CollectionView in TableView

There's nothing in particular stopping you from putting any kind of content inside a table view cell, so, yes, you can put a collection view there. Whether it turns out to be a good user experience is another question.

Note that you'll actually need a scroll view with a collection view inside it, if you want it to scroll horizontally, but that's what you get if you drag a collection from IB's object library onto your canvas. If you're doing this programmatically, you'll have to create the scroll view yourself.

But actually when i try to connect my ViewCollection with my ViewController, i recieve Error "Outlets cannot be connected to repeating content". When i try to create it manualy, inside my function tableView(), the column which contains the ViewCollection isn't recognise.
