iOS Swift - State Management in SwiftUI
You have a parent view that owns a @StateObject called settings. You want to pass this object to a child view so it updates when settings changes. Which is the best way to do this?
AUse <code>@State</code> in the child view to hold <code>settings</code>
BDeclare <code>@StateObject</code> again in the child view for <code>settings</code>
CPass <code>settings</code> as an <code>@ObservedObject</code> parameter to the child view
DPass a copy of <code>settings</code> to the child view without property wrappers
Step-by-Step Solution
Solution:
Step 1: Understand ownership and passing rules
The parent view owns the @StateObject. The child view should observe it without owning it.
Step 2: Choose correct property wrapper for child
The child view uses @ObservedObject to observe changes without owning the object.
Step 3: Avoid re-declaring @StateObject in child
Declaring @StateObject again in child creates a new instance, breaking shared state.
Final Answer:
Pass settings as an @ObservedObject parameter to the child view -> Option C
