SwiftUI List: observable reference types not deallocated immediately after refresh
Hello 👋 I ran into a SwiftUI lifecycle gotcha while debugging a List with .refreshable I share the code used to reproduce the issue @Observable final class CounterModel: Identifiable { let id: String var title: String var value: Int init(id: String, title: String, value: Int = 0) { self.id = id self.title = title self.value = value } deinit { print("deinit", title) } } @Observable final class ObservableCountersStore { var counters: [CounterModel] = [ .init(id: "1", title: "A"), .init(id: "2", title: "B"), .init(id: "3", title: "C") ] func refresh() async { try? await Task.sleep(nanoseconds: 300_000_000) counters = [.init(id: "4", title: "D")] } } struct ObservableCountersListView: View { @State private var store = ObservableCountersStore() var body: some View { List { ForEach(store.counters) { counter in ObservableCounterRow(counter: counter) } } .refreshable { await store.refresh() } } } struct ObservableCounterRow: View { let counter: CounterModel var body: some View { Text(counter.title) } } Observation: After calling refresh(), only some of the previous CounterModel only one CounterModel is deallocated immediately. Others are retained This doesn’t look like a leak, but it made me realize that passing observable reference types directly into List rows leads to non-deterministic object lifetimes, especially with .refreshable. Posting this as a gotcha — curious if this matches intended behavior or if others have run into the same thing.
