The Observation framework has brought native property-level observation to Swift, effectively preventing unnecessary view updates in SwiftUI triggered by unrelated property changes, thereby enhancing application performance. However, since @State does not offer a lazy initialization constructor like @StateObject, it may lead to performance degradation or even logical issues due to the premature construction of instances in certain scenarios. This article explores how to implement a lazy initialization solution for Observable instances using @State.
