I'm trying to subscribe to push notifications using CloudKit. I'm getting this error:

```
<CKError 0x170c5b1e0: "Unknown Item" (11/2003); server message = "could not find required field fieldID="25""

```

from this code:

```
let subscription = CKSubscription(recordType: "PlayerData", predicate: NSPredicate(format: "TRUEPREDICATE"), options: CKSubscriptionOptions.FiresOnRecordCreation)
let notificationInfo = CKNotificationInfo()
notificationInfo.shouldBadge = false
subscription.notificationInfo = notificationInfo
PublicDb.saveSubscription(subscription, completionHandler: { (returnedSubscription: CKSubscription!, error: NSError!) in
     println("\(error)")
})

```

But I don't have a field called "fieldID" nor I have any kind of reference to it in my entire project. I don't know where the 25 comes from either. It still happens if I change my record type and/or NSPredicate.

I also tried setting this but nothing

```
notificationInfo.shouldSendContentAvailable = true

```

This used to work for me, but now I cannot make it work anymore. Seems like my database got corrupted somewhere. I tried deleting the record type and recreating but no luck.
