Running the demo thats provided, I am getting a 'Can only add notification blocks from within runloops.' RLMException. This is happening on Realm 0.97.0, everything appears to be working fine on versions < 0.97.0.

Great if you could implement compatibility for Carthage

Define the fetchedResultsController variable with public access (read-only). Probability for access count of resuts.

I have crash

How to reproduce:
I setup to sectionNameKeyPath of MainGridController vc value "kicker"

RBQFetchedResultsController just got updated, and the fixed a typo.

So, the private routine updateFetchedResultsController(), no longer compiles.

The last argument label in self.fetchedResultsController.updateFetchRequest was "andPeformFetch". It is now changed to "andPerformFetch" in 4.0 of RBQ, spelling "perform" correctly.

Use realm's notifications directly.

I refactored my app to use RealmGridController because I was running into a random crash. It all appeared to be working well, except today I started seeing the very same crash:

Fatal Exception: NSInternalInconsistencyException
Invalid update: invalid number of items in section 0. The number of items contained in an existing section after the update (14) must be equal to the number of items contained in that section before the update (14), plus or minus the number of items inserted or deleted from that section (1 inserted, 0 deleted) and plus or minus the number of items moved into or out of that section (0 moved in, 0 moved out).

RealmGridController.swift line 316 specialized

This sounds like a race condition? Am I understanding correctly that the count remains the same even though a new item is being added? So the count is being taken before the item actually makes it to the count() method? or?

Any suggestions on how to get to the bottom of this?
