Problem When a List / Form is added inside a TabView and navigationTitle is set, then switching between tabs causes the navigation title to flicker. Feedback: FB21436493 Environment Xcode: 26.2 (17C52) iOS: 26.2 (23C55) Reproducible on: Both simulator and device Root cause When List / Form is commented out, issue doesn't occur Steps to Reproduce Run app on iOS Switch between tabs Notice that the navigation title flickers Code ContentView import SwiftUI struct ContentView: View { @State private var selectedTab = TabItem.red var body: some View { NavigationStack { TabView(selection: $selectedTab) { ForEach(TabItem.allCases, id: \.self) { tab in Tab(tab.rawValue, systemImage: tab.systemImageName , value: tab) { // Problem occurs with a List / Form // Commenting out list works without flickering title List { Text(tab.rawValue) } } } } .navigationTitle(selectedTab.rawValue) } } } TabItem enum TabItem: String, CaseIterable { case red case green case blue var systemImageName: String { switch self { case .red: "car" case .green: "leaf" case .blue: "bus" } } } Screen recording:

Overview I have a custom type Statistics that has 3 properties inside it I am trying to return this as part of the AppIntent's perforrm method struct Statistics { var countA: Int var countB: Int var countC: Int } I would like to implement the AppIntent to return Statistics as follows: func perform() async throws -> some IntentResult & ReturnsValue<Statistics> { ... ... } Problem It doesn't make much sense to make Statistics as an AppEntity as this is only computed as a result. Statistics doesn't exist as a persisted entity in the app. Questions How can I implement Statistics? Does it have to be AppEntity (I am trying to avoid this)? (defaultQuery would never be used.) What is the correct way tackle this?

Hi, I have created an AppIntent in which there is a parameter called price, I have set the default value as 0. @Parameter(title: "Price", default: 0) var price: Int Problem When the shortcut is run this parameter is skipped Aim I still want to price to be asked however it needs to be pre-filled with 0 Question What should I do that the shortcut can still ask the price but be pre-filled with 0?

Hi I have an Xcode project in which I am logging (os log) some faults when an error occurs. While developing I would like to notice it when the fault occurs. Questions Are there are better approaches to be alerted (sound or other means) when a fault occurs? My attempts so far: Add fault log and filter for faults Add breakpoint and play sound when breakpoint encountered Disadvantages with fault filtering: Though I can filter for faults sometimes I often need to look at debug messages. Having a lot of debug messages I am lost, yes I can filter but might forget to do it during every build Disadvantages with breakpoints: Sometimes I tend to delete breakpoints and might accidentally delete this breakpoint to play a sound

Hi, Overview: I get the following error when trying to save / read from SwiftData It happens when I try to save color to SwiftData (code below) Error 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release Questions How can I resolve the error? I am not directly using data, I am using just Float values, swift types. Why am I getting this error? Is there a way to add a breakpoint to stop at the exact type causing the error? (Symbolic breakpoint doesn't seem to help) Or is the below code ok and not responsible for the error? Code import SwiftUI nonisolated struct ColorRepresentation: Codable { let red: Float let green: Float let blue: Float let opacity: Float init(colorResolved: Color.Resolved) { red = colorResolved.red green = colorResolved.green blue = colorResolved.blue opacity = colorResolved.opacity } func color() throws -> Color { Color( red: Double(red), green: Double(green), blue: Double(blue), opacity: Double(opacity) ) } } extension ColorRepresentation: Equatable {}

Hi, Overview I have a SwiftData project which automatically syncs with CloudKit. When I run the app, I see the following error in Xcode logs. Error updating background task request: Error Domain=BGSystemTaskSchedulerErrorDomain Code=3 "(null)" My attempt I can enable Background processing (under Signing & Capabilities > Background modes), but I don't know the BGTaskSchedulerPermittedIdentifiers to add in the Info.plist Questions How can I resolve this? If I should enable background processing, what are the BGTaskSchedulerPermittedIdentifiers to add in Info.plist?
