“SwiftData inheritance relationship”

Question detail Dear Apple Developer Technical Support, We are currently following the official Apple documentation “TN3159: Migrating Sign in with Apple users for an app transfer” to carry out a Sign in with Apple user migration after successfully transferring several apps to a new developer account. Here is a summary of our situation: Under the original Apple developer account, we had five apps using Sign in with Apple, grouped under a shared primary app using App Grouping. Recently, we transferred three of these apps to our new Apple developer account via App Store Connect. After the transfer, these three apps are no longer associated with the original primary App ID. We reconfigured individual Services IDs for each app in the new account and enabled Sign in with Apple for each. More than 24 hours have passed since the app transfer was completed. Now we are attempting to follow the migration process to restore user access via the user.migration flow. Specifically, we are using the following script to reque

Although I can't see anything in Apple's documentation to this effect, I'm coming to believe that ReferenceFileDocument is incompatible with @Observable. But hopefully I've just missed something! I have an app in which the data model is @Observable, and views see it through @Environment(dataModel.self) private var dataModel Since there are a large number of views, only some of which may need to be redrawn at a given time, Apple's documentation leads me to believe that @Observable may be smarter about only redrawing views that actually need redrawing than @Published and @ObservedObject. I originally wrote the app without document persistence, and injected the data model into the environment like this: @main struct MyApp: App { @State private var dataModel = DataModel() var body: some Scene { WindowGroup { myDocumentView() .environment(dataModel) } } } I’ve been trying to make the app document based. Although I started using SwiftData, it has trouble with Codable (you need to explicitly code each eleme

I tried to use the .deny deleteRule but it seems to have no effect. The toolbar button adds an item with a relationship to a category to the context. Swiping on the category deletes the category even though an item is referencing the category. There is also no error thrown when saving the context. It is as if the deleteRule was not there. For other deleteRules like .cascade, the provided sample code works as expected. import SwiftUI import SwiftData @Model class Category { var name: String @Relationship(deleteRule: .deny) var items: [Item] = [] init(name: String) { self.name = name } } @Model class Item { var name: String var category: Category? init(name: String, category: Category) { self.name = name self.category = category } } struct DenyDeleteRule: View { @Environment(.modelContext) private var modelContext @Query private var categories: [Category] @Query private var items: [Item] var body: some View { List { Section(Items) { ForEach(items) { item in Text(item.name) } } Section

I have a SwiftUI document-based app that for the sake of this discussion stores accounting information: chart of accounts, transactions, etc. Each document is backed by a SwiftData DB. I'd like to incorporate search into the app so that users can find transactions matching certain criteria, so I went to Core Spotlight. Indexing & search within the app seem to work well. The issue is that Spotlight APIs appear to be App based & not Document based. I can't find a way to separate Spotlight data by document. I've tried having each document maintain a UUID as a document-specific identifier and include the identifier in every CSSearchableItem. When performing a query I filter the results with CSUserQueryContext.filterQueries that filter by the document identifier. That works to limit results to the specific file for search operations. Index updates via CSSearchableIndexDelegate.reindex* methods seem to be App-centric. A user may have file #1 open, but the delegate is being asked to update CSSearcha

PLATFORM AND VERSION Development environment: Xcode 16.4 (16F6), macOS 15.5 (24F74) Run-time configuration: iOS 18.3.1 DESCRIPTION OF PROBLEM I cannot build my app due to a module not found error when I'm importing Sample-Swift.h header to an ObjectiveC file. I need to use Swift code to ObjectiveC file with Swift code using an external XCFramework. It seems to be related to a mix with ObjectiveC and Swift code when Swift code uses class inheritance from FZWorkoutKit class. With a full Swift project, no issue. STEPS TO REPRODUCE Project https://fizzup.s3.amazonaws.com/files/public/Sample-WK.zip Open the provided project and try to build it. The issue occurs. In MyObject.m file, if you comment the first import (Sample-Swift.h), no issue occurs but I cannot use my Swift code (MyFile class). Uncomment the line commented in step 1. Go to MyFile.swift and change class inheritance from GoModeController (from FZWorkoutKit framework) to UIView (from UIKit). No issue occurs.

I'm building a SwiftUI app using SwiftData. In my app I have a Customer model with an optional codable structure Contact. Below is a simplified version of my model: @Model class Customer { var name: String = var contact: Contact? init(name: String, contact: Contact? = nil) { self.name = name self.contact = contact } struct Contact: Codable, Equatable { var phone: String var email: String var allowSMS: Bool } } I'm trying to query all the Customers that have a contact with @Query. For example: @Query(filter: #Predicate { customer in customer.contact != nil }) var customers: [Customer] However no matter how I set the predicate I always get an error: BugDemo crashed due to an uncaught exception NSInvalidArgumentException. Reason: keypath contact not found in entity Customer. How can I fix this so that I'm able to filter by contact not nil in my Model?
