18. RealmSwift (Soon!)
19. RealmSwift let realm = RLMRealm.defaultRealm() realm.beginWriteTransaction() realm.addObject(mydog) realm.commitWriteTransaction() let allDogs = Dog.allObjects() for dog in allDogs { let dog = dog as! Dog let ownerNames = dog.owners.map { $0.name } println("\(dog.name)") }
20. RealmSwift let realm = Realm() realm.write { realm.create(Person.self, value: ["John", [["Fido", 1]]]) realm.create(Person.self, value: ["Mary", [["Rex", 2]]]) } // Log all dogs and their owners using the "owners" inverse relationship let allDogs = realm.objects(Dog) for dog in allDogs { let ownerNames = dog.owners.map { $0.name } println("\(dog.name)") }
