SwiftUI for Production
summary
built the RayWenderlich iOS app with SwiftUI and implements a content-filter UI, but shows concrete pitfalls: binding to array elements causes crashes, enumerated ForEach is fragile, and environment/observed objects act like singletons. The implementation experiments with @State, @Binding, @ObservedObject and @EnvironmentObject, hits compiler/Apple bugs, then abandons deep bindings and replaced bindings with callbacks to mutate filter state safely; the final filter list works reliably after that change.
