@Claude31 I have found the problem. I have 2 more CollectionViews in GenericHomeCollectionViewCell; one for numbers under the news and another one for the right menu. When I disable those 2 collection views, the application launched without any problems, and my newsCollectionView populated with the data. I guess the cells were trying to dequeue for those collectionViews, not my newsCollectionView. Any idea how can I work around this?

Thank you for the answer. I have seen this method while searching for how to pause the stream. I couldn't even try it because the problem is, I can't reach the web view from the view controller. I can pass this to nib but when I try to do this, I get webView = nil. It is like the web view gets destroyed after initialize.
