iOS Swift - State Management in SwiftUI

You want to share a user profile object across multiple views using @EnvironmentObject. Which steps must you follow to correctly implement this shared state? A) Declare the profile class as ObservableObject with @Published properties. B) Create an instance of the profile and inject it using .environmentObject() at the app root. C) Use @EnvironmentObject in all views that need access to the profile. D) Pass the profile instance manually to each view initializer instead of using @EnvironmentObject.

AOnly A, B, and C are needed.

BOnly B, C, and D are needed.

COnly A and B are needed.

DAll A, B, C, and D are needed.

Step-by-Step Solution

Solution:

Step 1: Identify correct steps for shared state
The profile class must conform to ObservableObject with @Published properties (A). Then create and inject it at the app root with .environmentObject() (B). Views needing access use @EnvironmentObject (C).
Step 2: Understand why D is incorrect
Passing the profile manually (D) defeats the purpose of @EnvironmentObject, which avoids manual passing.
Final Answer:
Only A, B, and C are needed. -> Option A
Quick Check:
ObservableObject + inject + @EnvironmentObject = C [OK]

Quick Trick: Inject once, declare ObservableObject, use @EnvironmentObject in views [OK]

Common Mistakes:

Passing environment object manually defeats its purpose
Forgetting to mark class ObservableObject
Not injecting at app root
