I've noticed that SwiftData's @Relationship seems to potentially cause application crashes.
The crash error is shown in the image.
Since this crash appears to be random and I cannot reproduce it under specific circumstances, I can only temporarily highlight that this issue seems to exist.
@Model final class TrainInfo {
@Relationship(deleteRule: .cascade, inverse: \StopStation.trainInfo)
var stations: [StopStation]?
}
@Model final class StopStation {
@Relationship
var trainInfo: TrainInfo?
}
/// some View
var origin: StopStationDisplayable? {
if let train = train as? TrainInfo {
return train.stations?.first(where: { $0.isOrigin }) ?? train.stations?.first(where: { $0.isStarting })
}
return nil
}
// Some other function or property
func someFunction() {
if let origin, let destination {
// Function implementation
}
}
i want to save data like images, text,amd mapviews with swiftui. It is only saved but if you delete the app of buy a new iPhone everything is deleted, how can I make if that the information saved on my app is saved even after I update the app, delete the app, or put the app in another iPhone with SwiftUI? i have watched youtube videos and im still confused,please help.
error: the replacement path doesn't exist <- how bad is this error, should i care - is it important?
I get this error, i have my own DIKit, and i want to use swiftdata for showing info from persisten model. It works all over the app, but i get this error with my .sheet.

Definitely one of the stranger quirks of SwiftData I've come across.
I have a ScriptView that shows Line entities related to a Production, and a TextEnterScriptView that’s presented in a sheet to input text.
I’m noticing that every time I type in the TextEditor within TextEnterScriptView, a new Line shows up in ScriptView — even though I haven’t explicitly inserted it into the modelContext.
I'm quite confused because even though I’m only assigning a new Line to a local @State array in TextEnterScriptView, every keystroke in the TextEditor causes a duplicate Line to appear in ScriptView.
In other words, Why is SwiftData creating new Line entities every time I type in the TextEditor, even though I’m only assigning to a local @State array and not explicitly inserting them into the modelContext?
Here is my minimal reproducible example:
import SwiftData
import SwiftUI
@main
struct testApp: App {
var body: some Scene {
WindowGroup {
ContentView()
.modelContainer(for: Line.self, isAutosaveEnabled: false)
}
}
}
struct ContentView: View {
@Environment(\.modelContext) var modelContext
@Query(sort: \Production.title) var productions: [Production]
var body: some View {
NavigationStack {
List(productions) { production in
NavigationLink(value: production) {
Text(production.title)
}
}
.navigationDestination(for: Production.self) { production in
ScriptView(production: production)
}
.toolbar {
Button("Add", systemImage: "plus") {
let production = Production(title: "Test \(productions.count + 1)")
modelContext.insert(production)
do {
try modelContext.save()
} catch {
print(error)
}
}
}
.navigationTitle("Productions")
}
}
}
struct ScriptView: View {
@Query private var lines: [Line]
let production: Production
@State private var isShowingSheet: Bool = false
var body: some View {
List {
ForEach(lines) { line in
Text(line.content)
}
}
.toolbar {
Button("Show Sheet") {
isShowingSheet.toggle()
}
}
.sheet(isPresented: $isShowingSheet) {
TextEnterScriptView(production: production)
}
}
}
struct TextEnterScriptView: View {
@Environment(\.dismiss) var dismiss
@State private var text = ""
@State private var lines: [Line] = []
let production: Production
var body: some View {
NavigationStack {
TextEditor(text: $text)
.onChange(of: text, initial: false) {
lines = [Line(content: "test line", production: production)]
}
.toolbar {
Button("Done") {
dismiss()
}
}
}
}
}
@Model
class Production {
@Attribute(.unique) var title: String
@Relationship(deleteRule: .cascade, inverse: \Line.production)
var lines: [Line] = []
init(title: String) {
self.title = title
}
}
@Model
class Line {
var content: String
var production: Production?
init(content: String, production: Production?) {
self.content = content
self.production = production
}
}
SwiftData delete isn't working, when I attempt to delete a model, my app crashes and I get the following error:
SwiftData/PersistentModel.swift:359: Fatal error: Cannot remove My_App.Model2 from relationship Relationship - name: model2, options: [], valueType: Model2, destination: Model2, inverseName: models3, inverseKeypath: Optional(\Model2.models3) on My_App.Model3 because an appropriate default value is not configured.
I get that it's saying I don't have a default value, but why do I need one? Isn't @Relationship .cascade automatically deleting the associated models?
And onto of that, why is the error occurring within the do block, shouldn't it be caught by the catch, and printed?
I have put together a sample project below.
import SwiftUI
import SwiftData
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
.modelContainer(for: Model3.self)

Hi, would it be possible that instead of crashing when calling fetchHistory that function simply throws an error instead?
fetchHistory seems to crash when it cannot understand the models if they are not compatible etc… which is understandable, but it makes it really difficult to handle and debug, there's not a lot of details, and honestly I would just rather that it throws an error and let me ignore a history entry that might be useless rather than crashing the entire app.
Thank you!
I get this message when trying to save my Models.

Hi everyone
In the last 24 hours, I’ve been running into some issues with the CloudKit console.
Most of the time, I‘ll get an error stating an error has caused this web page to stop working correctly. Reloading doesn’t fix the issue, nor does using different browsers:
Today I’ve got another error, something along the lines of the Console not being able to fetch the teams I’m assigned to and an XHF error pop-up.
Has anyone encountered the same issues? After trying multiple times, I’m able to reach my database but it’s a bit frustrating as it’s very unreliable this way.
Thanks for your feedback!
Dave
I'm developing an app that uses CloudKit synchronization with SwiftData and on visionOS I added an App Settings bundle. I have noticed that sometimes, when the app is open and the user changes a setting from the App Settings bundle, the following fatal error occurs:
SwiftData/BackingData.swift:831: Fatal error: This model instance was destroyed by calling ModelContext.reset and is no longer usable.
The setting is read within the App struct in the visionOS app target using @AppStorage and this value is in turn used to set the passthrough video dimming via the .preferredSurroundingsEffect modifier. The setting allows the user to specify the dimming level as dark, semi dark, or ultra dark.
The fatal error appears to occur intermittently although the first time it was observed was after adding the settings bundle. As such, I suspect there is some connection between those code changes and this fatal error even though they do not directly relate to SwiftData.
Hi. I am having this error when trying to write to CloudKit public database.
<CKError 0x600000dbc4e0: "Permission Failure" (10/2007); server message = "Invalid bundle ID for container";
On app launch, I check for account status and ensure that the correct bundle identifier and container is being used. When the account status is checked, I do get the correct bundle id and container id printed in the console but trying to read or write to the container would throw that "Invalid bundle ID for container" error.
private init() {
container = CKContainer.default()
publicDB = container.publicCloudDatabase
// Check iCloud account status
checkAccountStatus()
}
func checkAccountStatus() {
print("🔍 CloudKit Debug:")
print("🔍 Bundle identifier from app: (Bundle.main.bundleIdentifier ?? "unknown")")
print("🔍 Container identifier: (container.containerIdentifier ?? "unknown")")
container.accountStatus { [weak self] status, error in
DispatchQueue.main.async {
switch status {
case .available:
self?.isSignedIn = true
self?.fetchUserID()
case .noAccount, .restricted, .couldNotDetermine:
self?.isSignedIn = false
self?.errorMessage = "Please sign in to iCloud in Settings to use this app."
default:
self?.isSignedIn = false
self?.errorMessage = "Unknown iCloud account status."
}
print("User is signed into iCloud: \(self?.isSignedIn ?? false)")
print("Account status: \(status.rawValue)")
}
}
}
I have tried:
Creating a new container
Unselecting and selecting the container in signing & capabilities
Unselecting and selecting the container in App ID Configuration
I used to have swift data models in my code and read that swift data is not compatible with CloudKit public data so I removed all the models and any swift data codes and only uses CloudKit public database.
let savedRecord = try await publicDB.save(record)
Nothing seems to work. If anyone could help please?
Rgds,
Hans

Hello Devs,
I'm encountering a persistent INTERNAL_ERROR (HTTP 500) when making Server-to-Server API calls to CloudKit, specifically when trying to hit the /users/current endpoint, even after meticulously verifying all client-side components. I'm hoping someone might have insight into what could cause this.
Context:
Goal: Authenticate to CloudKit from a Vercel Serverless Function (Node.js) to perform operations like record queries.
Problem Endpoint: POST https://api.apple-cloudkit.com/database/1/iCloud.com.dannybaseball.Danny-Baseball/production/public/users/current
Key Generation Method: Using the CloudKit Dashboard's "Tokens & Keys" -> "New Server-to-Server Key" flow, where I generate the private key using openssl ecparam -name prime256v1 -genkey -noout -out mykey.pem, then extract the public key using openssl ec -in mykey.pem -pubout, and paste the public key material (between BEGIN/END markers) into the dashboard. The private key was then converted to PKCS#8 format using openssl pkcs8 -topk8 -nocrypt -in mykey.pem -out mykey_pkcs8.pem.
Current Setup Being Tested (in a Vercel Node.js function):
CLOUDKIT_CONTAINER: iCloud.com.dannybaseball.Danny-Baseball
CLOUDKIT_KEY_ID: 9368dddf141ce9bc0da743b9f69bc3eda132b9bb3e62a4167e428d4f320b656e (This is the Key ID generated from the CloudKit Dashboard for the public key I provided).
CLOUDKIT_P8_KEY (Environment Variable): Contains the base64 encoded string of the entire content of my PKCS#8 formatted private key file.
Key Processing in Code:
const p8Base64 = process.env.CLOUDKIT_P8_KEY;
const privateKeyPEM = Buffer.from(p8Base64, 'base64').toString('utf8');
// This privateKeyPEM string starts with "-----BEGIN PRIVATE KEY-----" and ends with "-----END PRIVATE KEY-----"
const privateKey = crypto.createPrivateKey({ key: privateKeyPEM, format: 'pem' });
// This line SUCCEEDS without DECODER errors in my Vercel function logs.
Use code with caution.
JavaScript
Request Body for /users/current: "{}"
Signing String (message = Date:BodyHash:Path):
Date: Correct ISO8601 format (e.g., "2025-05-21T19:38:11.886Z")
BodyHash: Correct SHA256 hash of "{}", then Base64 encoded (e.g., "RBNvo1WzZ4oRRq0W9+hknpT7T8If536DEMBg9hyq/4o=")
Path: Exactly /database/1/iCloud.com.dannybaseball.Danny-Baseball/production/public/users/current
Headers:
X-Apple-CloudKit-Request-KeyID: Set to the correct Key ID.
X-Apple-CloudKit-Request-ISO8601Date: Set to the date used in the signature.
X-Apple-CloudKit-Request-SignatureV1: Set to the generated signature.
X-Apple-CloudKit-Environment: "production"
Content-Type: "application/json"
Observed Behavior & Logs:
The Node.js crypto.createPrivateKey call successfully parses the decoded PEM key in my Vercel function.
The request is sent to CloudKit.
CloudKit responds with HTTP 500 and the following JSON body (UUID varies per request):
{
"uuid": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"serverErrorCode": "INTERNAL_ERROR"
}
Use code with caution.
Json
This happens consistently. Previously, with other key pairs or different P8 processing attempts, I was getting AUTHENTICATION_FAILED (401) or local DECODER errors. Now that the key parsing is successful on my end with this current key pair and setup, I'm hitting this INTERNAL_ERROR.
Troubleshooting Done:
Verified Key ID (9368dddf...) is correct and corresponds to the key generated via CloudKit Dashboard.
Verified Container ID (iCloud.com.dannybaseball.Danny-Baseball) is correct.
Successfully parsed the private key from the environment variable (after base64 decoding) within the Vercel function.
Meticulously checked the signing string components (Date, BodyHash, Path) against Apple's documentation. Path format is /database/1////.
Ensured all required headers are present with correct values.
Local Node.js tests (bypassing Vercel but using the same key data and signing logic) also result in this INTERNAL_ERROR.
Question:
What could cause CloudKit to return an INTERNAL_ERROR (500) for a /users/current request when the client-side key parsing is successful and all request components (path, body hash for signature, date, headers) appear to conform exactly to the Server-to-Server Web Services Reference?
Are there any known subtle issues with EC keys generated via openssl ecparam (and then converted to PKCS#8) that might lead to this, even if crypto.createPrivateKey parses them in Node.js?
Could there be an issue with my specific Key ID or container that would manifest this way, requiring Apple intervention?
Any insights or suggestions would be greatly appreciated. I can provide more detailed logs of the request components if needed.
Thank you!
I am developing an app that uses CloudKit sharing. I recently upgraded my iPad to use 23A5336a. After that upgrade, I can no longer accept a share that is sent to me.
I have rebooted the iPad and logged out of the iCloud account and logged back in. Every time I get a share link and tap it, it says:
" The owner stopped sharing or your account (xxx) doesn't have permission to open it"
This same code, running on the iOS26 device can share with device running iOS18.
Is this a known defect? Anything I can do to help resolve this issue?
Good morning everyone!
Today I have a question about using SwiftData with CloudKit and Widgets. I recently set up my project for SwiftData and CloudKit synchronization, but for some reason, I’m not able to give my Widget access to this data. CloudKit works perfectly fine for my main app, but the Widget only shows placeholder data(the placeholder data which were defined in the get functions as catch, this is sure).
I have set the CloudKit capability for my Widget extension and tried fetching data with the get-functions in the code below. I also ensured that the data model files are members of the Widget extension target and that the Widget extension uses the same CloudKit container as the main app.
I wondered if it is possible and reasonable to save a copy of my CloudKit data in an App Group container, but in that case, the information shown in the Widget are not always up-to-date, so a solution that fetches data directly from CloudKit would be better. Has anyone had experience with this case? I couldn’t find much information about this problem online.
In the code below, many parts have been deleted or altered because they are not relevant to the problem, as they don’t fetch data. The variables, functions, and data models in the code may sometimes have German names, but I hope you can still understand it.
Thanks for your help!
struct Provider: AppIntentTimelineProvider {
//[Placeholder and snapshot]
func timeline(for configuration: ConfigurationAppIntent, in context: Context) async -> Timeline<CleverEntry> {

Something has caused my CloudKit queries to fail. On the dashboard I get an error message "Failed to execute query" when I try to "SORT BY" a field. The field is listed under Indexes as "sortable". For a different field, when I enter the field under "FILTER BY", and before I tap "Query", I get "No results". That field is listed under the Indexes as "queryable".
It used to work fine.
I have described this further, with screenshots at FB16114560
I've got an application built on top of SwiftData (+ CloudKit) which is published to App Store.
I've got a problem where on each app update, the data saved in the database is duplicated to the end user.
Obviously this isn't wanted behaviour, and I'm really looking forward to fixing it. However, given the restrictions of SwiftData, I haven't found a single fix for this.
The data duplication happens automatically on the first initial sync after the update. My guess is that it's because it doesn't detect the data already in the device, so it pulls all data from iCloud and appends it to the database where data in reality exists.
I'm experiencing a critical issue with SwiftData custom migrations where objects created during migration appear to be inserted successfully but aren't persisted or found by queries after migration completes. The migration logs show objects being created, but subsequent queries return zero results.
I'm migrating from schema version V2 to V2_5, which involves:
Renaming Person class to GroupData
Keeping the same data structure but changing the class name while keeping the old class.
Using a custom migration stage to copy data from old to new schema
Below is an extract of my two schema and migration plan:
Environment:
Xcode 16.0,
iOS 18.0,
Swift 6.0
SchemaV2
enum LinkMapV2: VersionedSchema {
static let versionIdentifier: Schema.Version = .init(2, 0, 0)
static var models: [any PersistentModel.Type] {
[AnnotationData.self, Person.self, History.self]
}
@Model
final class Person {
@Attribute(.unique) var id: UUID
var name: String
var photo: String
var requirement: String
var statue: Bool
var annotationId: UUID?
var number: Int = 0
init(id: UUID = UUID(), name: String = "", photo: String = "", requirement: String = "", status: Bool = false, annotationId: UUID? = nil, number: Int = 0) {
self.id = id
self.name = name
self.photo = photo
self.requirement = requirement
self.statue = status
self.annotationId = annotationId
self.number = number
}
}
}
Schema V2_5
static let versionIdentifier: Schema.Version = .init(2, 5, 0)
static var models: [any PersistentModel.Type] {
[AnnotationData.self, Person.self, GroupData.self, History.self]
}
// Keep the old Person model for migration
@Model
final class Person {
@Attribute(.unique) var id: UUID
var name: String
var photo: String
var requirement: String
var statue: Bool
var annotationId: UUID?
var number: Int = 0
init(id: UUID = UUID(), name: String = "", photo: String = "", requirement: String = "", status: Bool = false, annotationId: UUID? = nil, number: Int = 0) {
self.id = id
self.name = name
self.photo = photo
self.requirement = requirement
self.statue = status
self.annotationId = annotationId
self.number = number
}
}
// Add the new GroupData model that mirrors Person
@Model
final class GroupData {
@Attribute(.unique) var id: UUID
var name: String
var photo: String
var requirement: String
var status: Bool
var annotationId: UUID?
var number: Int = 0
init(id: UUID = UUID(), name: String = "", photo: String = "", requirement: String = "", status: Bool = false, annotationId: UUID? = nil, number: Int = 0) {
self.id = id
self.name = name
self.photo = photo
self.requirement = requirement
self.status = status
self.annotationId = annotationId
self.number = number
}
}
}
Migration Plan
static let migrationV2toV2_5 = MigrationStage.custom(
fromVersion: LinkMapV2.self,
toVersion: LinkMapV2_5.self,
willMigrate: { context in
do {
let persons = try context.fetch(FetchDescriptor<LinkMapV2.Person>())
print("=== MIGRATION STARTED ===")
print("Found \(persons.count) Person objects to migrate")
guard !persons.isEmpty else {
print("No Person data requires migration")
return
}
for person in persons {
print("Migrating Person: '\(person.name)' with ID: \(person.id)")
let newGroup = LinkMapV2_5.GroupData(
id: person.id, // Keep the same ID
name: person.name,
photo: person.photo,
requirement: person.requirement,
status: person.statue,
annotationId: person.annotationId,
number: person.number
)
context.insert(newGroup)
print("Inserted new GroupData: '\(newGroup.name)'")
// Don't delete the old Person yet to avoid issues
// context.delete(person)
}
try context.save()
print("=== MIGRATION COMPLETED ===")
print("Successfully migrated \(persons.count) Person objects to GroupData")
} catch {
print("=== MIGRATION ERROR ===")
print("Migration failed with error: \(error)")
}
},
didMigrate: { context in
do {
// Verify migration in didMigrate phase
let groups = try context.fetch(FetchDescriptor<LinkMapV2_5.GroupData>())
let oldPersons = try context.fetch(FetchDescriptor<LinkMapV2_5.Person>())
print("=== MIGRATION VERIFICATION ===")
print("New GroupData count: \(groups.count)")
print("Remaining Person count: \(oldPersons.count)")
// Now delete the old Person objects
for person in oldPersons {
context.delete(person)
}
if !oldPersons.isEmpty {
try context.save()
print("Cleaned up \(oldPersons.count) old Person objects")
}
// Print all migrated groups for debugging
for group in groups {
print("Migrated Group: '\(group.name)', Status: \(group.status), Number: \(group.number)")
}
} catch {
print("Migration verification error: \(error)")
}
}
)
And I've attached console output below:
