持久存储迁移期间发生错误（无法就地迁移存储）Core Data

问题描述 投票：0回答：0

我添加了新的模型版本并像默认一样选择它。然后我在新模型版本中向现有实体添加了新属性。为了测试迁移，我安装了以前版本的应用程序并添加了应用程序中的所有数据。然后我安装新的更改并在模拟器上运行。如果我将该构建移动到 TestFlight 并通过真实设备进行测试，则会收到此错误：

Fatal error: ###persistentContainer: Failed to load persistent stores:Error Domain=NSCocoaErrorDomain Code=134110 "An error occurred during persistent store migration." UserInfo={sourceURL=file:///private/var/mobile/Containers/Shared/AppGroup/DBB80C75-1B07-4318-8BA3-3F4FFC14FBD7/AppName.sqlite, reason=Cannot migrate store in-place: near "null": syntax error, destinationURL=file:///private/var/mobile/Containers/Shared/AppGroup/DBB80C75-1B07-4318-8BA3-3F4FFC14FBD7/AppName.sqlite, NSUnderlyingError=0x281958180 {Error Domain=NSCocoaErrorDomain Code=134110 "An error occurred during persistent store migration." UserInfo={reason=near "null": syntax error, NSSQLiteErrorDomain=1, NSUnderlyingException=near "null": syntax error}}}

我也需要为 Widget 的目标使用 CoreData。代码在这里：

final class CoreDataStack {
    static let shared = CoreDataStack()
    var context: NSManagedObjectContext { persistentContainer.viewContext }
    var container: NSPersistentContainer { persistentContainer }
    private let containerName = "AppName"
    private var persistentContainer: NSPersistentContainer!

    // MARK: - Setup

    func setup() {
        guard let storeURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "app_group")?.appendingPathComponent(containerName + ".sqlite") else {
            fatalError("Error finding Model from File Manager")
        }
        let container = NSPersistentContainer(name: containerName)
        let description = NSPersistentStoreDescription(url: storeURL)
        description.type = NSSQLiteStoreType
        description.shouldMigrateStoreAutomatically = true
        description.shouldInferMappingModelAutomatically = true
        container.persistentStoreDescriptions = [description]
        container.viewContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy
        container.viewContext.transactionAuthor = appTransactionAuthorName
        container.viewContext.automaticallyMergesChangesFromParent = true
        container.loadPersistentStores(completionHandler: { (_, error) in
            if let error = error as NSError? {
                let crashlitycService: CrashlitycUseCase = CrashlitycService()
                crashlitycService.record(error: .errorForAnalytic(error), file: #file, function: #function, line: #line)
                fatalError("###\(#function): Failed to load persistent stores:\(error)")
            }
        })
        self.persistentContainer = container
    }
}

iOS 16.2 Xcode 14.1

我在这里发现的类似问题，但没有成功：

  1. 在 iOS 13 中迁移 Core Data 持久存储期间发生的错误
  2. iOS 应用程序由于核心数据迁移而在启动屏幕上崩溃

我通过添加 2 个属性更新了 

RepeatedDateCD
：
itemState
，
notificationSource
。都是
Int16
，不可选。 这是迁移日志：

请帮我弄清楚如何进行此迁移？
