Implementation Guidelines

State Management

• @State: Private UI state owned by the view (e.g., toggle, text input).
• @Binding: Two-way connection to parent's @State.
• @ObservedObject: Reference to external observable object.
• @StateObject: View owns the lifecycle of the object.
• @EnvironmentObject: Shared data across view hierarchy.

View Composition

• Extract Subviews: Keep views small (<200 lines). Extract reusable components.
• View Modifiers: Chain modifiers for styling (.font(), .padding()).
• Custom Modifiers: Create ViewModifier for reusable styles.
