SwiftUI List performance

Dear Support Team, I am writing to seek technical assistance regarding a persistent issue with Dolby Vision exporting in DaVinci Resolve 20 on my iPad Pro 12.9-inch (2021, M1 chip) running iPadOS 26.0.1. The Issue: Despite correctly configuring the project for a Dolby Vision workflow and successfully completing the dynamic metadata analysis, the Dolby Vision Profile dropdown menu (and related embedding options) is completely missing from the Advanced Settings in the Deliver page. My Current Configuration & Steps Taken: Software Version: DaVinci Resolve Studio 20 (Studio features like Dolby Vision analysis are active and functional). Project Settings: Color Science: DaVinci YRGB Color Managed. Dolby Vision: Enabled (Version 4.0) with Mastering Display set to 1000 nits. Output Color Space: Rec.2100 ST2084. Color Page: Dynamic metadata analysis has been performed, and Trim controls are functional. Export Settings: Format: QuickTime / MP4. Codec: H.265 (HEVC). Encoding Profile: Main 10. The Problem:

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) } } Obse

1/ Issue Summary In our application, we use HKObserverQuery together with:HKHealthStore.enableBackgroundDelivery(for:frequency: .immediate) to enable HealthKit Background Delivery, allowing the system to wake our App Extension in the background to process health data updates. Under the same app build, identical HealthKit permission configuration, and the same watchOS version, we have observed significant differences in background delivery frequency across different devices. Specifically, on certain devices (e.g. Apple Watch Series 10, watchOS 26.2.1), the background delivery frequency is significantly reduced, behaving as if it is capped at approximately once per hour. On other control devices, under the same configuration, background delivery is triggered much more frequently and consistently, at approximately every 8–16 minutes. This behavior is consistently reproducible on the affected devices. **We would like to understand whether there are any officially recommended implementation patterns, best practice

Hi Everyone. Can you help me with my settings icon design. I'm trying to create a circular settings button using Menu. My code here: struct MenuView: View { var body: some View { Menu { Text(Hello) Text(How are you) } label: { Image(systemName: gearshape.fill) .clipShape(Circle()) } .clipShape(Circle()) .padding(.top, 10) .padding(.leading, 20) } } You can see my try, this one looks wrong. It should be like this: Just Circle with setting image inside. Thank you an advance 😭🙏🛐

Hi there, I just re-install 26.2, but I got many issues regarding to SwiftUI's components. How can I fix it? Do I need download or install something else?
