Hello, since almost all my App data comes from HealthKit, I can't read the data in the Xcode simulator. Is there any way to synchronize the iPhone data to the simulator to help me test and find the cause of the problem?

Also, I have tried testing by directly linking the iPhone through Xcode, and there are no errors.

I caught the error on the real device through other methods, as follows: error: SwiftData.SwiftDataError(_error: SwiftData.SwiftDataError._Error.loadIssueModelContainer) But there is no more detailed information.

I tried using sysdiagnose but it was too hard for me. This is how I caught the error: import SwiftUI import HealthKit import SwiftData import os.log @main struct MeApp: App { @StateObject var viewModel = ViewModel() @StateObject private var entitlementManager: EntitlementManager @StateObject private var purchaseManager: PurchaseManager @StateObject var sessionManager = SessionManager() let colors: [Color] = [ .introGreen, .introBlue] @State var sharedModelContainer: ModelContainer? @State var crashInfo: String = "No Crash" // 初始化方法 init() { let entitlementManager = EntitlementManager() let purchaseManager = PurchaseManager(entitlementManager: entitlementManager) self._entitlementManager = StateObject(wrappedValue: entitlementManager) self._purchaseManager = StateObject(wrappedValue: purchaseManager) } var body: some Scene { WindowGroup { VStack{ if let container = sharedModelContainer{ ContentView() .environmentObject(viewModel) .environmentObject(queryData) .environmentObject(ringsDataQuery) .environmentObject(darkModeSettings) .environmentObject(recordsQuery) .environmentObject(sst) .environmentObject(hrQuery) .environmentObject(purchaseManager) .environmentObject(entitlementManager) .environmentObject(sessionManager) .modelContainer(container) .preferredColorScheme(darkModeSettings.isDarkModeEnabled ? .dark : nil) .task { await loadImage() await loadImage2() await purchaseManager.updatePurchasedProducts() sessionManager.startSession() } } else { VStack{ Image("Failed") .resizable() .scaledToFit() .frame(width: 100) Text("Er...There is something wrong.") .font(.system(size: 36)) .fontWeight(.bold) .multilineTextAlignment(.center) .foregroundStyle(LinearGradient(colors: colors, startPoint: .leading, endPoint: .trailing)) Text(crashInfo) .font(.system(size: 12)) .padding(20) } .padding(.horizontal,20) .preferredColorScheme(.dark) .transition(AnyTransition.move(edge: .bottom).animation(.spring(duration: 1.5))) .transition(AnyTransition.opacity.animation(.spring(duration: 1.5))) } } .onAppear{ let log = Logger(subsystem: "Kookybread.Me", category: "modelContainer") do { let schema = Schema([ HealthDataList.self, HealthDataStatistics.self, HeartZoneData.self, UserSettingTypeFor.self, SleepDataSource.self, SleepStagesData.self, SportsDataStatistics.self, TodayHealthData.self, TodayRingData.self, WorkoutDetailData.self, WorkoutHeartZoneData.self, WorkoutList.self, WorkoutMaxMinRangeData.self, WorkoutSegmentData.self, WorkoutStatisticsForTarget.self, WorkoutTargetData.self, AvatarImage.self, NickName.self ]) sharedModelContainer = try ModelContainer( for: schema, migrationPlan: MeMigrationPlan.self ) print("ModelContainer initialized successfully") } catch { log.error("Failed to initialize model container: \(error, privacy: .public)") crashInfo = "Error: \(error.self)" } } } } }

I have tried using ModelConfiguration to customize the location, and it seems that there is no error, but at the same time the widget cannot get the data. let storeURL = URL.documentsDirectory.appending(path: "MeDataBase.sqlite") let config = ModelConfiguration(url: storeURL)

I searched the Internet for a long time, and almost all of them are related to CloudKit, but I don't use anything related to CloudKit. Another thing is that I use some Codable structures and @Attribute(.unique) in the definition of some of my models. I wonder if this has any impact on this?

I tested in Xcode today and found that when the migration started, the NSStoreModelVersionHashesVersion of the previous version of the Schema seemed to always be "1.0.0". Although the Models corresponded to Schema.Version(3, 0, 0) ... CoreData: annotation: Incompatible version schema for persistent store 'file:///private/var/mobile/Containers/Shared/AppGroup/48F39567-A54A-45A6-B51F-EBB5064E488C/Library/Application%20Support/default.store'. store metadata = { NSPersistenceFrameworkVersion = 1345; NSStoreModelVersionChecksumKey = "m47Q+vHOr0gMrRL9ogWBvunjLYZwmfrt0PDX73TO/oA="; NSStoreModelVersionHashes = { HealthDataList = {length = 32, bytes = 0x27b73968 fe755a8f 28dd4224 1692184d ... e7762ec3 66e4f0fa }; HealthDataStatistics = {length = 32, bytes = 0x7b1c108d 3578e7df 22035d15 b4f2eadf ... 4e150ac4 337f17f8 }; SleepDataSource = {length = 32, bytes = 0x293b98b8 9ea8499c f7c61923 afd393a3 ... 7c034d3b d8928042 }; SportsDataStatistics = {length = 32, bytes = 0x0b67e997 dddfddbd 5b53cd40 c58993f5 ... 77064cd6 b53b1b1b }; TodayHealthData = {length = 32, bytes = 0xfb6de2ab 2fd504e6 88989a57 bb77a1a2 ... 56c03fca 0973076e }; TodayRingData = {length = 32, bytes = 0x2c0a63ed 7babcb9a d206cd3e 62a35ca8 ... ee3ca37a 14b3b9ce }; UserSettingTypeFor = {length = 32, bytes = 0xdc8b892a b46ce5b3 707263dd ba511389 ... d7899956 9e8d5890 }; WorkoutList = {length = 32, bytes = 0xe510f3ad 374714f1 2845e983 d1b53a9b ... 4761cabf 477ac79b }; WorkoutStatisticsForTarget = {length = 32, bytes = 0xe4e7fef0 daf11afe b9601a0f 5374446f ... 06e0be97 eccf372b }; WorkoutTargetData = {length = 32, bytes = 0x4f636c57 b8de4f32 5be80c23 1bb882a1 ... 655be445 20d96f1a }; }; NSStoreModelVersionHashesDigest = "Qq+tCNnYs1Cq87uFu98DSiOor6rB8Noz6mfrEGibCFWNe0Y3uRqyok4sbz4LVhYpHUl3tgw9jRw6rrm6iimpxA=="; NSStoreModelVersionHashesVersion = 3; NSStoreModelVersionIdentifiers = ( "1.0.0" ); NSStoreType = SQLite; NSStoreUUID = "4DB70733-02E9-4BD7-8037-05AE5EE3DEDA"; "_NSAutoVacuumLevel" = 2; } ...

I continued to test other versions. Before and after the migration, ModelVersionIdentifiers was always "1.0.0" init() { let schema = Schema([ WorkoutList.self, HealthDataStatistics.self, SportsDataStatistics.self, UserSettingTypeFor.self, TodayRingData.self, TodayHealthData.self, SleepDataSource.self, WorkoutTargetData.self, WorkoutStatisticsForTarget.self, HealthDataList.self, SleepStagesData.self, WorkoutDetailData.self, HeartZoneData.self, WorkoutSegmentData.self, WorkoutMaxMinRangeData.self, WorkoutHeartZoneData.self ]) do { container = try ModelContainer( for: schema, migrationPlan: MeMigrationPlan.self ) print("ModelContainer initialized successfully") print("container \(container.self)") print("containerVersion \(container.schema.version)") print("containerEncodingVersion \(container.schema.encodingVersion)") print("containerMigrationPlan \(container.migrationPlan)") print("containerConfigurations \(container.configurations)") } catch { print("Error initializing model container: \(error)") fatalError("Failed to initialize model container.") } } Log output after migration： ModelContainer initialized successfully container SwiftData.ModelContainer containerVersion 1.0.0 containerEncodingVersion 1.0.0 containerMigrationPlan Optional(Me.MeMigrationPlan) containerConfigurations [ModelConfiguration name: default url: file:///private/var/mobile/Containers/Shared/AppGroup/0D641150-923C-4A26-B908-1FCEA6012721/Library/Application%20Support/default.store allowsSave: true isStoredInMemoryOnly: false cloudKitDatabase: CloudKitDatabase(_automatic: true, _none: false, _privateDBName: nil) cloudKitContainerIdentifier: nil groupContainer: GroupContainer(_automatic: true, _none: false, _identifier: nil) groupAppContainerIdentifier: Optional("group.XXXXXXXXX.kookybread.me")]

I think I encountered the same problem as you.

I just tried logging an error.localizedDescription in TestFlight and got : Could not create ModelContainer: The operation couldn’t be completed. I also tried adding -com.apple.CoreData.MigrationDebug 1 to the launch arguments, but there was no "CoreData: error: ..." in the Xcode console. I created a new project and copied the MigraitonPlan-related code from my code into it and uploaded it to Github. TestDemo

This demo seems to report an error in xcode Could not create ModelContainer: The operation couldn’t be completed. But I checked it several times and couldn’t find the problem. In addition, when I run my app through xcode, there is no such error.
