Answer 1

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

Answer 2

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
