Thank you very much for the detailed answer — it really helped me understand the problem and find a working solution! I’m not sure if this is a bug or just how @Query is designed to work, but here’s what I found: In my case, I have three models: A, B, and C. Model A contains arrays of both B and C. Initially, I used @Query only to fetch model A, and then displayed the related B and C items from within it — but I did not fetch B and C directly with @Query: @Query var a: [A] var body: some View { ForEach(a) { item in item.B item.C } } After reading your explanation, I changed my code to fetch B and C directly using @Query, and then filtered them to include only those related to the specific A instance: @Query var a: [A] @Query var b: [B] @Query var c: [C] var body: some View { ForEach(a) { item in b.filter{$0.a == item} c.filter{$0.a == item} } } Now, when the widget updates a B or C object, the corresponding view in the app does update as expected — so your explanation about remote changes and @Query behavior was exactly what I needed. Thanks again!
