无法使用NSCompoundPredicateType.OrPredicateType

Question

我正在尝试通过使用OrPredicateType分配其谓词来创建CKSubscription。虽然可以使用AndPredicateType保存CKSubscriptions，但我无法使用＆＃39; OR＆＃39;来保存订阅。谓语。有没有人遇到过类似的问题？ 这是我的代码：

        let aName = "John"
        let anotherName = "Jane"
        let aNamePredicate = NSPredicate(format: "name = %@", aName)
        let anotherNamePredicate = NSPredicate(format: "name = %@", anotherName)
        let namePredicates = NSCompoundPredicate(orPredicateWithSubpredicates: [aNamePredicate, anotherNamePredicate])
        let aSubscription = CKSubscription(recordType: "Employee", predicate: namePredicates, subscriptionID: "nameSubscription", options: [.FiresOnRecordCreation, .FiresOnRecordUpdate, .FiresOnRecordDeletion])

我收到此错误：
