@Dong1108 did you ever figure this out? I am having what looks to be a similar issue:

I want to say, that this may be caused by trying to reloadData() on an optional collectionView in my layout and the collectionView was deallocated before it could do so... but I am not sure

This library swizzles a couple of methods, namely -reloadData. The crash you're seeing is likely nothing with the library, but the swizzled method hiding the true cause of the crash. If you set the tableView's emptyDataSource and emptyDelegate both to nil to disable using this library you should see what the true cause of the crash is.

@colinhumber I just removed DZNEmptyDataSet from project and used an alternative project

@mmdock Fair enough! At any rate, if you run into this again, typically the swizzled method is fine but can hide the true crash location.
