Make sure you don't try to instantiate instance of Realm() before migration config is set in application(application:didFinishLaunchingWithOptions:). When it crashes check execution stack to find which instance raised exception. I had the same error, in my case Realm instance in one of my view controllers were instantiated before migration block was set.
