Make sure that either in your code you implemented dataSource and linked it to your UICollectionView or you can do that using the Storyboard.

The crash was solved by reseting the UICollectionview datasource to nil in deinit This post helped understand what's going on https://github.com/ReactiveX/RxSwift/issues/1154
