I added new model version and select it like default one. Then I added new attribute to existing entity in new model version.
To test migration I installed previous version of app and add filled with all data in app. Then I install new changes and it work on simulator. If I move that build to TestFlight and test via real device then I get this error:
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."

I need to use CoreData for Widget's target as well. Code is here :
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
}
}
