Hi, Overview I am using Xcode Cloud for my multi platform app. The macOS test case fails, however the iOS test case runs and succeeds. I don't have any UI test cases written, the test case are simple and have nothing platform (macOS) specific. Questions What can I do to fix this? Is there any user privileges needed to launch the macOS app for testing? I ask because when I ran the UI tests locally it launched the app and asked for my macOS user password. Just wondering if that is the reason it didn't launch in Xcode Cloud. Error: <Appname> encountered an error (Failed to install or launch the test runner. If you believe this error represents a bug, please attach the result bundle at /Volumes/workspace/resultbundle.xcresult.(Underlying Error: Could not launch "AppnameTests.

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?

Hi, Problem I have a widget which displays a bright red. When I display the same view inside the app, the red is bright. However when I use the same view on the widget, the color looks a bit dull. Note: Widget Style: Default (Always) It is the same dull red when in focus and when not in focus This happens on iOS (device and simulator) and macOS Questions How can I fix it on the widget? Does widget support Display P3 colors? Any help on this would be much appreciated.

Hi, I have listed below the Feedbacks for Xcode 27, please have a look at it, considerable time was spent on filing these feedbacks, thanks!

Hi, In the calendar app I created an event called E1 on an iCloud calendar and noticed 2 entries, so I suspect EKEventStore.events(matching:) returned it. Note: I am not referring to recurring events. Used an iCloud calendar Question Is it possible EKEventStore.events(matching:) to return duplicate events? When I did search the following was reported by AI, but I am not very sure, so hence the question. The EKEventStore.events(matching:) method returning duplicate events is a well-known, expected behavior in EventKit. It typically happens because a single event exists across multiple calendars, has multiple participants/invitees, or EventKit is fetching the event from different sync sources (like iCloud and a local cache) simultaneously.

Hi, Overview I am finding #Predicate to be a bit tricky when used with Swift Data It compiles fine but crashes at runtime I know the fix for the problem just wondering if such pitfalls can be avoided at compile time Exception *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'can't use NULL on left hand side' terminating due to uncaught exception of type NSException CoreData: error: SQLCore dispatchRequest: exception handling request: <NSSQLFetchRequestContext: 0x11209b000> , can't use NULL on left hand side with userInfo of (null) Questions Could anything be done to improve the safety to avoid such issues at runtime? Could I write the code better (better than the fix below) to avoid this? My thoughts Fix is possible however it wasn't obvious to me that there was a problem with my original code Would be nice to prevent them at compile time if possible. Currently got to be really careful to avoid such crashes. Code import Foundation import SwiftData @Model class Car { var name: String var modelRawValue: String? init(name: String, modelRawValue: String?) { self.name = name self.modelRawValue = modelRawValue } } enum CarModel: String, CaseIterable { case modelA case modelB } func makePredicate(filterModels: [CarModel]?) -> Predicate<Car> { let filterRawValues = filterModels?.map { $0.rawValue } let predicate = #Predicate<Car> { car in if let filterRawValues { if let carModelRawValue = car.modelRawValue { filterRawValues.contains(carModelRawValue) } else { false } } else { true } } return predicate } func fetch(context: ModelContext) throws { let predicate = makePredicate(filterModels: nil) let fetchDescriptor = FetchDescriptor(predicate: predicate) do { let cars = try context.fetch(fetchDescriptor) print(cars.count) } catch { print("Error: \(error)") throw error } } Fix func makePredicate(filterModels: [CarModel]?) -> Predicate<Car> { // Checking nil condition even before creating the predicate fixes the issue guard let filterModels else { return .true } let filterRawValues = filterModels.map { $0.rawValue } let predicate = #Predicate<Car> { car in if let carModelRawValue = car.modelRawValue { filterRawValues.contains(carModelRawValue) } else { false } } return predicate }

Hi, Overview I have an app for which I have created a sandbox account. When I try to clear purchase history it doesn't work, it still shows the in-app purchase items (non-consumable in-app purchases) as purchased. I have tied tried the following ways, but none of them work. Any help on this would be much appreciated! Attempt 1: Go to https://appstoreconnect.apple.com/ Users and Access > Sandbox Check sandbox account > Tap Clear Purchase History button Attempt 2: Go to the iPhone > Settings > Developer > Sandbox Apple Account Tap on account > Manage > Clear Purchase History Attempt 3: Sign out of Sandbox account and sign back in Attempt 4: Delete app and re-run app from Xcode

Hi, Overview: I have a project in which: Some files are only in the app target Some files are only in the widget target Some files are in the app and widget target (both targets) Now I would like to add string catalog for localization where strings would automatically detected from the project. Questions: Should I add a separate strings catalog for app target and widget target? What about the code shared between the 2 targets, do I have to do the translations twice for strings corresponding to files belonging to both app and widget target? What is the best approach for my project?

Overview When the macOS app is closed, the os logs (debug) logs are not visible in the Console app. However even when the iOS app is closed / killed, the os logs (debug) logs are visible in the Console app. What I have tried Console app menu Action > Include Debug Messages is checked Searched by subsystem Created a macOS app from the archive by choosing selecting Debugging option Note OS debug logs are visible when the macOS app is open Questions How can I make macOS debug logs visible in the Console app when the Mac app is closed? Should I be searching by some other fields? Or is there any other alternative / workaround this because I need to debug this scenario when app is closed?
