CKSubscription型CKSubscriptionOptionsFiresOnRecordUpdate不起作用

Question

我設置一個CKSubscription用下面的代碼：

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"TRUEPREDICATE"]; 
CKSubscription *subscription = [[CKSubscription alloc] initWithRecordType:@"RecordTypeName" 
                   predicate:predicate 
                  subscriptionID:@"Subscription1" 
                    options:CKSubscriptionOptionsFiresOnRecordCreation | CKSubscriptionOptionsFiresOnRecordUpdate]; 

CKDatabase *privateDatabase = [[CKContainer defaultContainer] privateCloudDatabase]; 
[privateDatabase saveSubscription:subscription completionHandler:^(CKSubscription * _Nullable subscription, NSError * _Nullable error) { 
    if (error) { 
     NSLog(@"Failed to subscribe."); 
    } 
}]; 

在application:didReceiveRemoteNotification:當添加一個新的記錄我得到通知，但在現有的記錄被更新，我從來沒有得到通知。

我試過從CloudKit儀表板和從另一臺設備登錄到同一個帳戶更新記錄。

我測試在iOS 9測試版5.

它是一個已知的bug是更新通知不工作。
