“SwiftData inheritance relationship”

Hello everyone, When I press Control + Space on my Bluetooth keyboard to trigger input method switching, the accessory view fails to appear. This prevents me from quickly identifying the current input method type. Upon inspecting the View Hierarchy, I noticed that UICursorAccessoryView is not being created. For context, my input method responder inherits from UIResponder and conforms to the UITextInputTraits, UIKeyInput, and UITextInput protocols. The accessory view displays normally during accented input and Chinese input. Could you please guide me on how to troubleshoot this issue?

There is a conflict in SwiftData (specifically when synced with CloudKit) when a @Model attribute shares the same name as a case within its assigned enum type. When this occurs, accessing the attribute on a model instance consistently returns the value corresponding to the enum case name, rather than the actual value persisted in the database. Steps to Reproduce Define an enumeration (e.g., Status) with a case that matches a planned property name (e.g., case status). Create a SwiftData @Model that uses this enum. Name the property in the model the same as the enum case. Attempt to save and then retrieve the value. Example Code enum TaskStatus: String, Codable { case status // The conflict source case pending case completed } @Model class TodoItem { // Conflict: Property name matches enum case name var status: TaskStatus init(status: TaskStatus) { self.status = status } } Expected Behavior The property item.status should return the value stored in the database (e.g., .pending or .completed).

Hi, I’m implementing a macOS DNS Proxy as a system extension and running into a persistent activation error: OSSystemExtensionErrorDomain error 9 (validationFailed) with the message: extension category returned error This happens both on an MDM‑managed Mac and on a completely clean Mac (no MDM, fresh install).

Hey everyone I just ran into an issue where I couldn't sync the model below fully by using CloudKit, enum LinkMapV3_1: VersionedSchema { static let versionIdentifier: Schema.Version = .init(3, 1, 0) static var models: [any PersistentModel.Type] { [AnnotationData.self, GroupData.self, Item.self, Deployment.self, History.self] } // MARK: - Data @Model class AnnotationData { var name: String = var longitude: Double = 0.0 var latitude: Double = 0.0 var order: Int = -1 var level: Int = 1 var detail: String = @Relationship(deleteRule: .nullify, inverse: GroupData.annotation) var groups: [GroupData]? @Relationship(deleteRule: .nullify, inverse: AnnotationData.to) var from: AnnotationData? var to: AnnotationData? var history: History? } // MARK: - History @Model class History { var id: UUID = UUID() var timestamp: Date = Date() @Relationship(deleteRule: .nullify, inverse: AnnotationData.history) var annotations: [AnnotationData]? @Relationship(deleteRule: .nullify, inverse: Group

I'm setting up App Entities for my SwiftData models and I'm not sure about the best way to reference SwiftData model properties in the AppEntity. I have a SwiftData model with many properties: @Model final class Contact { @Attribute(.unique) var id: UUID = UUID() var name: String var phoneNumber: String var email: String var website: URL? var birthday: Date? var notes: String // ... many more properties } I want to expose these properties on my AppEntity so they're available for system features, such as giving Apple Intelligence more context about on-screen content. struct ContactEntity: AppEntity { var id: UUID @Property(title: Name) var name: String @Property(title: Phone) var phoneNumber: String @Property(title: Email) var email: String // ... all the other properties } I couldn't find guidance in the documentation for this specific situation. I've considered two approaches: Add @Property variables to the AppEntity for each SwiftData model property and copy all values fr

Hi all, I have setup my app to use SwiftData with CloudKit sync. I have a production environment and development environment. I can reset the development environment for myself and all users in CloudKit console, but I can't reset the production one as it's tried to users' iCloud accounts, so I've added a button in-app for that feature. In the onboarding of my app, I pre-seed the DB with some default objects, which should be persisted between app install. The issue I'm running into is that I'm unable to force-pull these models from iCloud during the onboarding of a clean re-install, which leads to the models later appearing as duplicates once the user has been on the app for a few minutes and it has pulled from their iCloud account. If anyone has any suggestions on how to handle this issue, I would greatly appreciate it.

I was wondering if errors are common for the code below for saving SwiftData data and what would be the best way to handle them (popup, closing the app)? do { try modelContext.save() } catch { print(error) }

I have SwiftData models containing arrays of Codable structs that worked fine before adding CloudKit capability. I believe they are the reason I started seeing errors after enabling CloudKit. Example model: @Model final class ProtocolMedication { var times: [SchedulingTime] = [] // SchedulingTime is Codable // other properties... } After enabling CloudKit, I get this error logged to the console: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release CloudKit Console shows this times data as plain text instead of bplist format. Other struct/enum properties display correctly (I think) as bplist in CloudKit Console. The local SwiftData storage handled these arrays fine - this issue only appeared with CloudKit integration. What's the recommended approach for storing arrays of Codable structs in SwiftData models that sync with CloudKit?

Hi everyone, In the simple app below, I have a QueryView that has LazyVStack containing 100k TextField's that edit the item's content. The items are fetched with a @Query. On launch, the app will generate 100k items. Once created, when I press any of the TextField's , a severe hang happens, and every time I type a single character, it will cause another hang over and over again. I looked at it in Instruments and it shows that the main thread is busy during the duration of the hang (2.31 seconds) updating QueryView. From the cause and effect graph, the update is caused by @Observable QueryController .(Bool). Why does it take too long to recalculate the view, given that it's in a LazyVStack? (In other words, why is the hang duration directly proportional to the number of items?) How to fix the performance of this app? I thought adding LazyVStack was all I need to handle the large dataset, but maybe I need to add a custom pagination with .fetchLimit on top of that? (I understand that ModelActor would be an alter
