State ownership, view identity, data flow, and compositional UI design for modern Apple platform teams.
Focus areas: State, identity, data flow, and compositional UI design
How do you implement MVVM in SwiftUI?
Contrast Combine-era ObservableObject MVVM with iOS 17+ @Observable MVVM, keeping the same Provider → ViewModel → View boundaries, DI, and testability rules
What is the difference between ObservableObject and @Observable in SwiftUI?
Compare Combine-era observation with the iOS 17 Observation system, focusing on invalidation granularity, boilerplate, and how ownership changes in SwiftUI
How do you decide between @State, @StateObject, @ObservedObject, and @EnvironmentObject?
StateObject vs ObservedObject comes down to ownership, so map each SwiftUI property wrapper to who owns the object rather than memorizing them in isolation
