13. WWDC 2016 kk@realm.io
14. What’s new in Core Data kk@realm.io
15. What’s new in Core Data • Simple Core Data Stack • NSPersistentStoreDescription (Like RealmConfiguratin?) • Type safety • Subclass generation • Version Pinning jp@realm.io kk@realm.io
16. Simpler Core Data Stack kk@realm.io lazy var managedObjectModel: NSManagedObjectModel = { let modelURL = NSBundle.mainBundle().URLForResource("Example", withExtension: "momd")! return NSManagedObjectModel(contentsOfURL: modelURL)! }() lazy var persistentStoreCoordinator: NSPersistentStoreCoordinator? = { var coordinator: NSPersistentStoreCoordinator? = NSPersistentStoreCoordinator(managedObjectModel: self.managedObjectModel) let url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("Example.sqlite") var error: NSError? = nil var failureReason = "There was an error creating or loading the application's saved data." if coordinator!.addPersistentStoreWithType(NSSQLiteStoreType, configuration: nil, URL: url, options: nil, error: &error) == nil { coordinator = nil NSLog("Unresolved error \(error), \(error!.userInfo)") abort() } return coordinator }() lazy var managedObjectContext: NSManagedObjectContext? = { let coordinator = self.persistentStoreCoordinator if coordinator == nil { return nil } var managedObjectContext = NSManagedObjectContext() managedObjectContext.persistentStoreCoordinator = coordinator return managedObjectContext }()
17. Simpler Core Data Stack kk@realm.io lazy var persistentContainer: NSPersistentContainer = { let container = NSPersistentContainer(name: "Example") container .loadPersistentStores(completionHandler: { (storeDescription, error) in if let error = error { fatalError("Unresolved error \(error), \(error.userInfo)") } }) return container }()
18. Typed fetch request kk@realm.io let request: NSFetchRequest<Dog> = Dog.fetchRequest() request.predicate = Predicate(format: "...") request.fetchBatchSize = 20 let dogs = try! persistentContainer.viewContext.fetch(request) print(dogs)
19. Typed fetch request kk@realm.io let request: NSFetchRequest<Dog> = Dog.fetchRequest() request.predicate = Predicate(format: "...") request.fetchBatchSize = 20 let dogs = try! persistentContainer.viewContext.fetch(request) print(dogs)
20. Insert kk@realm.io let dog = Dog(context: persistentContainer.viewContext) ... try! persistentContainer.viewContext.save()
21. Backgroud task kk@realm.io let context = persistentContainer.newBackgroundContext() ...
22. Backgroud task kk@realm.io persistentContainer.performBackgroundTask { (context) in ... }
23. Auto generation subclasses kk@realm.io import Foundation import CoreData class Dog: NSManagedObject { } extension Dog { @nonobjc class func fetchRequest() -> NSFetchRequest<Dog> { return NSFetchRequest<Dog>(entityName: "Dog"); } @NSManaged var age: Int64 @NSManaged var name: String? }
