“SwiftData inheritance relationship”

问题描述: 环境: Xcode 版本: 16.3 *macOS 版本: 15.4 项目类型: SwiftUI App with SwiftData 问题摘要: 当在 Xcode 项目的 Signing & Capabilities 中为启用了 iCloud 能力的应用关联一个具体的 iCloud Container 时，即使代码中并未显式启用 CloudKit 同步（例如，未在 ModelConfiguration 中设置 cloudKitDatabase），SwiftData 的 ModelContainer 在应用启动初始化时也会立即失败并导致崩溃。如果仅启用 iCloud 能力但不选择任何 Container，应用可以正常启动。此问题在使用空的 Schema([]) 进行测试时依然稳定复现。 复现步骤 (使用最小复现项目 - MRE): 使用 Xcode 16.3 创建一个新的 SwiftUI App 项目 (例如，命名为 CloudKitCrashTest)。 在创建时不要勾选 Host in CloudKit，或者，如果勾选了，先确保后续步骤覆盖相关设置。Storage 选择 None 或 SwiftData 均可复现。 修改 CloudKitCrashTestApp.swift 文件，添加 SwiftData 导入和基本的 ModelContainer 初始化逻辑。关键代码如下： import SwiftUI import SwiftData @main struct CloudKitCrashTestApp: App { let sharedModelContainer: ModelContainer init() { // 使用空 Schema 进行诊断 let schema = Schema([]) // *不* 指定 cloudKitDatabase let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) do { sharedModelContainer = try ModelContainer(for: schema, configurations: [modelConfi

I'm following the flow to get my reports data: get the requests (ONGOING or ONE_TIME_SNAPSHOT) for my app (https://api.appstoreconnect.apple.com/v1/apps/{{appID}}/analyticsReportRequests?filter%5BaccessType%5D=ONGOING) get the report (App Sessions Standard, for example) (https://api.appstoreconnect.apple.com/v1/analyticsReportRequests/{{requestID}}/reports?filter%5Bname%5D={{report}}) get the daily instances of the ONGOING request (https://api.appstoreconnect.apple.com/v1/analyticsReports/{{reportID}}/instances?filter%5Bgranularity%5D=DAILY) get the segments for the selected instance (https://api.appstoreconnect.apple.com/v1/analyticsReportInstances/{{instanceID}}/segments) This flow used to work fine, but recently I noticed that the earliest instances (mostly of processing date 2025-02-24 until 2025-02-27 return an error when I'm trying to get the instance segments usint the URL https://api.appstoreconnect.apple.com/v1/analyticsReportInstances/{{instanceID}}/segments. The error is the following: title: The s

Is there a way to prevent or handle our application's crash if a third-party library makes a bad memory access? Basically, I want to know if using a buggy library (that causes bad memory access) will automatically make our application inherit those crashes, leading to our app crashing as well. If there is a way to prevent the crash, what methods can be used to do so? Thread 13: EXC_BAD_ACCESS (code=1, address=0x3a7d300)

If use a SortDescriptor for a model and sort by some attribute from a relationship, in DEBUG mode it all works fine and sorts. However, in release mode, it is an instant crash. SortDescriptor(.name, order: .reverse) ---- works SortDescriptor(.assignedUser?.name, order: .reverse) ---- works in debug but crash in release. What is the issue here, is it that SwiftData just incompetent to do this?

Setup I am running a versionedSchema for my SwiftData model and attempting a migration. The new version contains a new attribute, with a type of a new custom enum defined in the @Model class, a default value, and a private(set). Migration was completed with a migrationPlan with nil values for willMigrate and didMigrate. Example - Previous Version @Model class MyNumber { var num: Int init() { // Init Code } } Example - Newest Version @Model class MyNumber { var num: Int private(set) var rounding: RoundAmount = MyNumber.RoundAmount.thirtyMinute init() { // Init Code } enum RoundAmount { case fiveMinute, tenMinute, thirtyMinute } } Issue Running this code, I get a swiftData error for “SwiftData/ModelCoders.swift:1585: nil value passed for a non-optional keyPath, /MyNumber.rounding” I assume this means a failure of the swiftData lightweight migration? I have reverted the version, removed private(set) and re-tried the migration with no success. Using the versionedSchema with mig

Hi there, I got two models here: Two Models, with Many-To-Many Relationship @Model final class PresetParams: Identifiable { @Attribute(.unique) var id: UUID = UUID() var positionX: Float = 0.0 var positionY: Float = 0.0 var positionZ: Float = 0.0 var volume: Float = 1.0 @Relationship(deleteRule: .nullify, inverse: Preset.presetAudioParams) var preset = [Preset]() init(position: SIMD3, volume: Float) { self.positionX = position.x self.positionY = position.y self.positionZ = position.z self.volume = volume self.preset = [] } var position: SIMD3 { get { return SIMD3(x: positionX, y: positionY, z: positionZ) } set { positionX = newValue.x positionY = newValue.y positionZ = newValue.z } } } @Model final class Preset: Identifiable { @Attribute(.unique) var id: UUID = UUID() var presetName: String var presetDesc: String? var presetAudioParams = [PresetParams]() // Many-To-Many Relationship. init(presetName: String, presetDesc: String? = nil) { self.presetName = presetName self.presetDesc =
