance.
Step 2: Verify other options
Settings must be ObservableObject (assumed correct), Text can display String, and @EnvironmentObject does not require initialization.
Final Answer:
environmentObject() modifier should be applied to ContentView's parent, not ContentView itself. -> Option D
Quick Check:
Inject environment object on parent view [OK]

Quick Trick: Apply .environmentObject() on parent views, not on the view itself [OK]

Common Mistakes:
