PFQuery issue with NSpredicate

[topslave]

Hi,
I am building a chat application using Livequery, the chat works well with

      let predicate = NSPredicate(format:"itemID = '\(itemId1)' OR itemID = '\(itemId2)'")
        query = Message.query(with: predicate)?.order(byAscending: "createdAt")
       let query = PFQuery(className: MY_CLASS_NAME, predicate: predicate)

this works well if I don't use live queries and pull with time interval.
Livequery also works if I don't add predicate.
Below is the error I get
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid type in JSON write (PFQuery)'

any ideas ?
Thanks

Closing at the same issue is tracked there: parse-community/ParseLiveQuery-iOS-OSX#156

Feel free to open a PR.

As a work around, instead of making an $or query you can use the containedIn:

Message.query()?.whereKey("itemId", containedIn: [itemId1, itemId2])

This is more efficient also server side as it will be resolved in a single query.
