Based on filter results, I need to change the flow layout of a collection view and reload the data using a different kind of cell. However you can't just do this:

myCollectionView.flowLayout = ...

So how is it possible to change the flow layout of a collection view?

LONG ANSWER

You said:

However you can't just do this:

 myCollectionView.flowLayout = ...

But in fact you can set the collection view's collectionViewLayout , and it does just what you want:

Assigning a new layout object to this property causes the new layout to be applied ... to the collection view's items.
